Yes, he might be able to do so - but it's also possible that the provider has disabled parsing of the .htacess file.

attached mail follows:
Some versions of IE will "sniff" the file to determine what type it is rather than taking your word for it that you REALLY want to download the file. From my memory this is IE 4, and IE 5.5 where this is a problem. The way I dealt with this is to totally make up an application type that IE will not have a helper app for... such as "new/type" or whatever you want. This should then trick IE into forcing a download. The other trick I noted was that IE 5.5 doesn't like the "attachement" keyword in the Content-Disposition header. Don't ask me why, all I know is that it won't pick up the supplied filename if you include it. That is from my experiences in forcing download files and it seems to work out once you figure out every combination of what does/doesn't work for the various versions of IE. Netscape is always fine, and I haven't tried any others extensively.
Fiddle with the various headers for the different IE browsers and you will get it to work.

Probably not.
You'll have to suck the GIF down into a local file, and then use CreateImageFromGIF, I think.

Goody - a recursive routine. I have just the thing-
// Dirs you don't want listed $badlist = "secret phpMyAdmin stats test tools"; $bad_dirs = explode(" ", $badlist); $docroot = "/usr/local/apache/htdocs/"; $basedir = $docroot;
function read_files($dirname) { global $filelist; $dirid = opendir($dirname); while($entry = readdir($dirid)): $this = $dirname . '/' . $entry; if ( (is_file($this)) && ($entry != ".") && ($entry != "..") && (!eregi("old$",$entry)) && (!eregi("bck$",$entry)) && (strstr($this, ".htm") || strstr($this, ".html") || strstr($this, ".php"))): $filelist[] = $entry; endif; endwhile; }
function exclude_dir($dirname) { global $bad_dirs; $outcome = false; while(list($key, $value) = each($bad_dirs)): if (strstr("$dirname", "$value")): $outcome = true; endif; endwhile; reset($bad_dirs); return $outcome; }
function recurse_dir($basedir) { global $dirlist; $dirid = opendir("$basedir"); while ($entry = readdir($dirid) ) { $this = $basedir . $entry; if ( (is_dir($this)) && ($entry != ".") && ($entry != "..") && (!exclude_dir("$this/"))) { $dirlist[] = $this; recurse_dir("$this/"); }; }; }; ?>
Call it with recurse_dir(dir-to_start) and get the results in $dirlist[] Have fun. And yes, there's room for improvement, having looked at it for the first time in a year or so :-) The first obvious would be to return $dirlist....

A lock is just a degenerate case. A slightly less degenerate case (that can't be implemented with flock) is when you want to allow N users of the resource instead of just one.

I admit I haven't looked at this hard enough to understand all the details, but could message queues help you out here? You could get higher throughput since the server fills the buffer and calls msgsnd() beforehand, whereas in your signalling implementation clients will stall between the time they signal the server and the time the server has filled a buffer for them. Also, you need some additional overhead to manage the buffer handoff from client to server. And doing things in signal handlers can get dicey.
If a message queue isn't big enough for you, you can pass references to shared memory in your messages.

I don't remember why either. I did that code somewhere around the end of 1998 . . .

I no longer use php or maintain any of the stuff I helped with (aside from answering the occaisional question, like this one.

Me either.
Tom.
attached mail follows:
There probably should be a full implementation of semaphores in php. If you have a need for this, we should discuss exactly how it should be implemented. I will have some free time available soon, so I can start working on this. Though I have a couple other projects as well. If you would be interested in contributing a CVS account can be arranged. This should probably start as a separate module, and then eventually replace the sysvsem extension as it is no long being actively maintained.
I have a great desire for php to function well as a standalone scripting language as well as web, so I am always interested as projects like this.
Is there anyone else who would find this useful?

As far as creating the new module goes, it shouldn't be 'to much effort'. The basic implimentation of system v semaphores is actualy quite simple, its the usage of sempahores that can be very confusing :-) sysv sem's are often refered to as the most difficult to comprehend of the sysv standards.
I would be more then willing to donate my time and efforts to that project, and i do have some knowledge of how semaphores can be used (reader-writer, resource count and lock implimentations). However as i mentioned before, my last C project is some years ago, also my knowledge of Zend internals is limited to the php-usage scope
do note a locked semaphore == 0, any value above 0 allows for a 'lock', this is done to allow multiple client-locks clasical example is : if the printer manager daemon has 5 printers, it creates a semaphore with a max_acquire of 5. (so acquire count == 5). Every client connecting, lowers that count... untill its zero. Then the client blocks 'till the value is positive again.
Proposed API of the sysvsem -----------------------------------
* $sem = sem_get($key,$max_acquire,$perms) Gets or creates a semaphore id, id is returned in $sem * $ret = sem_acquire($sem) Tries to lowerer the acquire count of the semaphore. If count is already 0, wait till it is raised (by sem_release) or returns an error (sem_remove was called or invalid permission to get semaphore). note: when the client blocks 'semzcnt' is increased (semzcnt = # of processes waiting for lock) * $ret = sem_release($sem) Increases the acquire count
[proposed new function] * $count = sem_get_waiting($sem) Returns the amount of processes blocking on a semaphore acquire call. I propose -1 = error, 0 > incicates # of waiting processes.
Man Pages ------------- man pages in linux are avail for: * semget * semop * semctl
more info can be found on the url i posted in orig email, it explains the sem api decently.
Documentation ------------------ I'd be happy to help write up some documentation, general how-to-use semaphores for usage in php docs, plus some example implimentations..
I will see how far i can get using the existing implimentation as a template for implimenting a php module.. however be sure i'll come knocking for help fairly soon :-)

I'm starting to do it the right way (tm). That is, I start to not do it like you do anymore, but instead try to use templates as much as possible. This doesn't clutter up your PHP code with HTML and thus makes it easier to read.
I use Smarty (www.phpinsider.com). I haven't tested anything else and find it quite easy to use.

Jump out for anything more than three lines of pure HTML.
Your HTML will be much easier to read.
Speed-wise, it just doesn't matter, unless you intentionally alternate back-and-forth every other line... Even then, the difference is negligible.

If you call the function Header, like: Header($name.".php");
Then there's an possibility that $name (your variable name) isn't set. Could you supply the part of your code where you call Header? That should make the problem better traceable.

it's the text that header() is printing that's causing problems.

There's my code below:
header("Location:loggedon.php?SID=$SID"); exit;
I know the file is there cause I look right at it when I do an ls command. I also know that the $SID variable is set cause I've echoed that out before the header(). The header() seems not to work on files that are in the same directory that the header() calls. However, when I put say yahoo.com in the header() it works fine, it just doesn't seem to work when I call local files.

The first thing is that 2-dimensional arrays don't really exist in php. Any
element of any array can be another array. The second important point is
that all php arrays are associative. If you don't declare the key of an
element (e.g. $out[] = "fred") when creating it you get the next integer
available as the key. Your initial declaration creates ...
$out[0] = $name; $out[1] = $srch; $out[2] = $sel; $out[3] = $case; $out[$qvalues][0] = $vals; $out[$qvalues][1] = $valtypes;
with $name, etc. being whatever the variables are at the time the array is initialised.
What I think you wanted (I'm not entirely sure) is more along the lines of .. for ($i=0; $I < $num_out; $I++) $out[] = array("name"=>$name, "srch"=>$srch, "sel"=>$sel, "case"=>$case, $qvalues => array($vals, $valtypes));
I'm not entirely sure what you're trying to do but I hope this points you in the right direction.

Subject: Multi-dimensional array issue
Hi from a recent PHP convert,
Having a heck of a time declaring and accessing 2 dimensional info in an array. any input on where to start looking for the answer would be greatly appreciated.
I want to have a base array of 5 elements. The first 4 elements are variables, and the fifth is an array of 2 elements. seemed harmless enough at the time;)
Coding conventions suggest access to the first level of elements is: $basearray[base_numerical_offset][$basearray_variable] and this works great for accessing the first 4 elements of the base array.
Accessing the fifth elements' variables in the next dimension is where it fails for me:
$basearray[base_numerical_offset][$subarray][sub_numerical_offset][$subarray _variable]
The documentation/snippets/samples, etc. have been to no avail; still can't get to elements in the second dimension properly. Attempts to populate the second level array trahses the entire structure.
I have the following declaration: $out => array($name, $srch, $sel, $case, $qvalues => array($vals, $valtypes); $out is the name of the base array $qvalues is the name of the sub-array under the base array "$out" I need for each $out array to consist of a name, srch, sel, case and then a variable number of qvalues array elements that each have single vals and valtypes elements.
Use the following snippet to see what happens; it's not what I had hoped to see. I hope I'm just doing something wrong..
Thanks, Ken.

Hi ,
I'm having problems with my session_unregister(). Maybe what i'm trying to do can't be done but I would like someones opinion. This is what I am doing and why i'm doing it.
session_start(); session_unregister(val_1); session_register(val_1);
I am doing this to clear the contents of val_1 before I use it again. Needless to say its not working. val_1 always contains the same value until I close the browser. How should I go about it?
P.S. Sorry if you've seen a similar post yesterday, I just never got a reply.

session_registering()'ing a variable just puts it in a list of names of the session variables. session_unregister() just removes the name from the list. Neither function affects the variable's value.
To clear the variable's value, just assign it to blank, or call unset() on it, e.g.,
$val_1 = ""; unset($val_1);
There is no need, or use, in unregistering it, then registering it again.

Dear sir,
In order to transfer out (USD 126 M) One hundred and twenty six million United States Dollars) from African Development Bank. I have the courage to ask you to look for a reliable and honest person who will be capable for this important business believing that you will never let me down either now or in future.
I am mr CEASER BENENE. the Chief auditor of African Development Bank (ADB). There is an account opened in this bank in 1980 and since 1990 nobody has operated on this account again. after going through some old files in the records I discovered that if I do not remit this money out urgently it will be forfeited for nothing. the owner of this account is Mr. Smith B. Andreas, a foreigner, and a miner at kruger gold co., a geologist by profession and he died since 1990. no other person knows about this account or any thing concerning it, the account has no other beneficiary and my investigation proved to me as well that this company does not know anything about this account and the amount involved is (USD 126M) One hundred and twenty six million United States Dollars million dollars. I want to first transfer USDM twenty six million United States Dollars from this money into a safe foreigners account abroad before the rest, but I don't know any foreigner, I am only contacting you as a foreigner because this money can not be approved to a local bank here, but can only be approved to any foreign account because the money is in us dollars and the former owner of the account is Mr. Smith B. Andreas is a foreigner too. I know that this message will come to you as a surprise as we don't know our selves before, we will sign agreement, but be sure that it is real and a genuine business. I only got your contact address my from my secretary who operates computer, with believe in god that you will never let me down in this business you are the only person that I have contacted in this business, so please reply urgently so that I will inform you the next step to take urgently. Send also your private telephone and fax number including the full details of the account to be used for the deposit.
I want us to meet face to face or sign a binding agreement to bind us together so that you can receive this money into a foreign account or any account of your choice where the fund will be safe. and I will fly to your country for withdrawal and sharing and other investments.
I am contacting you because of the need to involve a foreigner with foreign account and foreign beneficiary. I need your full co-operation to make this work fine. because the management is ready to approve this payment to any foreigner who has correct information of this account, which Iwill give to you later immediately, if you are able and with capability to handle such amount in strict confidence and trust according to my instructions and advice for our mutual benefit because this opportunity will never come again in my life. I need truthful person in this business because I don't want to make mistake I need your strong assurance and trust.
With my position now in the office I can transfer this money to any foreigner's reliable account which you can provide with assurance that this money will be intact pending my physical arrival in your country for sharing. I will destroy all documents of transaction immediately we receive this money leaving no trace to any place. you can also come to discuss with me face to face after which I will make this remittance in your presence and two of us will fly to your country at least two days ahead of the money going into the account.
I will apply for annual leave to get visa immediately I hear from you that you are ready to act and receive this fund in your account. I will use my position and influence to effect legal approvals and onward transfer of this money to your account with appropriate clearance forms of the ministries and foreign exchange departments.
At the conclusion of this business, you will be given 35% of the total amount, 60% will be for me, while 5% will be for expenses both parties might have incurred during the process of transferring.
I look forward to your earliest reply through my email address or by my tel:874-762-72-7947,fax:874 762 727949.
yours truly
mr.CEASER.

Uncompressing should not take that much time. And you can speed it up by using the zlib functions instead of a exec (gunzip ...) http://php.net/gzopen
Also, if the file to be uncompressed is very large, you should cache the results (the generated plots).

Another part of this is an external program on the server that can't read from the gzipped file. The file has to be uncompressed, unfortunately. The resulting uncompressed file is recompressed through a cron job after 30 days if it hasn't been used for 30 days.
I came up with something that appears to work WRT the pop up dialog problem. In my main browser window, from Javascript, I pop up an alert telling the luser the unzip is beginning. Then in the gunzip code, in the <BODY>, I do this:
print("<BODY"); print(" onUnload=\"alert('Finished uncompressing $datafile... please " . "refresh main window.')\"\n");
And I use Javascript to close the window. Now I just need a way to automatically refresh the main browser window and I'm happy.
Thanks for the help!

This is the code in the first page that I visit.
<? session_start(); $check0 = session_is_registered("fb"); $check1 = session_register("fa"); $check2 = session_is_registered("fa"); $check3 = isset($HTTP_SESSION_VARS["fa"]); $HTTP_SESSION_VARS["fa"] = "avalue"; $check4 = isset($HTTP_SESSION_VARS["fa"]);
echo "check0=$check0<br>check1=$check1<br>check2=$check2<br>check3=$check3<br>che ck4=$check4"; ?>
This is the output i get.
check0= check1=1 check2=1 check3= check4=1
apparently, session_is_registered and isset return null if they evaluate to false. I was expecting boolean true and false return values, but no matter i can work with it this way, just wondering if this is by design.?

What you were expecting is correct, boolean true/false. However, it appears that PHP converts these values to strings during the echo. true converts to the string 1, while a false string is the empty (null) string.
<? $a = true; echo "a is $a <br>"; $a = false; echo "a is $a <br>"; ?>

There isn't such a thing as boolean true or false in PHP. In PHP, everything other than NULL, FALSE, 0 and "" (empty string) is considered to be TRUE if used in a boolean context.

This is definitely not the case. Two things to try:
1. In page2, put some logic around the "session_register("FailedLogins");", otherwise you re-register on every visit. I don't think this affects the variable's value, but it is definitely wasted cycles.
2. If register_globals is set to "on" in php.ini, and you are using a PHP version earlier than 4.0.6, then the code below probably won't work. If this is the case, just use the global variable, $FailedLogins, instead of $HTTP_SESSION_VARS["FailedLogins"] everywhere.

I hear ya.
After playing around with this, your approach works if register_globals is set to off (I did this with an .htaccess file). I'm surprised by this. It appears that the global version of a variable still overwrites the HTTP_SESSION_VARS version when the script ends and the data is stored to the session file, in spite of the change in this area in 4.0.6. This is not the behavior I expected with this bug fix, but it appears to be the case. Since your code never sets the global version of $FailedLogins, nothing gets stored in the session.
Unless I'm missing something, it looks like register_globals needs to be off to use session variables the way your code does. In case you haven't done this before, create .htaccess with this line:
php_flag register_globals off
All for me on this day. Good luck!

hi,
I'm using the form file object for uploading a file because php using ftp isn't supported on my provider but everthing ok so far.
Now the http user (lets say the user that php is running on) is owner of the file, I want to change this to the user I am (the ftp user) hosting is running linux and I'm a real user there.
is it possible to change user ?
kind regards Jeroen Olthof

You can try: http://php.net/chown http://php.net/chmod http://php.net/umask
and various other functions that accept a permissions argument (fopen?) and see if any of them will let you do this...
Probably not, since then *ANY* PHP-scripter on your server could hijack your account, and that would be bad, eh?
What your IPS *MIGHT* do is create a GROUP with you and nobody user in it, and you *MIGHT* be able to chgrp the file to that group, and you *might* be able to do what you need to do with that file then...

If you're talking about the PHP page itself, try $PHP_SELF. If you want to know what page sent the form data to the PHP page, try $HTTP_REFER. Be careful, though, as not every browser sends the referring page along with a request, leaving $HTTP_REFER empty.

One way around this is to make the first page just a dummy that starts a session then redirects to the real first page, with the session id passed on the redirect URL.

Why does it matter if they hit refresh and get a new session ID before you've collected any information about that ID?...
About all you *COULD* do is have a "fake" first page that does:
<?php $session_id = md5(rand()); header("Location: page2.php?session_id=$session_id"); ?>
They can now reload the "second" (first they'll see) page as much as they want.

Good user interface design can be difficult to achieve in a browser environment, and many of the browser form interfaces I have seen are poorly designed in terms of user experience.
I've created a multipart form without any "page expired" messages, no matter what the user does. It's pretty slick, as far as browser form interfaces go.
The user can use the browser back button, the browser forward button, the browser refresh button, or the form "next" button anywhere in the series of pages, all without disturbing any responses already entered.
Say they fill out 5 pages, then decide to go back and review the first page before completing page 6. In that case, I don't want to create a new session, and thereby discard all the responses already entered, in case they happen to hit refresh while on page 1.
Why? That's just good "user interface design 101."

Art Wells gave me an idea how to do it all on a single page, and here is what I worked out from his idea:
<? $PHP_SELF = $HTTP_SERVER_VARS['PHP_SELF']; session_start(); if (!session_is_registered('vsid')) { session_register('vsid'); $HTTP_SESSION_VARS['vsid'] = session_id(); $sidurl = "Location: $PHP_SELF" . '?' . SID; header("$sidurl"); exit(); } .... .... other code on first page .... ?>
Thanks to all for the ideas!

rather than try to create a regex, a few questions which may help peopl offer a better solution...
1) where are you getting the pages from... files? web sites? xml output? 2) do they appear as you posted in the web browser, or if you view source do they appear a little more organized (ie: the text is formatted, just not for HTML).
if all that you have to work with is a mix like you posted (no \n or \r\n in the blob at all) and if there is any wide variety in the descriptions or posts... you would have a difficult time creating a regex that would in one fell swoop correct all your problems.
if you have cr's and lf's in the file... we are in business.

Hi. I just joined the list and, of course, I have a question. I've searched for quite a bit of time now, but to no avail.. mostly, I suspect, because all the relevant search terms are to broad. But heres my problem:
I have a journal I whipped up and tweak often that uses PHP and MySQL (no small club there. :p ). The functionality I'm trying to add right now is to be able to enclose text in a <hide> tag (what? you didnt see that "hide"? html and email just don't mix) and it will not be displayed in the browser. example:
I had a good day today. <hide>I shot the milkman. </hide>Tho nothign much happened.
then i use: $entry_hidden = eregi_replace("<hide>.+</hide>","<hidden>",$entry);
and this works just fine, replacing the "secret" text with a non-displayed <hidden> tag. The problem arises when I use the tag 2 or more times:
Hey <hide>losers!</hide> I think that I <hide> do not</hide> like corn.
in this case, the above blurb gets outputted as: hey <hidden> like corn.
So how do I make it stop pattern-matching when it reaches the first instance of </hide>, and make it work properly for each subsequent set of the tag?
This is prolly something pretty basic in regular expressions, but in my limited working knowledge (and the 3 tutorials I've tried), it's not addressed. searches in the archive, the php manual, and google have also failed me. worthy list?
I thank you in advance and hope I can tolerate the mail volume long enough to return the favor.

".+" is 'greedy', meaning it consumes as much as text as it can. with perl-like regular expressions, you can add a trailing "?" which makes the + and * operators non-greedy.

Hi,
I'm working on a download script
header("Content-Type: application/octet-stream\n"); header("Content-Length: $size\n"); header("Content-Disposition: attachment; filename=\"$file\"\n"); header("Content-Description: Download\n"); readfile($path.$file);
This works, but when the initial file download box pops up it says downloading file download.php (the name of the script), instead of the filename. The correct filename does appear in the next save as box. Does anyone know how to get the filename to show up in the initial file download box? Or, alternatively, how to bypass the first box alltogether (like it is done at downloads.com, for example)?
Thanks,

header( "Content-Type: application/download" ); if (strstr(getenv('HTTP_USER_AGENT'), 'Netscape6' )) header( "Content-Disposition: attachment; filename=chopper.exe" ); else header( "Content-Disposition: filename=chopper.exe" ); $fn=fopen( "chopper.exe" , "r" ); fpassthru( $fn );
This was as close as I ever got. Still doesn't work in Konqueror but is an acknowledged bug.

Hi Folks!
I am working on a project where I need to encrypt some data that will be decrypted later by a visual basic application and also receive encrypted data from that application and decrypt it on the webserver. To exchange the data, I did some xml and everything went fine, but I can't tell you the same about the encryption.
We chose to use BLOWFISH cbc to encrypt the data on both ways (php and vb). On php I am using the mcrypt module and at the vb side, the guys are using a dll version of the Blowfish algoritm.
Well, we are starting to fight each other, me and the vb guys, because we can encrypt and decrypt data on our own applications, but the encrypted data from php cannot be decrypted by visual basic, and vice-versa.
Of course the key and the iv are the same on both sides and the data is converted to hexa before the encrypt process. I did a lot of tests according the manual and some other sources, and everything seems to be ok. The vb guys are telling me the same and we are all on a dilema now, and the time is becoming short....
If anybody knows something about it please let me know. Another point of views on doing this are welcome too.
Sorry for any language mistakes I did.
Regards
Alex

Don't do that either. All in one script.

You would have to use "cURL" to get those.
HTTPS pages require that the client (in this case PHP) negotiate a secure connection using SSL and thus sending back and forth some headers of public/private key-pairs.
cURL does this.
PHP's include() doesn't.

Just a quick addition... when a PHP script is run as a shell script from a Perl script (that make sense?) it cannot pass back exit variables to the Perl script...
Would love to be proven wrong on this as I had to dust off Perl programming for a RADIUS interface some time ago.

A FORM submission is supposed to return an HTML document, not a JPEG.
Have your return document look more like this:
echo "<IMG SRC=display.php?pathname=$form_data_name>";
Then, move your header() and fread into the display.php file.
The catch is the file is DELETED after the upload script finishes.
So what you *REALLY* need to do is use http://php.net/copy_uploaded_file first and pass the new home of that file into your display script.
If that infobar is being spewed out before your headers, though, you'll have to dink around some more, and *MAYBE* even go so far as to name your display.php script /screwy/display.jpeg, and have an .htaccess file in /screwy that makes JPEG get parsed by PHP. Your actual JPEGs then, should *NOT* go in /screwy/ but some place where they are just regular old jpeg files...
You may be able to avoid that by using:
echo "<IMG SRC=display.php/fakeoutinfobar.jpeg/pathame=$form_data_name>"
PHP and Apache will ignore that bogus fakeoutinfobar.jpeg in there, but infobar will probably see this URL as a JPEG and not output the HTML.

Hi Richard,
The system is not for any boxes use - it's for the user-access system I'm developing for my companie's Website. I copied the system they use at unix a little. We have READ and WRITE permissions and 4 different user-categories. 1,2,4,8 - the reason I'm splitting this up is actually quite simple, if I have a string like this
"1-2-8"
I can easier check if the user has the permission by checking whether "1" for example is inside the string. If I made the string look like this "128" it could easily be mistaken as a number...
I was trying to figure out a shorter way of achieving the same thing, since splitting up those numbers gave me (and my maths teacher) quite a headache at first :)) do you have any ideas?

I'm guessing you mean 3-D, since 2D is just there...
AFAIK, there's no built-in 3-D support to GD. You'd have to have a separate 3-D engine and a renderer to project it onto 2D before you ever touched the GD functions.
No idea what engines may or may not be available that you could interface to, or how.
If all else fails, look for a 3-D engine that has good command-line support, and use http://php.net/exec

Wild Hypothesis: Some worm/virus/hacker is trying to access: http://yoursite.com/something/something/../../whatever.php in the hopes of getting into something. Apache and PHP are getting confused, and end up spewing your HTML/PHP file into the log as source. (Which sure beats giving the hacker anything, eh?)

Sessions work by sending Cookies. Cookies work by being transmitted as "Headers" Headers are called headers because they come *BEFORE* any HTML. Example: --------------- What your browser *REALLY* sees: --------------- Content-type: text/html X-Powered-By: PHP-4.0.6 Content-length: 42
<HTML> <more html in here> </HTML> ----------------------------------------------------------------
That blank line in there is *CRITICAL*. Everything before that line is a header. Everything after that line is HTML, and *NOT* a header.
Once your script has sent out some HTML, or even a blank line, PHP can't suck them back in and send out a header.
Common Causes: A trailing "newline" at the end of your "include" files. Get rid of them. Adding your session code after your HTML and HEAD sections. Don't.
The session stuff and any header() or setcookie() calls *MUST* come first.
Another option is to turn on "Output Buffering" It will slow down stuff, because PHP will basically store all your output until it's complete, and then only send it at the end. But then it can stick headers in at any time you like.

I'm guessing one of these is line 222, and you have no record for that '$id' yet in your database.
For a brand new site, you'll need to register them first, or stick an in
front of these, or...
Or, just use your $numOfRows to decide if there's a value to retrieve or not.

Unless there's more to this function you are not showing, you could just do:
function updateHitCounter($id,$PHPSESSID,$type){ $flag=$this->validateSession($PHPSESSID); if($flag==1){ include("admin/config.inc.php"); $connection = mysql_connect("$host","$username","$password"); if ($connection == false){ echo mysql_errno().": ".mysql_error()."<BR>"; exit; } $query = "update sites set $type = $type + 1 where id = '$id'"; $update = mysql_query($query); } }

Things I know are wrong: 1. I don't think you want a - before the a-z 2. You have ()s around only the stuff *AFTER* the first character. So you are losing that stuff in the ()s to be saved in the third argument you're not providing to eregi()... 3. You didn't escape your \ from PHP, nor eregi(). You need \\\\, I think. 4.

The difference would only be measurable if you had a *LOT* of variables... Like, a whole lot.
Also, PHP *may* (for all I know) have to do more "work" to execute:
$string = substr($string, 0, 10);
than:
$foo = substr($string, 0, 10);
Dunno if it helps or hurts or has no effect for PHP to have to worry about where the string is going after it does substr, but it *MIGHT*.
At any rate -- The right way to worry about perforance is to figure out where your code is spending 90% of its time, and to optimize that. I'm betting it ain't in variable lookups for most of us :-)

Is there anyone here familiar with Audiogalaxy's site? It's all in PHP, and there is something there which is really something...
when you're searching for songs, there's an icon that when u click, it adds the song to the queue. But the page remains... the file is added to the queue without leaving your current page... and the icon changes color (this is easy with Js, but that's not the point)..
Does anyone know how they did that? ____________________________ . Christian Dechery (lemming) . http://www.tanamesa.com.br . Gaita-L Owner / Web Developer

When you click on the image it reloads the image which is really a PHP page which returns a image.
That way when it loads the image, it can actually run some PHP and do whatever is required, once done it returns the approiate image
That make sense?

Is mysql's PASSWORD() function secure for storing passwords?
Or should I use one of PHP's md5() or uniqid(), or even md5(uniqid()) ??? ____________________________ . Christian Dechery (lemming) . http://www.tanamesa.com.br . Gaita-L Owner / Web Developer

This is a repost.
To summarise: My installtion of PHP is unable to resolve names. I can't use fopen to open a URL which uses a name, but if I manually calculate the IP address, I can read in the page OK. ( see example below ).
I need some tips on where to start looking to solve this problem.
If it helps, my config options when I built PHP were:
--with-gd=/usr/local/src/gd-1.8.4/ --enable-gd-imgstrttf --with-ttf=/usr/local/freetype/ --enable-calendar --disable-short-tags --with-mysql=/usr/local/mysql/ --with-jpeg-dir=/usr/local/src/jpeg-6b/ --with-apxs=/usr/local/apache/bin/apxs
and I am running PHP 4.0.4pl1 under Debian "Potato" Linux and Apache 1.3

Hiya,
I was waiting for someone to answer this question but it hasn't happened yet. I was using this a couple years ago to get a weather page from http after the ftp site with the raw text disappeared. Rest assured this has NOTHING to do with php and everything to do with lynx.
I ran my script fine, then after I upgraded my system (I believe it was redhat 6.2) I started getting the error msg you got. After doing 'man lynx' and reading what I could, I gave up really fast and just reinstalled an older version of lynx cause let's face it, it was just a weather script that didn't warrant more than 20 minutes on.
The message is basically saying "Hey, you're running me from a cron job and I can't find an ncurses terminal to output to!" I am assuming that's what it is but don't quote me :) You may want to spend a little time in the lynx docs, and then let us know when you find out :) Also, I'm not 100% sure that the script itself isn't running.....try redirecting that from dev/null to writing to a file like /home/user/TEST.PHP and examine the contents.....

I am working on an image upload script and I've tried to use the variables from $HTTP_POST_FILES however it seems that no matter how I try to get the variables, they are always empty -- even though they are populated when checking phpinfo();
HTTP_POST_FILES["binFile"] Array ( [name] => arrow-block.gif [type] => image/gif [tmp_name] => /var/tmp/phph60272 [size] => 857 )
I got some info on it from php.net and attempt to echo as they have on their site however it displays nothing.
echo $HTTP_POST_FILES['binFile']['name']."<br>";
I am attempting to get size/extension of the file to determine if its a valid extension and within the valid filesize range.
Is this a server issue or just my php newbie-ness? If anyone has any ideas on how I can get this working, please let me know.
Thanks.
