>what does posix_getlogin() return? perhaps you aren't really running the

posix_getlogin() return a empty string. However, the script is
definitely
running as root. The same script is creating directories in another user's
account using mkdir()

If the script UID is changed from root to the local user, the
mkdir fail
with a permission error. The script is also doing a copy() into another user's
file system which also fails if the UID is not room. Everything works except
chown() and as I said in the original post, the same back ticked
`chown abc data`; that works in a perl script in the same directory does not
work in a PHP script. I have also tried
system("chown egovdemo:nobody /fullpath/htdocs");

they don't have to be mysql/php specific, but that would of course help :)

general theory tutorials are fine too :)

A few questions:

At what level do you want the caching?
Are you talking about stored procedures?
Do you mean storing functions in the DB? (some DB's, like PostgreSQL can
compile functions once and reuse the compiled function).

Let me know where you want the caching to be and maybe I have a link or two.

attached mail follows:

Query caching is something that seems to exist in Cold Fusion, but not PHP.

What I'm referring to is that in Cold Fusion you can specify that query
results be cached in memory, and how long to cache those results. So, if
you have a page that runs the same query each time it's loaded, and you
cache a query on that page, then the results of that query are in memory, so
the call to the database is not run, instead the results from memory are
used, which can represent a HUGE speed increase.

To be totally repetitive, I'm not talking about a database cacheing results
of a query, but PHP caching the results of the query, instead of querying
the database.

I don't think it's possible to do anything like this in PHP, because of the
multiple database support, different function calls for different databases,
etc.

I've looked around, and found some PHP code that saves results sets in tmp
files, but I'm guessing that having the results cached in memory would be
faster than in files.

I think maybe the file caching was part of a database abstraction layer.

Don't run the htpasswd program at all, just write the .htpasswd file with PHP. The format is very simple, it's just username:crypted_password

So, you can just write those lines to the file, using the crypt function to create the crypted password.

Of course the same file permission issues exist that Evan pointed out (unless you're not in a shred environment, or are running PHP as cgi with Apache SuExe.), but those issues are for anything you do in PHP.

I have just started using xemacs as editor to my php scripts I think that the indentation in emacs stinks! xemacs has imorted a php package for med, but it does not make indentation on my html codes. <table> <tr> <td> </td> </tr> </table>

i would prefer looking like: <table> <tr> <td> </td> and so fourth.

Is there a way I can do this automatically? Now I do it by pressing space a lot of times. I hope there is a package I can import. Maybe there is some shortcut I can press where I want my tabbing to be, something like:

<table> [press short-cut here] [here I only need to press TAB to get the right indent]

Are there other nice editors for Linux RedHat?

Please help me. I really need it.

2. Splittable screen

3. Line numbering

4. A handy terminal emulator

5. Indent tracking, and brace tracking

6. Remembers recently opened files. I'll know what I've been working on.

7. Configurable tab spaces (I use 4 spaces)

Hi.

I am currently working on a projekt that will involve uploading files with filesizes up to about 10mb, and all sorts of different filetypes and I havet o Questsions concerning that.

1 ) How should the upload be done? I don't feel all that comfortable posting 10mb-files via a simple html-form, wouldn't that take a while if the connections is slow, and even if it was fast, it would take a minute or two. I was drawing out a upload functions with the built in ftp-functions, but then it occured to me, doesn't a <form> always posts it's content to the server anyway? How do I post large files without worrying about broken uploads, timeouts and all that?

2 ) How should I store the files? I suppose I have to optiones. Database ( I have mySQL installed ) or in folders ( in RedHat8.0 ) Should I build up a folder-structure to hold the files or just put it all in the database? A mySQL table in RedHat can hold 4gb, which is a lot, but my content may exceed that, how coud I check the size of the tables, and dynamically create new databases and when running a member Query, select content from them all? Would a file structure be better, with a folder strucuture for member a-b store in this folder c-d to in this and so on... Would it be stupid to store a 10000 10mb mpegs in one database?

Any suggestions?

Hi!

A client wants to test market two versions of an advertising but wants to disable the users' ability to copy/save the ads (right click, copy/save).

How can this be done in PHP?

It can't be done, period. You need to get the data to the browser for it to be displayed. Once it's on the user's browser a determined user will be able to save whatever it is that's being displayed.

This cannt be done in PHP. You would have to use something like Flash or Java - which is a lot of effort. The best you can do is disable right click using javascript, but that's easy to circumvent. Because everything's displayed client side, then a user could go into their Temporary Internet Files folder and find it in their anyway. Even using Flash or Java, if someone was determined to grab the individual images, then screenshots and an app to rebuild gifs would be easy to do. Unless of course they are full blown Flash ads, which would be harder to 'rip'. Why would a user want to save an advert anyway ? I don't believe I've ever saved an advert graphic - in fact I quite often resort to banner blocking, because some sites in particular go OTT on their use.

Not true -- you can use JavaScript to catch right-click events and do something creative with them, or disable them entirely.

But that, of course, is a client-side scripting issue, which has nothing to do with server-side languages such as PHP.

There is no client side solution. The only one I see is serverside: to put a text on the image, a bit transparent so that it does not affect very much the image but it can't be used.

Hi listers,

I have some webspace on a Unix server running apache. Things look like this there:

Path to dir with files - /home/username/public_html/ URL - www.somesite.net/~username

setcookie("id",$randval,time()+3600,"Q1","Q2",0);

What do I plug into Q1 and Q2? I want to set cookie for only my part of the site and not the whole site.

I have an ASCII file which has multiple blocks of text I want to clear. The scheme is as follows:

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- line 1 Everything between the separators, line 2 including the separators line 3 I want to clear from the text file line 4 -----------------------------------------------------

This text I want to keep

There are infinite number of blocks surrounded by exactly the same separators. So, I guess I need to clear everything between the starting "=" and the ending "-".

Can anyone suggest a regex pattern string that would help me accomplish that?

Thank you all guys in advance!

Hmmm... I was about to reply with a simple solution, but there's a problem with it that I can't explain. Assuming the text is in $str...

I can't get preg_replace to match a newline at the end of a pattern. If I use...

$str = preg_replace('/\n=.+--\n/sU', '', $str);

...it matches nothing, but if I put a tag character at the end of the dashes, e.g.

--------------------------------x

...then use... $str = preg_replace('/\n=.+--x/sU', '', $str);

...it works perfectly. I'm not sure why the pattern doesn't care about the first newline, but it chokes on the second one. Any thoughts?

If the separators are always the same length, then you can use the following:

$new_str = preg_replace("/(=-){5}(.*)-{10}/sU","",$str);

Where 5 is how many times the =- pattern repeats, and 10 is how many times the - character repeats.

Hope that helps.

Hello,

Does someone had a speed trouble when using PHP and Oracle with OCI ?? The trouble i have is that the php pages are slower and slower during the day. It looks that if I make an apache restart things restart in a good way. I don't understand where the trouble come from.

Help !

I've seen this once before and the cause was lots of phantom Oracle connections left open. So it wasn't PHP or Apache but connecting to the database which slowed things down. That may not be your problem but it's worth looking into...

Hi.

is their a possibilty to get the windows username of the current logged on user with php.

I want this to make a logon dialog more comfortable.

Thanks for an answer and a little example if it's possible.

Thomas

attached mail follows:

So, you want the server (PHP) to probe the client (user's) remote machine to find out the windows username?

Can't be done. First thing to remember is that PHP is server side. SOME LIMITED information is sent to the server by the browser, but I doubt this would ever be considered -- or even secure.

Second thing to remember is that not every user will be on a windows machine.

Some things can be achieved by client side scripts like javascript, but I honestly doubt you could do this, not would it be secure for the user.

Hi Thomas,

The following code should help you... Note that you have to turn off anonymous access in IIS, so that the user authenticates to a domain.

<? $ip = getenv("REMOTE_ADDR"); echo("IP address is $ip<BR>");

$user_chunks = explode("\\",strtoupper(getenv("REMOTE_USER"))); $user_domain = $user_chunks[0]; $user_name = $user_chunks[1];

echo("User domain is $user_domain<BR>"); echo("User name is $user_name<BR>"); ?>

Yes, it is strange. Something that might help you debug this out: - check server logs - turn off any output buffers - call flush() in your while loop - use another browser, IE is hiding stuff from users, but you are a developer, you need to know what is going on - check your loop if it is not endless - post some code

Hey guys,

I have a red hat 7.3 server running apache and php4. It all seems working fine, but when I try to upload a file through a form I got nothing. I mean, I can ouput the temp name of the file, the final name, size and other stuff. but some functions don´t work.

If (!is_executable($userfile_temp)) -> this don´t block executables files.

if I change to If (!is_executable($userfile_name)) -> it´s point me that all files is executable.

and when i try to move the file from /tmp directory to another directory with move_upload_file function. This func. doesn´t do anything, and doesn´t move the file to the specified directory

any help are welcome

None of the uploaded files is executable, even if it is some .exe or shell script, simply it does not have the permission to execute. $userfile_name is only the name of the file as it was on the client's machine, there is no such file on your filesystem (unless you create it)

i would use sessions in multiple hosts of my domain. say my domain is example.com, i'd use sessions in several hosts such as: www1.example.com www2.example.com www3.example.com

this could be easily configured in php.ini by putting: session.cookie_domain = example.com

but how can i do if i would EXCLUDE some hosts of my domain? someting like giving the exact list of hosts the cookie should be sent by user clients to the server: session.cookie_domain = www1.exclude.com,www2.example.com,www3.example.com (i tried, but it doesn't works!)

such thing is useful when you have some hosts in which you're sure you manage them, while some others you're not so sure. for istance, someone on an hosted site of the same domain could catch all sessions clients sent to his site and re-use those sessions faking someone other authentication...

some hints?

tell me if it's not clear...

bye, stain.

It is cookie restriction, you can - set several cookies, but it won't work if user has third party cookies disabled (many have) - pass session id in url if the url is cross domain

Hi all,

I'm aware that this post is borderline MySQL, but the solution may be more PHP-oriented, so I'm asking here first.

I have 4 related tables:

partner (id,name,url,desc) category (id,name) service (id,categoryid,name) pid_to_sid (pid,sid)

To point out the obvious, a partner provides one or more services, and a service belongs to a category.

However, the above table structure may not be the best solution, because I'm find that I need to perform MANY queries to get the information I need.

For example, to retrieve all 20 partners, with a list of the services they perform, broken into the 5 categories, requires heaps of queries:

while(partners loop of 20+ partners) { while(category loop of 5+ categories) { list services that match this cat and partner } }

Or, if I want to show tick boxes for all the services (broken by category) for a particular partner (say on an admin form):

while(category loop of 5) { while(all services loop of 30) { query DB to see if service is true for this partner } }

So, what I'm looking for is some missing snippet of code or information, or some little theory or tutorial that shows me the light on how I might reduce the number of queries, perform smarter, more complex queries, or something like that.

Otherwise, I can see myself writing some really sluggish code :)

Or perhaps my problem is back at the database level, with too many tables, or whatever.

attached mail follows:

// pseudo code (mostly) if (mysql_query("SELECT * FROM partner, category, service WHERE partner.id = service.id AND service.categoryid = category.id")) { while ($array = mysql_fetcharray($result)) { $partners[$array["id"][]= $array; } }

// then do ... foreach($partners as $services) { ... foreach($services as $service) { ... } }

this may not be quite what you need but you get the general idea. looks like services as effectively a many to many link table, nothing wrong with that as far as I can see

attached mail follows:

For me it seems it can be done with one mysql query: SELECT * FROM partner p LEFT JOIN pid_to_sid p2s ON p.id=p2s.pid LEFT JOIN service s ON p2s.sid=s.id LEFT JOIN category c ON s.categoryid=c.id WHERE $your_conditions ORDER BY p.name, c.name, s.name

The important part is ORDER BY clause, so when you retrieve the rows, by checking p.id and c.id to its previous ids, you find out you encountered next partner or category, respectively (if p.id has changed, c.id has changed too). LEFT JOINs are used so you get also partners not providing any service. You also use same column names in several tables, so instead of asterix use p.name AS partner_name and so on.

Hope this helps

Use nl2br(), something like:

echo '<textarea>', nl2br(htmlentities($string)), '</textarea>';

This should give you the results you need.

Did you type this from memory or paste it in? You have n\ instead of the backslash before the n. I think that

$string="-line1\n-line2\n-line3" ;

would give you the line breaks you want.

Hi there

yes , the shebang ( the #!/usr/local/bin/php ) is not needed for use with dynamic webpages wether they be perl , php or whatever

Shebangs are used only with shell based scripts. Your webserver should be configured to know what to do with the file by extension, e.g. .php files should be processed by php in apache

This link describes how to configure a webserver to do this

Hi Denis,

At the moment, if you view the HTML, you'll see:

Your browser sees this as an input with a value of "jane" and an attribute called "enterprises", which it doesn't recognise (and therefore ignores completely).

What you need to do is stick quotes round this, so it'll become:

We typically mkdir and put via ftp, but a browser interface isn't by any means impossible. You throw your pix on the server in any dir layout you want and then browse to the page and, voila!, the 'nails are made and the pages laid out and you can add comments and whatnot.

Care for a demo account to try it out? :-)

Yes, you'll use the $_FILES array to get to the uploaded file data.

Whether or not you can upload files is determined by the setting of 'file_uploads'. 'register_globals' has nothing to do with it.

I have just got use of a new dedicated webserver...

Now the 1st time a piece of code is ran it doesnt work but then the 2nd it does...

i.e.

index.php

// stuff... $visitDBID = referrerVisit($rid,$rgid,$visitIP,$visitFromURL); // stuff...

//end index.php

When it's ran initilly: the sql that i generated looks like:

insert into referral (RID, RGID, VisitorIP, VisitorDate, VisitorFromURL) values( insert into referral (RID, RGID, VisitorIP, VisitorDate, VisitorFromURL) values(Resource id #4,Resource id #4,'Resource id #4',NOW(),'Resource id #4') , insert into referral (RID, RGID, VisitorIP, VisitorDate, VisitorFromURL) values(Resource id #4,Resource id #4,'Resource id #4',NOW(),'Resource id #4') ,'

and gives the error:

Error: SQL: Error Code: 1065: Query was empty

However if i refresh the page: it executes correctly...

Any ideas?

I could do this in perl but I'm being stubborn :-)

When I run the following code as a regular user, everything fails. When I run it as root the directory is created and the chmod works. However, chown reports:

chown failed: Operation not permitted

Here is the code.

$Directory2Create = "/home/e-govdemo/htdocs"; mkdir($Directory2Create,0777); chown($Directory2Create,"egovdemo"); chmod($Directory2Create,0777);

"egovdemo" is a legal user name as can be seen from this partial directory listin.

egovdemo nobody 4096 Sep 6 11:29 Logs

also tried chown($Directory2Create,"egovdemo:nobody"); chown($Directory2Create,"637"); chown($Directory2Create,"637:99");

To help save my few reamining hairs and could someone with root privilege try it and see if it's me or PHP?

It works fine with PHP 4.2.2 from the command line run as root on my Linux system (using a user on my system) produced:

Running following as root using 4.3.0 CLI:

<?php

$Directory2Create = "/tmp/htdocs"; mkdir($Directory2Create,0777); chown($Directory2Create,"jason"); chmod($Directory2Create,0777);

#ls -al /tmp

chown() can only change user, use chgrp() to change the group!

Try it without quotes. It works for me.

Brent, et al --

...and then Brent Baisley said... % % I'm not sure how you are creating your array, but your resulting array

Well, here's some code with some commentary to perhaps help:

- first we define a name for a picture basket; the default is 'default' (we might later get a new name from the user or replace an existing basket and save the collection)

- we base64_encode the basket name (if it isn't already done) so that we can safely store it and use it as a key in the basket list

- so we're ready to populate $pixbasket, an array of values (path to picture) and keys (base64_encoded version of the value, in fact, for the same sorts of reasons); we're given a base64_encoded path as the picture to put in the basket:

if ( $fn == "add" || $fn == "rm" ) # are we adding or removing a pic? { ... $p = base64_decode($basketpic); # get the pic path ... case add: $pixbasket[$basketpic] = $p; break ; # add to basket ... }

- when it's time to save the basket, we put the whole array (as a value) onto the basket list array:

if ( $fn == "manage" ) # still? { ... if ( $basketsave && ( $newname || $target ) ) # what to do and how to do it? { if ( $newname ) { $basketname = base64_encode($newname) ; } # use this if we have it ... else { $basketname = $target ; } # ... or else use 'target' (already encoded) $basketlist[$basketname] = $pixbasket ; # put it in the array ... }

- then we write the whole basket list array to a file and get it back some other day

% would look something like this: % % Array % ( % [name1]=>namevalue1 % [a1]=>Array % ( % [k1]=>value1 % [k2]=>value2 % ) % [name2]=>namevalue2 % [a2]=>Array % (...

Hmmm...

% % You end up with a two dimensional array (avoiding the columns term) that % contains a name value and a values array for each entry.

OK. I was able to construct this directly, but I don't see how to use it; if I ask for array_keys() for the outer array I'll get both types of keys and that would be a mess.

I suppose I could have another array like

$names = array ('name1', 'name2', 'name3') ;

where I maintain the order (renaming 'name2' is as simple as

$names[1] = 'newname' ;

once I determine that I'm working with position 1) and then have my array of baskets, now simply by ID instead of like a hash, so

$baskets = array (array(...),array(...),...) ;

would work) and then wrap both of those into the single array for writing (like

$basketlist = array($names,$baskets) ;

or so), but that seems even more of a kludge :-)

Given the array you present above, how would you extract a basket by name? The closest I can come is to go and find the name and then increment the ID by 1 and then get out that basket, which sounds like a *huge* mess...

Thanks again & HAND

Unless the user has a lot of baskets, I would assume you would just list all the baskets the user has as links on the web page or as a pop up menu. The value passed by the links or pop up would be the element number of the array item containing the desired basket. To extract a basket by name I would say you could use array_search, but in looking into that function it appears to have changed through recent versions of PHP. In PHP 4.1 it doesn't search multi-dimensional arrays, I'm not sure about in 4.2.

But it's easy enough to create your own function to search the array. And you are right, the setup I recommended can get a bit kludgy. But if you "denormalize" the array structure it can get easy again. Just make the first element for each basket the name of basket. $baskets[] = array("basketname1","item1","item2"); $baskets[] = array("basketname2","item1","item2","item3"); $baskets[] = array("basketname3","item1","item2",...);

You can use sort() to sort the array.

Hope that helps and sorry about steering you down the difficult path first.

If you are looking for something as simple as an index or key rename function it can be done and without making any copies of the array or object etc by:

$array['new_key_name'] =& $array['old_key_name']; unset($array['old_key_name'];

The first line creates a reference to the array. The second line removes the first reference without removing the second.

One never knows, but I currently list as many as he has anyway.

% menu. The value passed by the links or pop up would be the element % number of the array item containing the desired basket.

OK... Then, of course, I'd have to do name->number mapping so that I can present the surfer with the name that he chose rather than just a number, but that could be done, too.

That was it, indeed, but

$t = array("t1" => "temp1", "t2" => "temp2" ) ; $f = array("f1" => "foo1", "f2" => "foo2" ) ; $a['t'] = $t ; $a['f'] = $f ; $a['n'] =& $a['t'] ; unset($a['t']) ; print_r($a) ;

yields

Array ( [f] => Array ( [f1] => foo1 [f2] => foo2 ) [n] => Array ( [t1] => temp1 [t2] => temp2 ) )

instead of having 'n' before 'f' (in the old 't' spot) as desired.

So I'm back to the beginning and to funky array wrappers again... I think these surfers will just see their baskets in different order after a rename :-)

Of course, if you display the baskets in alpha order by name, it won't be too much of a shock to them when they are displayed in a different order after rename. :p Just a through.

I have a site with a PHP auto-mailer where the owner of the site gets a report generated from the DB, it all works fine, except his server has spam filtering enabled so the FROM header in my PHP-Generated email, which says "apachehostname" doesn't work because what the hostname is set to, isn't resolveable outside our network. Now I know I can just set the servers hostname to a valid DNS name, but this brings up another problem, even though I'm manually setting the "From" and "Reply-to" headers in the PHP mail command (the last parameter), when the email's are listed in his box, it works, if you open the headers in the email near the very top it still says "From: apachehostname" and a little ways below it says the From and Reply-to I set.

So, is there anyway to override the top From which says apachehostname? Maybe setting additional parameters on my sendmail command line in the php.ini? Any ideas? I appreciate it.

Hi!

I'm wondering is, is there a way to lose the existing session and existing session data while making a new session id??? I can't use session_destroy() function because it affected IE users, it doesn't affect the non-IE user at all. I got so tired of problems with IE and having it to work properly with the session id, so I decided not to use session_destory().

So, a case situation here is when an IE user closed the browser without logging out. Then later on, fire-up the browser and log in. Problem with this is when I create a new session_id(), it should work but for some reason, a couple of IE users are being affected because the original user did not log out in the first place. So, I decided not to use session_destroy() because of some strange relation between many IEs and the PHP session_id. So, is there a way to detach any existing session data then creating a new session id when logging in???

Thanks!!!

Sounds like you have a problem in your code logic, not in how PHP handles sessions. Whether someone logs off or not shouldn't affect other people.

When a session is closed, even though the file in /tmp may still exist, it is simply waiting for garbage collection to clean it up.

I've got a site running PHP w/ MySQL & DBF extensions on Apache with mod_ssl/openssl.

Yesterday, following upgrading to 4.3.0 (and upgrading mod_ssl/apache as well) the site stopped working. I quickly figured out there was a change in session processing and that I needed to no longer use global variables to transfer information from my $_POST array into $_SESSION but that I needed to transfer the information directly.

After making this change I was able to get rid of the warning messages and things started looking like they were working correctly but the results of the queries didn't respond consistently. In fact, if I run the same query 10 times I'm likely to get 3 different kinds of results. No records found (which is false), a "Page Not Found" error (also false), and about 15% of the time I'll get the correct results.

I've tried setting the PHP.INI settings for the compatibility and warning in all 4 different combinations and I've even turned register_globals back on to see if that would solve it ...

This was a live e-commerce site until I upgraded and now my client, his customers and my rep are going down the tubes ...

Help please someone!

Bob.

You have the image data in a string, right? Could you relate the length of that string to the resulting size of the file, somehow?

After calling the funtion ImageCreateFromJPEG like this: $im = ImageCreateFromJPEG(pic.jpg); then $im is not a string but a resource. I don't know how to get it into a string.... Olli

Use output buffer: ob_start(); ImageJPEG($im); $imagestring=ob_get_contents(); ob_end_clean();

Thanks for the answer. But if I do it like that, the picture has been sent to the browser. That's what I don't want. I need to know the size of the picture before it is sent to the browser. Olli

attached mail follows:

No, it's not sent to the browser. Your output buffer catches it, and the output buffer is then erased with ob_end_clean().

Is that above function relevant? You've defined it but it's not being used in the code below?

> $i = 0; > do{ > ldapConnect($config['ldapServer'][$i]); > $i++; > }while(!$ds && ($i < (count($config['ldapServer']) + 1)));

Anyway you can try something like:

foreach ($config['ldapServer'] as $key => $value) { if (ldapConnect($value)) { // if successfully connected $server = $value; break; } } echo "Connected to server $server";

Untested, but this should work.

$numOfWords = count( explode( " ", $string ));

To be somewhat more rigorous, you could do:

$numOfWords = count(preg_split('/\s+/', trim($string)));

(also untested); this ignores leading/trailing whitespace, and deals with multiple spaces/tabs between words. There is an example in the docs (below) called 'Get the parts of a search string' that shows how to add other characters that you might consider valid word delimiters - eg, a comma.

See http://php.he.net/manual/en/function.preg-split.php

I don't think spaces are legal in variable names - PHP's probably just trying to recover from the dodgy data it's getting.

That's just what PHP does. It'll also convert any periods in a form element name to an underscore.

Otherwise, if you have register globals on, it would try to create a variable of "$aa bb" which doesn't make sense, or "$aa.bb" which doesn't make sense, either, because the dot is a concatinator.
