Date is a reserved word in Mysql. Also, that might work better, after
renaming the field from date, as
SELECT *, SUBSTRING(datefield,5,2) AS substring_date FROM $table ORDER BY
substring_date

Dear all,
I have a SSL server set up and I check in PHP that its running over SSL by doing:
if ($HTTPS) { ... }
This has worked for ages - but sometime last night the behaviour of my/our server changed and now over an non-SSL connection, $HTTPS = ON and over a SSL connection $HTTPS = on (note the change in case). This is odd - and I can't find the source.
Unfortunately I'm not the only one with admin access to the server - so someone may have changed something :(.
Anyone got any ideas? Where to start looking?
Thanks,

I can't remember what I did, but this happened to me as well. I have a check https function. I restarted apache and I think it worked. phpinfo still showed the $HTTPS variable but I could not use it inside a function even though I had it set as a global variable. Try restarting...

Hello everyone,
I've been tearing my hair out trying to write a function in PHP that will accomplish the following:
Given a multidimensional array with words as keys, I want to match the values of each array with the keys of the array and build a new array that reflects these relationships as a sort of tree. So, in the list below, "fruit", "apples", "oranges", "red" are the keys and in the "fruit" array are the values "apples" and "oranges", so I want the function to create a new array that looks like:
ORIGINAL ARRAY: $array['fruits'] = array("apples","oranges","pears"); $array['apples'] = array("red","granny smith"); $array['oranges'] = array('mandarin'); $array['red'] = array("big red","small red");
NEW ARRAY: $array['fruits'] = array(apples,oranges,pears); $array['fruits']['apples'] = array("red","granny smith"); $array['fruits']['oranges'] = array('mandarin');
And then I want it further to figure out that "red", now in the array found at: $array['fruits']['apples'] matches a key in the original array so the final result looks like:
FINAL ARRAY: $array['fruits'] = array(apples,oranges,pears); $array['fruits']['oranges'] = array('mandarin'); $array['fruits']['apples'] = array("red","granny smith"); $array['fruits']['apples']['red'] = array("big red","small red");
So, you see how it builds a little tree, right?
AND, I'd like this function to be able to handle any number (probably less that 30, but whatever) of initial array elements in an unpredictable order and the final tree could have up to five or six levels. You know?
Is this impossible, or am I just going about the end result wrong?? It seemed like such a simple thing three days ago, but now I am about to cry uncle.
Anyway, please write if you have any thoughts.
Best, Sondra Russell

If Cookies are off, you may need to provide more than just "#" as the HREF.
While "#" will "work", it's not technically speaking a valid URL, and PHP is probably not inserting the SID into the URL, or else inserting it in the "wrong" place.
Use "View Source" in your browser to see what PHP is doing to that HREF.

Well, since you're getting a PHP error, PHP is obviously parsing the page. My guess is that your error reporting (in php.ini, httpd.conf or .htaccess) is set very high, so that uninitialized variables generate a warning. You could either (1) initialize $page at the top of your program:
$page = false;
or (2) lower the warning level:
http://www.php.net/manual/en/features.error-handling.php http://www.php.net/manual/en/configuration.php http://www.php.net/manual/en/ref.errorfunc.php
If $page is coming from somewhere else (eg; GET/POST parameters) then you can test for its existence like so:
if (!isset($page)) { $page = false; }
or $page = 0...whatever's appropriate.

str_replace() is case-sensitive. If $results is returning a string like "Windows are nice" (it would help to see the actual string next time...hint hint), it won't match "window".

virtual doesn't return the content of the subrequest, it sends it to the browser.
you need to use something like popen() to do what you're trying to do.

Thanks dude, that looks way nicer. I did however get it working by changing the casting (tried to post my correction, but hit the wrong button), the corrected, and after Lynch's enlightening me on mktime´s behaviour even butt uglier code can be found below. (Change in arguments is solely due to a redesign of the form).
On a mere philosophical level I'd like to know how the original code could work on IE5, it's also got a dead obvious bug in the zeroPadDate() function (didn't set $mstr or $dstr when month>=10 or day>=10). And no, it wasn't due to using different arguments to the script on the different browsers...
Anyway, thanks! //Claes

The thread discussing the relative merits of mySQL and PostgreSQL have been very informative. I've been looking at the possibility of using FrontBase (http://www.frontbase.com/), primarily for its support of ACID and Unicode since I'm primarily working with Chinese, Japanese and Korean data. Moving from mySQL to FrontBase also seems to be relatively painless (although that isn't a consideration for me now choosing a database). Does anybody have good/bad experience working with FrontBase?

I note that the latest build of PHP4 comes with Japanese string support. Does this include support for two-byte regular expressions? If yes, does it also work with Chinese and Korean text? If no, what other options do I have without, for example, going through say JPerl or whatever?

mbstring module does not support multi-byte regex.
There is multi-byte encoding regular expression module called mbregex which is not a std PHP extension. It probably works with EUC-TW/EUC-KR.

I don't use it lately, but I think it comes with Japanese instruction only.

Either the PHP compilation itself is whack, or you typed something so unlike PHP script that you've *really* managed to confuse it...
Do other PHP scripts work?
What's your source look like?

You mean INITIALIZING. There are no variable declarations in PHP.
And, yes, it's a good idea so you're never surprised by a variable that you end up using twice.
> - Naming of include files - .inc or .php ? > - naming of class files .inc or .php ?
Name them .inc, *AND* move them outside the web tree if you can++, *AND* configure Apache to NEVER, EVER serve up an .inc file in any way, shape, or form.
++ The scale and scope of your project may require so many .inc files with the same names that you need to place them in the same directory as the PHP files that use them. Just be sure Apache won't serve them up.

I could be wrong in thinking this, but wasn't the purpose of the presented
function to shuffle a deck in a deliberately imperfecatly random way? ie.
mimicking a human shuffler.... beats why one would want to do this as an
academic excersize, but hey, I like it ;-)

Well, I required a function to mimick a human shuffle. Because the online shuffle was to help the user predict what sort/types of deals he would get with a given deck based upon a normal human shuffle.
Plus, I've heard some bad things about shuffle, and of course, shuffe doesn't mimick a non-perfect human shuffle.

First of all, you'll need:
php_value sendmail_path "/usr/sbin/sendmail -t"
Yes, you need the quotes. And possibly some other options inside quotes depending on your ISP's configuration of sendmail.
I don't understand your ISP's rationale for requiring you to do this in .htaccess instead of just doing it himself... Either he's letting you use mail() or he's not.
I also don't understand why you are loathe to do this... Unless you've heard ".htaccess is slow" (which it is). Alas, since your ISP has already turned on .htaccess support, you're *NOT* causing any additional significant slow-down to *utilize* the feature. The slowness is in Apache looking for the damn file, not in your putting (reasonable) stuff in it.
Oh yeah, to answer your original question :-)
You probably *COULD* set up an SMTP server on some other machine and just fsockopen() to that SMTP server and spew your emails to that. This will be way more faster anyway. Or, perhaps your ISP has an SMTP server that PHP can fsockopen() and spew to. Depends on how he configured it. There's all sorts of sample code for this SMTP spewing, so you needn't write it from scratch -- though it ain't rocket science. I did it, so it *CANNOT* be that difficult. :-)

unset() won't do anything because the *BROWSER* re-sends the username/password for that Realm when it gets the headers requiring them.
This continues until the user quits the browser, *OR* you stop authenticating for that Realm and start authenticating for another.
Thus, the way to "logout" is to maintain a dynamic unique dataset of "Realms" and require authentication in a new Realm for any user that is "logged out".

I'm integrating a telephony service into a clients site. I'm pretty handy with PHP but I don't have much knowledge of perl. I've setup up my client's site using PHP and the service provided me with a Perl script to make the telephone connection. I used virtual() in my PHP script to pass variables to the Perl script but now I need to deal with passing the results from the Perl back to PHP.
Is there something like virtual() in Perl that I could use to relay the variables back to my script? Can I call up the Perl variables from my PHP script after virtual()?
Any help would be appreciated.

There seems to be no reliable information in the manual about how to do this. I'm trying to use mcrypt 2.4 with php4.06, which should be a compatible combination.
So far, I have gotten it to work like this:
$cypher = MCRYPT_RIJNDAEL_128; $encrypted = mcrypt_encrypt($cypher, $key, $plaintext, MCRYPT_MODE_ECB); $decrypted = mcrypt_decrypt($cypher, $key, $encrypted, MCRYPT_MODE_ECB);
However, when I do this, I get an error saying:
Warning: attempt to use an empty IV, which is NOT recommend in
So I tried to do the same thing with an IV:
$iv = mcrypt_create_iv(mcrypt_get_iv_size($cypher, MCRYPT_MODE_ECB), MCRYPT_RANDOM);
and then added this $iv as an argument to encrypt and decrypt. At this point, it doesn't work, because the iv is different in the encrypt and decrypt functions, because it is randonly generated. Is it true that I need the same iv to encrypt as to decrypt? I'm just not understanding how to use this. All I want to do is to encrypt stuff and then decrypt it, using a key, right? It used to work.
Thanks.

hopefully someone who knows what they're doing can reply to you, but in the meantime this should get you going - it works for me:
$td = mcrypt_module_open(MCRYPT_TripleDES, "", MCRYPT_MODE_ECB, "/usr/lib/mcrypt-modes"); $iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($td), MCRYPT_RAND); mcrypt_generic_init($td, "your key string here", $iv);
then just use mdecrypt_generic($td, $data) and mcrypt_generic($td, $data) where $data is your string to encrypt

What part doesn't work?
$keyword[] = '$keyrow["fld_keyword_word"]';
would possibly be better without the single quotes, and I don't se where youe are calling the print_keywords function; which wouldn't work as is because it doesn't have access to the variable $mykeywords either from being passed as a parameter or made available as a global.
Also you misspelled $mykeywords in the function :-)

$mykeywords is a global var; it's undefined in the function's local scope. Either pass it into the function as a parameter, add it to the $GLOBALS array, or declare it as global within the function.

mysql_fetch_array only grabs the content of one row returned from a DB query, and puts it in an array - so your array here only has one element.

As above. You need to cycle through the results from the DB and add them all to the array.
But having said that, it seems to me that what you are really trying to do is to return unique entries from the database? In this case, look at using the DISTINCT keyword in your SQL query.

See if adding curly braces, {$array[1]}, doesn't work better for you.

That's an, er, interesting script. But it's not going ever to do what I think you expect it to.
You need to use while to loop through the rows returned by your SQL query, and for each iteration in the while loop, print the values you need. Also, if you use extract, you can directly access variables that have the same names as the rows in your table, so you don't have to refer to array elements.
Frinstance, if you are fetching fields named value and label for this exercise, something like:
echo '<FORM><SELECT>'; while ($array = mysql_fetch_array($mysql_result)) { extract($array); echo '<OPTION VALUE="' . $value . '">' . $label . '</OPTION>'; } echo '</SELECT></FORM>';
Of course, you'll need to put some more info in your <FORM> tag and add submit buttons and so forth.

Hi,
I have written a "Permission Converter" which converts unix permissions (the ones we know from CHMOD) into a "-" delimited string of numbers. I also made it that it supports one more level (unix only has 3 different types of permissions, (r,w,x) while mine can handle a fourth one. Since I'm just a newbie to PHP, I was wondering whether there is a shorter way of achieving the same thing. Here is my code:
// $num is the number (range: 1-15) $done = ""; $result = "";
while ($done != 1) {
if ($num > 8) { $num = $num - 8; $result = "8-"; } elseif ($num = 8) { $result = 8; $done = 1; } elseif ($num > 4) { $num = $num - 4; $result .= "4-"; } elseif ($num = 4) { $result .= 4; $done = 1; } elseif ($num > 2) { $result .= "2-1"; $done = 1; } elseif ($num = 2) { $result .= "2-"; $done = 1; } else { $result .= "1"; $done = 1; }
}
if ((strrpos($result, "-") = strlen($result)-1) && strlen($result) > 1) { $result = strrev($result); $result = substr($result, 1); $result = strrev($result); }
echo $result;

please hack apart this solution and point out the error/insecure nature of the setup.

Sufficient?
you end up with http://test1.com and http://test2.com being unable to create PHP scripts or do listings of any other virtual user directory since they are not of the same group, but accesses to the site are made by invoking apache as that group for that session.
directory tree drwxr-s--- 2 user1 user1 512 Aug 19 18:23 vtest1 drwxr-s--- 2 user2 user2 512 Aug 19 18:26 vtest2
with directory groups set in the httpd.conf for user1 in vtest1 and user2 in vtest2, neither user should be able to use PHP filesystem functions to browse the other directories as long as no public bits are set, and apache server requests still server the documents from the directories since each users directory has an Group user1 (or user2) set for his directory in the directory or virtual container, thus executing the apache requsts as the appropriate user and not the generic www user.
Please feel free to point out any errors in my logic... it appears pretty solid from here.
