Title: PHP doesn't execute
Post by: Kees Vonk on June 02, 2003, 02:09:05 PM

I have installed a SME 5.6 server for someone, which generally works great. However we cannot get PHP scripts to execute, every time we access a page which contains PHP (and has a .php extension) in the html directory we get a blank page. If we move the php page to cgi-bin we get a '500 Internal Server Error' and the httpd error_log says:

[Fri May 30 09:54:03 2003] [error] (13)Permission denied: exec of /home/e-smith/files/ibays/website/cgi-bin/phpindex.php failed
[Fri May 30 09:54:03 2003] [error] [client 10.1.2.67] Premature end of script headers: /home/e-smith/files/ibays/website/cgi-bin/phpindex.php


PHP is enabled in the ibays setup, we have PHPMyAdmin running without any problems and yet I cannot get php to execute in a normal ibay.

I have never done this before and do not know a lot about php so this is probably just something silly, but any help would be greatly appreciated.

Paste me your PHP code if you would, you have to be sure to include the PHP delimeters ;

Also, try a simple script like:
[Contents of test.php]

[EOF]

Additionally, PHP may be working but you may have an error and may have display_errors turned off in /etc/php.ini, hence the blank page with nothing but header information.

Try turning error debugging on in /etc/php.ini (display_errors on), restarting httpd (/etc/rc.d/init.d/httpd restart), and accessing the page again.  You won't be able to execute php scripts in cgi-bin, so don't bother trying there.

Hope this helped,
Nathan

Thank you,

the test.php worked straight away, so I then set display_errors to 'on' and up popped the error I was looking for (it now also appears in the syslog which it didn't do before).

One more question though, is it possible to set display_errors for an individual website (ie. set the global default to 'off' and then change it for the one ibay)?

Thank you very much,

Kees

I'm very happy I was able to help you, I know how frustrating that stuff can be. ;)

I think you can use ini_set to set this value for a particular site upon execution of the PHP code.

http://us2.php.net/manual/en/function.ini-set.php

IE:

//Get previous value.
$prev_value = ini_get("display_errors");

//Set the value
ini_set("display_errors","1");

//Do some of your code here
//Blah blah, code code

//Set the value back to it's original
ini_set("display_errors",$prev_value);

?>

Note, on the bottom of the page under user comments this user says (but I've not yet validated it):

There is another possibility by changing PHP Settings!

If your Webspace is able to handle ".htaccess" files, you're able to change PHP_INI Settings through this file!

To disable register_globals you have to set:
php_value register_globals 0

If you wanna set other settings, feel free, because there is no problem!

These Settings are set before running the script, e.g. the results of register_globals, when setting a parameter in the URL like 'foo.php?foo=stuff', is not present, $foo is unset.

Thank you Nathan,

the .htaccess thingy works, thank you very much for all your help. I wish I got this level of support everywhere.

Behold the power of an open source community willing to help ;)

I'm glad everything is working great, now you can pass your expertise along to someone else with the same problem.

Thanks,
