[SOLVED] Internal 500 Error when using ini_set

Flowsen · 09-12-2011, 05:33 AM

Hi there,

I am using Debian Lenny with PHP 5.3.8 with fastCGI and Apache 2.2.9-10+lenny11.
Everything seems to work smoth except all PHP scripts where ini_set() is used cause a 500 error. For example:

ini_set("memory_limit","24MB");

no matter which memory size I use.
Any idea?

Kind Regards
Florian

A guess, but try removing the B ... "48M", etc.

+1

Yes, not my thing, but looks like a simple syntax error. Regardless it's not really a debian problem, you should ask for this to be moved maybe the "Linux - Server" forum.

Thats also what i guessed. I already tried everything:
ini_set("memory_limit","48M");
ini_set("memory_limit","48");
ini_set("memory_limit",48);

No matter what i try, I immediately get the 500 error.
I am sure that it has nothing to do with the PHP script itself because it is working if i leave the ini_set away (indeed i need it so thats not a soloution ;-)

btw ini_set("max_execution_time", "60"); works and does not throw an 500 error so i am really not sure what it could be.

I have to say, that the problem appeared after upgrading Apache and PHP from 5.2.x to 5.3.8.

PS: sorry for posting in the wrong place. I thought the right place is the debian forum as I am using debian lenny. So I would appreciate if a moderator could move my thread - thanks :-)

Is there anything in /var/log/apache2/error.log that would help?

NP, moved it to the Linux Software forum to help your thread/question get the exposure it deserves.

Furthermore syslog shows:

Thats the only message i get. Any way to extend this error message? I already looked into other log files without success.

I just wanted to inform you that I solved the problem.

The reason is that suhosin memory limit may not exceed 2047M.
Please dont ask me if this is a bug or not but if i keep in range up to 2047M setting memory limit in php.ini, .htaccess, PHP etc. everything works like a charm.
