I put memory_limit = 50M into the php.ini and it didn't affect the phpinfo file.

I suppose i'll have to recompile?

no, you should just have to restart apache for it to take effect..

Bob, there is NO need to restart, if local override is allowed, it's on the fly.

ah, gotcha.. makes perfect sense :)

Yea, you wouldn't want to restart apache 300 times a day because ppl keep changing variables.

Depending on how you use PHP - if it's the Apache module a simple:

Should do it. If you run it as CGI / FastCGI just remove the Handler for the specific sub-domains or directories.
Little bit :confused: first allowing this handler to be executed - if it's CGI - just to run PHP in order the PHP interpreter gets it isn't allowed to do anything - so better remove it completely that there're no CGI / FastCGI calls made anyways.

Where do I put that Angel?
In php.ini or in htaccess? :confused:

Webserver Configuration if you're using Apache. For Nginx / Lighty or other server just look how PHP is called - usually via FastCGI then - and remove the handler / caller on your virtual hosts where you don't want to have them.

This is usually located in /etc/apache2/httpd.conf

I'm not sure for cPanel, I do not use it for years. Using Kloxo (formerly LxAdmin) and Virtualmin.

However, if you have root access to cPanel, all config files are editable from within WHM.

cpanel: /usr/local/apache/conf/httpd.conf
