I disable a lot of functions (including exec) in the php.ini file. Though, some websites on my server DO require the exec function. For example, some galleries require the netPBM binaries to create thumbnails, etc. Is there ANY way to enable the exec function for certain websites? I tried to use httpd.conf to override the disable_functions rule set in the core php.ini file but it just doesn't work. According to php.net, disable_functions can only be set in the core php.ini file and it's not possible to override it. Isn't there another way? I want to secure my server by disabling this function for most websites, but it should still work for those who actually need it.
