“exec() has been disabled for security reasons” & “Undefined variable”

Question

I found a cool MySQL backup script. It\'s working fine on some hosting companies. Now I\'m trying it on a different host running PHP Version 5.2.8.

I have a php.ini fi

Answer 1

Many hosts disable certain functions, and do not allow overriding them in custom php.ini's (just because PHP offers the ability to have a custom php.ini, does not mean that all PHP setups are necessarily configured to allow you to change that option via such).

Chances are that host simply doesn't allow exec() period. Not much you can really do about that.
