You may want to look into shell_exec, which executes a command and returns
the output. If you're accepting arguments from user input, don't forget
proper use of escapeshellcmd and escapeshellarg ;-).
Something else that might cause your commands from failing, is that the
utilities are not inside apache's PATH - trying to call them by there
absolute filename can help out. Have you inspected your error_log? There
often tends to be a lot of useful stuff in there.
Good luck!
