用php从shell启动sudo

Question

如何从PHP运行此程序？

sudo /etc/init.d/apache2 restart

Answer 1

I don't think that's a good idea.

Also, have a look to the following discussions:

Answer 2

You can use the exec command. http://ch.php.net/manual/en/function.exec.php

If you want to use sudo, just add the user Apache is running under (usually www) in the /etc/sudoers file.
