PHP - changing ownership of a process while running

I have a PHP script that I need to run as root from the command line.

After the script completes some critical operations (that require root acce开发者_如何转开发ss) I would like to change the owner of the process to 'nobody'.

Is that possible with PHP? How can I do it?

You can change user/group ids with the following functions:

posix_setgid

posix_setuid

posix_setegid

posix_seteuid

If you need to change the group, you'll want to perform that first.

No, script cannot change ownership explicitly to root.
