Dear S.
           if you are posting this kind of question often, you may well 
be puzzled by the reply RTFM. It's not a polite response. It stands for 
'Read The F**king Manual'. To give you the benefit of the doubt though, 
you can find the PHP manual at
http://www.php.net/
Search for setuid in the function list.
I'm not quite sure about your other question. As an Apache module PHP 
runs as user 'nobody'...
