Different php.ini for each user on same server

Is it possible to define a different php.ini for each user which use the same server, either Unix and Windows. Let me give you example what I mean: User 1 (professional PHP-user) Allow him big uploads, long execution time etc. Virtual directory www.user1.com User 2 (amateur PHP-user) Allow smal uploads, short execution time etc. Virtual directory www.user2.com Thanks, Sumarlidi E.
