PHP switch user ???

Hi there. Maybe this is a stupid question, i dunno, but untill now, nobody seemed to be able to answer it, so here goes. I have PHP4 running under apache as a DSO on a linux system. This is cool, it runs as nobody, and thus is fairly safe. But also very unfunctional when it comes to uploading files, manipulating and removing files :( Is there a way i can make PHP switch user for a while and then switch back ? I mean, like making it switch from nobody to the desired user, do stuff, when done, switch back to nobody ? I do not want to make folders/files world writeable etc. Thanks. -- - NoSpeed ------------------------------------------------------ - Carpe Noctem "The stickers on the side of the box said "Supported Platforms: Windows 98, Windows NT 4.0, Windows 2000 or better", so clearly Linux was a supported platform."
