database — RSS

Okay, I'm having a bit of a problem here... I'm trying to create an RSS feed from my MySQL database. Unfortunately though, I can't seem to write to a file. PHP isn't running in safe mode, and the enclosing folder permissions don't seem to make a difference. The file gets created, but no writing occurs, and if the 'is_writeable' statement is taken out, the script runs until it times out and gives an error 500. Anyone have any clues?
