RE: [PHP] Getting gibberish, sometimes, in PDF output

Well could be several things from my experience.. if you leave off the trailing empty header(""); or a \n at the end of the last header it could cause your problem. The other problem I have had is when I put a session_start() after any of my headers in my code. The session_start() must be the first thing executed before all headers are processed... That is if you are using sessions like that.
