NYCPHP Meetup

I had this problem quite a few months ago. I don't remember what exactly
causes the problem, but I remember the solution was that I was forced to
write the file to disk, and then open it back up and shoot it out.

A similar problem occurs with mod_rewrite and IE6 from a bug thats been
in IE6 for > 2 years. They are pretty lazy when it comes to fixing stuff
like this.

Anyway, try writing the file to disk first and see if that helps.
