I don't think you want || here -- The operator precedence of = and || and
OR are what's biting you in the butt, almost for sure.
echo "fh is $fh<hr />\n";
If that doesn't print out "Resource #1" (or some other number) then you've
got it wrong, and you might as well ignore the rest of this script until
it's right.
Also, it's probably REALLY BAD SECURITY that the PHP user can write (r+) a
file inside your DOCUMENT_ROOT!!!
Move the file somewhere else, outside the web tree, and give yourself a
config file to set the path for easy changing/installing.

Dunno what the 0 && is about, but it don't belong there when you're done,
of course...
