Be careful how you test for errors from fopen(). The familiar construction:
$out=fopen("file","w") || die ("file won't open");
is a great way NOT to create a working filehandle. Test instead with an if as in the note above.
The || has the effect of overwriting the filehandle and rendering it useless.

editors note: use 'or' instead of '||'
