Thanks Very much I used,
preg_match('/[[:punct:]]/', $_POST['username']) !== 0
and it works without errors. The reason I can't just use
is_file which I wish I could is because windows doesn't allow question marks
or some wierd character. It decides to not allow php to make the file if there
are odd ball characters. It is a very unfortunate mistake in my code that I
wish php would ignore and just make the file "?".
