Re:

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 "?".
