note 93824 added to function.preg-match

As I wasted lots of time finding a REAL regex for URLs and resulted in building it on my own, I now have found one, that seems to work for all kinds of urls: <?php $regex = "((https?|ftp)\:\/\/)?"; // SCHEME $regex .= "([a-z0-9+!*(),;?&=\$_.-]+(\:[a-z0-9+!*(),;?&=\$_.-]+)?@)?"; // User and Pass $regex .= "([a-z0-9-.]*)\.([a-z]{2,3})"; // Host or IP $regex .= "(\:[0-9]{2,5})?"; // Port $regex .= "(\/([a-z0-9+\$_-]\.?)+)*\/?"; // Path $regex .= "(\?[a-z+&\$_.-][a-z0-9;:@&%=+\/\$_.-]*)?"; // GET Query $regex .= "(#[a-z_.-][a-z0-9+\$_.-]*)?"; // Anchor ?> If someone discovers URLs that don't match, please let me know.
