Remove irregular characters

[BillyConnite]

Hi all,

Just a small simple snippet to return whether or not irregular characters (anything not on your keyboard) have been used in a string.

Very useful for rejecting international characters (Generally from bots, SPAM!). I use it to reduce spam for the registration process in my forum hosting system.

	function isRegular($string)
	{
		return !preg_match('/[^A-Za-z0-9\s~`!@#$%^&*()-_=+{}:";\'<>?,.\/]/', $string);
	}

Hope someone finds it useful... Thank god for regular expressions.

If there is a more optimized way to match regular characters only, i'd love to know!

-Rhett.
