I would probably have just returned a new array. Does it matter? Is one way more efficient or better, or not? http://codeassembly.com/How-to-sanitize-your-php-input/#264 2009-09-10 15:29:10 http://codeassembly.com/How-to-sanitize-your-php-input/#264 John Smith What would be the best way to add sanitisation for email addresses to this code? http://codeassembly.com/How-to-sanitize-your-php-input/#87 2008-03-08 14:16:53 http://codeassembly.com/How-to-sanitize-your-php-input/#87 Phil It would be nice to add a check for valid email address something like... 

function validate_email_address ($address)
{
	// check address format
	$address = stripslashes($address);
	if (!ereg ("^.+@.+\\\\..+$", $address) || empty ($address)) return FALSE;
	if (eregi ("\\r", $address) || eregi ("\\n", $address)) return FALSE;

	// safe
	return TRUE;
}
