phone() public static method

It is not a strict rule and should cover almost all legal phone numbers. Some (obviously) illegal phone numbers will pass this test, especially cellphone. Since it will be a hard task to maintain a small cellphone prefix "database", just make it simple for now.
public static phone ( string $check ) : boolean
$check string The value to check.
return boolean Success.
