v::filterVar(FILTER_VALIDATE_EMAIL)->validate('bob@example.com'); // true
v::filterVar(FILTER_VALIDATE_URL)->validate('http://example.com'); // true
v::filterVar(FILTER_VALIDATE_URL, FILTER_FLAG_PATH_REQUIRED)->validate('http://example.com'); // false
v::filterVar(FILTER_VALIDATE_URL, FILTER_FLAG_PATH_REQUIRED)->validate('http://example.com/path'); // true
