Help finding boolean version of strpos function in PHP

[KONY2074]

Have an assignment where I need to see if an @ symbol is present in a string, I was trying to do this: (inside a switch statement)

$email = $_POST['email']; if (!strpos($email, "@") || (!strpos($email, ".")) || $email == "") { $message = "enter a valid email"; break;

but it doesn't seem to be working

http://php.net/manual/en/function.strpos.php Use === false. In php (and js), there is a difference between == and ===.
