Preg Match Issues in validation email id

Why code below returns emails ID as false or invalid?

<?php
    $okay = preg_match(
        '/^[A-z0-9_\-]+[@][A-z0-9_\-]+([.][A-z0-9_\-]+)+[A-z.]{2,4}$/', 
        "[email protected]"
    );
    echo $okay;
?>

There already is a function from PHP itself to validate emails, I suggest using that instead of a regex.

<?php
    $email_a = '[email protected]';
    $email_b = 'Random words';

    if (filter_var($email_a, FILTER_VALIDATE_EMAIL)) {
        echo "This ($email_a) email address is considered valid.";
    }
    if (filter_var($email_b, FILTER_VALIDATE_EMAIL)) {
        echo "This ($email_b) email address is considered valid.";
    }
?>
