So, are we to guess what you have done so far? Or, will you enlighten us by providing us with what you have done so far?

If this is for validation of emails, then a simple and effective solution would be to utilize filter_var.

$email = 'bob@example.com';

function validEmail($email) {
    return filter_var($email, FILTER_VALIDATE_EMAIL);
}

if (!validEmail($email)) {
    echo "The email address provided is not valid";
}
