Are there simpler alternatives to the complex validation method shown in the forum thread?

The issue with the complex validation method shown in the forum thread is that it is overly complicated and difficult to maintain. A simpler alternative would be to use PHP's built-in filter_var function along with the FILTER_VALIDATE_EMAIL flag to validate email addresses. 

$email = "example@example.com";

if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
    echo "Email is valid";
} else {
    echo "Email is invalid";
}
