What are the benefits of using filter_var() for email validation compared to regex in PHP?

Using filter_var() for email validation in PHP is beneficial compared to regex because it provides a simpler and more reliable way to validate email addresses. Filter_var() has a built-in filter specifically designed for email validation, making it easier to implement and less prone to errors compared to writing a custom regex pattern. Additionally, filter_var() is a native PHP function, so it is likely to be more optimized and efficient than a custom regex pattern. 

$email = "example@example.com";

if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
    echo "Valid email address";
} else {
    echo "Invalid email address";
}
