What are the advantages of using filter_var for email validation in PHP compared to other methods?

Using filter_var for email validation in PHP is advantageous because it provides a simple and reliable way to validate email addresses. It checks if the given value is a valid email address according to the RFC 822 standard. This function also allows for additional options such as filtering for specific types of emails (e.g., FILTER_VALIDATE_EMAIL for standard email addresses).

$email = "example@example.com";

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