Are there any specific PHP functions or libraries recommended for robust email validation in web development projects?

Validating email addresses in web development projects is crucial to ensure data integrity and security. One recommended approach is to use PHP's built-in filter_var function with the FILTER_VALIDATE_EMAIL filter option. This function checks if a given value is a valid email address according to the specified format. 

$email = "example@example.com";

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