What alternative methods or libraries can be used for email validation in PHP?

One alternative method for email validation in PHP is to use regular expressions to check if the email address follows the correct format. This can be achieved by using the preg_match function with a specific regular expression pattern that matches valid email addresses. Another option is to use a library like PHPMailer, which not only validates email addresses but also provides functionality for sending emails. 

$email = "example@example.com";

// Using regular expression for email validation
if (preg_match('/^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/', $email)) {
    echo "Email is valid";
} else {
    echo "Email is invalid";
}

// Using PHPMailer library for email validation
require 'PHPMailer/PHPMailer.php';
require 'PHPMailer/Exception.php';

use PHPMailer\PHPMailer\PHPMailer;

$mail = new PHPMailer();
if ($mail->validateAddress($email)) {
    echo "Email is valid";
} else {
    echo "Email is invalid";
}
