Are there any specific PHP libraries or classes recommended for sending emails instead of using the mail() function?

Using the mail() function in PHP to send emails can be unreliable and lacks features such as attachments, HTML content, and proper error handling. It is recommended to use a library like PHPMailer or Swift Mailer for sending emails in PHP. These libraries provide a more robust and feature-rich solution for sending emails securely and efficiently.

// Example using PHPMailer library to send an email
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

$mail = new PHPMailer(true);

try {
    $mail->isSMTP();
    $mail->Host = 'smtp.example.com';
    $mail->SMTPAuth = true;
    $mail->Username = 'your@example.com';
    $mail->Password = 'your_password';
    $mail->SMTPSecure = 'tls';
    $mail->Port = 587;

    $mail->setFrom('from@example.com', 'Your Name');
    $mail->addAddress('recipient@example.com', 'Recipient Name');

    $mail->isHTML(true);
    $mail->Subject = 'Subject Here';
    $mail->Body = 'Body Here';

    $mail->send();
    echo 'Email sent successfully';
} catch (Exception $e) {
    echo 'Message could not be sent. Mailer Error: ', $mail->ErrorInfo;
}
