Are there recommended PHP libraries or classes for handling email sending tasks, such as PHPMailer or Swift Mailer?

When sending emails in PHP, it is recommended to use libraries like PHPMailer or Swift Mailer. These libraries provide a more secure and reliable way to send emails, handle attachments, and manage SMTP settings. By using these libraries, you can ensure that your emails are delivered successfully and avoid common pitfalls associated with manual email sending.

// Using PHPMailer 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 = 'yourpassword';
    $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';
    $mail->Body = 'Email body';

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