Why is it recommended to use a library instead of the mail() function directly in PHP?

Using a library for sending emails in PHP is recommended over using the mail() function directly because libraries provide more robust features, better error handling, and support for various email services. Libraries like PHPMailer or Swift Mailer make it easier to send HTML emails, attachments, and handle SMTP authentication, making the process more secure and reliable. 

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

require 'vendor/autoload.php'; // Include PHPMailer autoload file

$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 of the email';
    $mail->Body = 'This is the HTML message body';

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