What are the advantages of using a Mailer class over the mail() function in PHP?

Using a Mailer class over the mail() function in PHP offers several advantages, such as better encapsulation of email functionality, easier configuration of SMTP settings, support for attachments and HTML emails, and improved error handling. By using a Mailer class, you can also easily switch between different email providers or services without having to modify your code extensively. 

// Example of using a Mailer class to send an email
require_once 'vendor/autoload.php'; // Include the Mailer class library

use Mailer\Mailer;

// Initialize the Mailer class with SMTP settings
$mailer = new Mailer('smtp.example.com', 'username', 'password');

// Compose the email
$mailer->setFrom('sender@example.com', 'Sender Name');
$mailer->addTo('recipient@example.com', 'Recipient Name');
$mailer->setSubject('Test Email');
$mailer->setBody('This is a test email sent using a Mailer class.');

// Add an attachment
$mailer->addAttachment('path/to/file.pdf');

// Send the email
if ($mailer->send()) {
    echo 'Email sent successfully';
} else {
    echo 'Failed to send email';
}
