How can using a Mailer class in PHP improve the process of sending email attachments?

Using a Mailer class in PHP can improve the process of sending email attachments by abstracting the email sending functionality into a reusable and organized class. This allows for easier management of email sending tasks, including adding attachments, without having to rewrite the code for each email sent. 

// Example of using a Mailer class to send an email with attachments

class Mailer {
    public function sendEmailWithAttachments($to, $subject, $message, $attachments) {
        $headers = "From: sender@example.com\r\n";
        $headers .= "MIME-Version: 1.0\r\n";
        $headers .= "Content-Type: multipart/mixed; boundary=\"boundary\"\r\n";

        $body = "--boundary\r\n";
        $body .= "Content-Type: text/plain; charset=\"utf-8\"\r\n";
        $body .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
        $body .= $message . "\r\n";

        foreach ($attachments as $attachment) {
            $file = file_get_contents($attachment);
            $body .= "--boundary\r\n";
            $body .= "Content-Type: application/octet-stream; name=\"" . basename($attachment) . "\"\r\n";
            $body .= "Content-Transfer-Encoding: base64\r\n";
            $body .= "Content-Disposition: attachment; filename=\"" . basename($attachment) . "\"\r\n\r\n";
            $body .= chunk_split(base64_encode($file)) . "\r\n";
        }

        $body .= "--boundary--";

        return mail($to, $subject, $body, $headers);
    }
}

// Usage
$mailer = new Mailer();
$to = "recipient@example.com";
$subject = "Email with attachments";
$message = "This email contains attachments.";
$attachments = ["file1.txt", "file2.pdf"];

$mailer->sendEmailWithAttachments($to, $subject, $message, $attachments);
