Are there any recommended libraries or frameworks for handling file attachments in PHP emails?

When sending emails with file attachments in PHP, it is recommended to use a library or framework that simplifies the process. One popular library for handling file attachments in PHP emails is PHPMailer. PHPMailer provides easy-to-use methods for adding attachments to emails and ensures that the attachments are properly encoded and sent with the email.

<?php
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->Subject = 'Email with Attachment';
    $mail->Body = 'Please see the attached file.';

    $mail->addAttachment('path/to/file.pdf', 'filename.pdf');

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