What are some best practices for handling attachments in PHP emails, especially when they are not images like PDF files?

When handling attachments in PHP emails, especially non-image files like PDFs, it's important to properly encode the file content and set the appropriate headers for the email. One common method is to use the PHPMailer library, which simplifies the process of adding attachments to emails. By using PHPMailer, you can easily attach files of various types, including PDFs, and ensure they are correctly encoded and sent with the email. 

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

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

// Create a new PHPMailer instance
$mail = new PHPMailer(true);

// Set up the email details
$mail->isMail();
$mail->setFrom('from@example.com', 'Sender Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Email with PDF attachment';
$mail->Body = 'Please see the attached PDF file.';

// Attach the PDF file
$pdfFilePath = 'path/to/your/file.pdf';
$mail->addAttachment($pdfFilePath);

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