What potential issues can arise when sending a PDF as an email attachment using PHP?

One potential issue that can arise when sending a PDF as an email attachment using PHP is that the PDF file may not be properly encoded for email transmission, leading to corruption or unreadable content. To solve this issue, you can use the PHPMailer library, which handles file attachments and encoding automatically. 

// Include the PHPMailer library
require 'path/to/PHPMailer/PHPMailerAutoload.php';

// Create a new PHPMailer instance
$mail = new PHPMailer;

// Set up the email parameters
$mail->setFrom('your@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Attachment Test';
$mail->Body = 'Please see the attached PDF file.';

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

// Send the email
if (!$mail->send()) {
    echo 'Email could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Email has been sent';
}
