What are common challenges when sending PDF attachments in PHP?

One common challenge when sending PDF attachments in PHP is ensuring that the file is properly encoded before sending it via email. To solve this, you can use the base64_encode function to encode the PDF file before attaching it to the email. 

// Path to the PDF file
$pdfFilePath = 'path/to/your/pdf/file.pdf';

// Read the PDF file content
$pdfContent = file_get_contents($pdfFilePath);

// Encode the PDF file content
$encodedPdf = base64_encode($pdfContent);

// Add the attachment to the email
$mail->addStringAttachment($encodedPdf, 'file.pdf', 'base64', 'application/pdf');
