What are the potential pitfalls of using FPDF to generate PDF files for email attachments?

One potential pitfall of using FPDF to generate PDF files for email attachments is that the generated PDFs may not be compatible with all PDF viewers, leading to formatting issues or unreadable content for the recipient. To solve this issue, you can use a more robust PDF generation library like TCPDF, which offers better support for modern PDF features and compatibility with various PDF viewers. 

// Example of using TCPDF to generate a PDF file for email attachment
require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF();
$pdf->AddPage();
$pdf->SetFont('Helvetica', '', 12);
$pdf->Write(0, 'Hello, World!');
$pdf->Output('example.pdf', 'F');

// Attach the generated PDF file to an email
$attachment = chunk_split(base64_encode(file_get_contents('example.pdf')));
$filename = 'example.pdf';
$content = "Content-Type: application/octet-stream; name=\"$filename\"\n";
$content .= "Content-Transfer-Encoding: base64\n";
$content .= "Content-Disposition: attachment; filename=\"$filename\"\n\n";
$content .= $attachment;

// Send email with attachment
$to = 'recipient@example.com';
$subject = 'PDF Attachment';
$body = 'Please find the attached PDF file.';
$headers = "From: sender@example.com\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: multipart/mixed; boundary=\"boundary\"\r\n";
$headers .= "--boundary\n";
$headers .= "$content\n";
$headers .= "--boundary--";

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