How can one effectively encode and embed PDF attachments in emails using PHP?

To effectively encode and embed PDF attachments in emails using PHP, you can use the PHPMailer library which provides easy methods for adding attachments to emails. You will need to read the PDF file, encode it using base64 encoding, and then add it as an attachment to the email. 

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

require 'vendor/autoload.php';

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

// Set up the email parameters
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your@example.com';
$mail->Password = 'yourpassword';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

// Add attachments
$pdf_file = 'path/to/your/pdf/file.pdf';
$attachment_encoded = base64_encode(file_get_contents($pdf_file));
$mail->addStringAttachment($attachment_encoded, 'attachment.pdf', 'base64', 'application/pdf');

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

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