How Can I Attach PDFs to Emails Using PHP's `mail()` Function?

Attaching Files with PHP Mail()

Sending emails with PDF attachments using PHP's mail() function can be a daunting task, but it is possible. The built-in mail() function lacks support for attaching files, which makes the process more complicated.

Solution: Use a Third-Party Script

To overcome this limitation, consider using a third-party script like PHPMailer. PHPMailer provides a comprehensive solution for sending emails, including those with attachments. Using PHPMailer simplifies the process significantly compared to manually handling the attachment complexities with mail().

Step-by-Step Guide to Use PHPMailer

To attach files using PHPMailer, follow these steps:

1. Download and Extract PHPMailer: Visit the official GitHub page to download the PHPMailer script.
2. Include the Main Script File: Include the 'class.phpmailer.php' file in your code.
3. Create a PHPMailer Object: Instantiate a new PHPMailer object.
4. Set Sender, Subject, and Body: Configure the sender's email, subject, and message body.
5. Add Attachment: Use the 'AddAttachment' method to attach the desired PDF file.
6. Send Email: Invoke the 'Send' method to send the email with the attachment.

Example Code:

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

$email = new PHPMailer();
$email->setFrom('[email protected]', 'Your Name');
$email->Subject = 'Message Subject';
$email->Body = $bodytext;
$email->addAddress('[email protected]');
$email->addAttachment('PATH_OF_YOUR_FILE_HERE', 'NameOfFile.pdf');

$email->send();
