How can PHP scripts be optimized to efficiently handle and process email attachments, especially when dealing with large volumes of data?

To efficiently handle and process email attachments in PHP, especially when dealing with large volumes of data, you can optimize your scripts by using libraries like PHPMailer or Swift Mailer. These libraries provide built-in functions for handling attachments, such as chunking large files to avoid memory issues and improving performance. Additionally, you can optimize your code by using proper error handling, implementing caching mechanisms, and optimizing database queries to reduce processing time. 

// Example using PHPMailer library for handling email attachments efficiently
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

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

// Add attachments
$mail->addAttachment('/path/to/file1.pdf');
$mail->addAttachment('/path/to/file2.pdf');

// Send the email
$mail->send();
