What is the recommended method for sending emails to multiple users with attachments using PHP?

When sending emails to multiple users with attachments using PHP, it is recommended to use a loop to iterate through the list of recipients and attach the files before sending the email. This ensures that each recipient receives the email with the appropriate attachment. 

<?php

// List of recipients
$recipients = array('recipient1@example.com', 'recipient2@example.com');

// Email subject
$subject = 'Email with attachments';

// Email message
$message = 'Please see the attached files.';

// File paths
$attachments = array('file1.pdf', 'file2.jpg');

// Send email to each recipient with attachments
foreach($recipients as $recipient) {
    $headers = 'From: sender@example.com' . "\r\n";
    
    $mail = new PHPMailer();
    $mail->isSMTP();
    $mail->Host = 'smtp.example.com';
    $mail->SMTPAuth = true;
    $mail->Username = 'your_smtp_username';
    $mail->Password = 'your_smtp_password';
    $mail->SMTPSecure = 'ssl';
    $mail->Port = 465;

    $mail->setFrom('sender@example.com', 'Sender Name');
    $mail->addAddress($recipient);
    $mail->Subject = $subject;
    $mail->Body = $message;
    
    foreach($attachments as $attachment) {
        $mail->addAttachment($attachment);
    }
    
    if(!$mail->send()) {
        echo 'Message could not be sent.';
        echo 'Mailer Error: ' . $mail->ErrorInfo;
    } else {
        echo 'Message has been sent';
    }
}
?>
