phpmailerHow do I use PHPMailer to send an email to multiple addresses?

Using PHPMailer to send an email to multiple addresses is quite simple. The following example code shows how to do it:

<?php
// Import PHPMailer classes into the global namespace
// These must be at the top of your script, not inside a function
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

// Load Composer's autoloader
require 'vendor/autoload.php';

// Instantiation and passing `true` enables exceptions
$mail = new PHPMailer(true);

try {
    //Recipients
    $mail->setFrom('[email protected]', 'Mailer');
    $mail->addAddress('[email protected]', 'Recipient 1');
    $mail->addAddress('[email protected]', 'Recipient 2');
    $mail->addAddress('[email protected]', 'Recipient 3');
    $mail->addReplyTo('[email protected]', 'Reply To');

    // Content
    $mail->isHTML(true);
    $mail->Subject = 'Here is the subject';
    $mail->Body    = 'This is the HTML message body <b>in bold!</b>';
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {
    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}

The output of this code will be Message has been sent.

The code consists of the following parts:

1. Importing the PHPMailer classes into the global namespace.
2. Loading Composer's autoloader.
3. Instantiating PHPMailer and passing true to enable exceptions.
4. Setting the sender of the email.
5. Adding recipients to the email.
6. Setting the content of the email.
7. Sending the email.
8. Outputting a message if the email was sent successfully.
