How can the PHP "mail" function be utilized effectively to handle form submissions and send notifications to multiple recipients?

To handle form submissions and send notifications to multiple recipients using the PHP "mail" function, you can utilize the "Bcc" header to send the email to multiple recipients without revealing their email addresses to each other. This ensures privacy and simplifies the process of sending notifications to multiple recipients.

<?php
$to = "recipient1@example.com, recipient2@example.com";
$subject = "Form Submission Notification";
$message = "This is a notification email for the form submission.";
$headers = "From: sender@example.com\r\n";
$headers .= "Bcc: recipient1@example.com, recipient2@example.com\r\n";

mail($to, $subject, $message, $headers);
?>
