How can PHP be optimized to efficiently process and send multiple emails based on form submissions?

To efficiently process and send multiple emails based on form submissions in PHP, you can optimize the code by using a loop to iterate through the list of recipients and send individual emails to each one. This approach avoids sending bulk emails in a single request, which can lead to performance issues and potential email delivery problems. 

// Sample code snippet to send multiple emails efficiently
$recipients = ['email1@example.com', 'email2@example.com', 'email3@example.com'];

foreach ($recipients as $recipient) {
    $to = $recipient;
    $subject = 'Your Subject Here';
    $message = 'Your Email Message Here';
    $headers = 'From: yourname@example.com' . "\r\n" .
        'Reply-To: yourname@example.com' . "\r\n" .
        'X-Mailer: PHP/' . phpversion();

    // Send email
    mail($to, $subject, $message, $headers);
}
