Is there a recommended method for handling a large number of email addresses in a PHP script for mass mailing?

When handling a large number of email addresses in a PHP script for mass mailing, it is recommended to use a batch processing approach to prevent memory issues and optimize performance. This involves breaking down the list of email addresses into smaller batches and sending emails to each batch separately. 

// List of email addresses
$emailAddresses = array('email1@example.com', 'email2@example.com', 'email3@example.com', ...);

// Batch size
$batchSize = 100;

// Split email addresses into batches
$emailBatches = array_chunk($emailAddresses, $batchSize);

// Loop through each batch and send emails
foreach ($emailBatches as $batch) {
    foreach ($batch as $email) {
        // Send email to $email
        // Your email sending code here
    }
}
