How can the speed of sending newsletters be optimized in PHP?

To optimize the speed of sending newsletters in PHP, you can use batch processing to send emails in chunks rather than all at once. This can help prevent timeouts and improve performance by spreading out the sending process over multiple iterations. 

// Example code for sending newsletters in batches
$recipients = array('email1@example.com', 'email2@example.com', 'email3@example.com'); // List of recipients
$batchSize = 50; // Number of emails to send in each batch

for ($i = 0; $i < count($recipients); $i += $batchSize) {
    $batchRecipients = array_slice($recipients, $i, $batchSize); // Get a batch of recipients
    foreach ($batchRecipients as $recipient) {
        // Send newsletter to each recipient in the batch
        mail($recipient, 'Newsletter Subject', 'Newsletter Content');
    }
}
