How can PHP developers optimize their code to improve the performance of sending mass notifications or newsletters?

To optimize the performance of sending mass notifications or newsletters in PHP, developers can batch process the sending of emails instead of sending them all at once. This can help reduce server load and prevent timeouts. Additionally, using a queue system like RabbitMQ or Redis can help manage the sending process more efficiently. 

// Example of sending emails in batches using PHP
$recipients = ['email1@example.com', 'email2@example.com', 'email3@example.com'];
$batchSize = 50; // Number of emails to send in each batch

// Split recipients into batches
$batches = array_chunk($recipients, $batchSize);

// Loop through batches and send emails
foreach ($batches as $batch) {
    foreach ($batch as $recipient) {
        // Code to send email to $recipient
        echo "Sending email to $recipient...\n";
    }
    
    // Delay between batches to prevent server overload
    sleep(1);
}
