How can server-side processes related to PHP scripts, such as mail queues, be managed effectively to prevent issues like continuous email sending?

To prevent issues like continuous email sending in PHP scripts, server-side processes like mail queues can be managed effectively by implementing a delay mechanism between each email sending process. This delay helps to ensure that emails are sent at a controlled pace, preventing overwhelming the server and recipients with a large volume of emails.

// Set the delay time between each email sending process
$delay = 5; // Delay in seconds

// Loop through the email addresses in the queue
foreach ($emailQueue as $email) {
    // Send email
    mail($email['to'], $email['subject'], $email['message']);

    // Delay before sending the next email
    sleep($delay);
}
