How can PHP scripts be set up to automatically send notification emails when certain actions are taken?

To automatically send notification emails when certain actions are taken in PHP scripts, you can use the `mail()` function to send an email. You will need to set up the appropriate headers, such as the recipient email address, subject, and message content. Additionally, you can trigger the email sending function after the specific action is completed in your script.

// Set up email parameters
$to = "recipient@example.com";
$subject = "Notification Email";
$message = "This is a notification email for a certain action.";

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