class Newsletter { private $subscribers = []; public function addSubscriber($email) { $this->subscribers[] = $email; } } $newsletter = new Newsletter(); $newsletter->addSubscriber('john@example.com'); $newsletter->addSubscriber('jane@example.com');
$subscriber_email = 'bob@example.com'; $newsletter_id = 123; $response = self::addSubscriber($subscriber_email, $newsletter_id); if ($response['success'] === true) { echo 'Successfully subscribed!'; } else { echo 'Sorry, something went wrong.'; }In this example, self addSubscriber is a static method that takes an email address and a newsletter ID as arguments, and returns an associative array with a 'success' key that indicates whether the subscription was successful or not. You can call this method to subscribe a user to a newsletter, and then check the response to see if it was successful. Package library: Unknown
