class Notifier { private $mailer; public function __construct() { $this->mailer = new Mailer(); } public function notify() { … $this->mailer->send($from, $to, $msg); … }}
class Notifier { private $mailer; public function __construct(MailInterface $m) { $this->mailer = $m; } public function notify() { …. $this->mailer->send($from, $to, $msg); … }}
$mailer = new SpecialMailer();$notifier = new Notifier($mailer);
