I have been working on a PHP project lately and I came across the Observer design pattern. I was wondering if it is possible to implement this pattern in PHP.
I have heard that the Observer pattern is great for handling events and notifications in a loosely coupled manner. It allows objects to subscribe and unsubscribe from certain events, and the subscribing objects will be notified whenever an event occurs.
I was thinking of using the Observer pattern in my project to handle certain notifications and updates. However, since PHP is a scripting language, I'm not sure if it supports implementing such a pattern.
Has anyone tried implementing the Observer design pattern in PHP before? If so, could you please share your experience and insights on how to go about it? Any code examples or tutorials would be highly appreciated.
Thank you in advance for your help!
