dpacmittal Posted November 29, 2009 Share Posted November 29, 2009 I am learning OOP in PHP and its been a pretty good learning experience so far. What I didn't understand at all is interfaces. I understand the implications of multiple inheritance, and interface is used just to solve that. But what's the use? If we have to define the function in derived class why use interface, why not directly declare and define it inside the derived class? Am I missing something or is it really useless?

Alex Posted November 29, 2009 Share Posted November 29, 2009 As with many standards in programming (especially with OOP) interfaces aren't totally for you, they're for other programmers that might use your code. It's a good way to insure that an object will maintain certain methods. Quote Link to comment Share on other sites More sharing options...

Alex Posted November 29, 2009 Share Posted November 29, 2009 Definitely not one of the most useful features in PHP, but it can come in handy sometimes, especially when you plan on distributing your code. Quote Link to comment Share on other sites More sharing options...
