How to add a method to an existing class in PHP?

Question

I\'m using WordPress as a CMS, and I want to extend one of its classes without having to inherit from another class; i.e. I simply want to \"add\" more methods to that class

Answer 1

No you can't dynamically change a class during runtime in PHP.

You can accomplish this by either extending the class using regular inheritance:

class Fancy extends NotSoFancy
{
    public function whatMakesItFancy() //can also be private/protected of course
    {
        //    
    }
}

Or you could edit the Wordpress source files.

I'd prefer the inheritance way. It's a lot easier to handle in the long run.
