phpoopclassextend

Is it possible to extend a class dynamically?

I have a class which I need to use to extend different classes (up to hundreds) depending on criteria. Is there a way in PHP to extend a class by a dynamic class name?

I assume it would require a method to specify extension with instantiation.

Ideas?

  • I don't think it's possible to dynamically extend a class (however if I'm wrong I'd love to see how it's done). Have you thought about using the Composite pattern (http://en.wikipedia.org/wiki/Composite_pattern, http://devzone.zend.com/article/7)? You could dynamically composite another class (even multiple classes - this is often used as a work around to multiple inheritance) to 'inject' the methods/properties of your parent class into the child class.
