Creating an array to object hydrator

The Hydrator pattern is a variation of the Data Transfer Object design pattern. Its design principle is quite simple: moving data from one place to another. In this illustration, we will define classes to move data from an array to an object.

   namespace Application\Generic\Hydrator;
   class GetSet
   {
     // code
   }

2. Next, we define a hydrate() method, which takes both an array and an object as arguments. It then calls the setXXX() methods on the object to populate it with values from the array. We use get_class() to determine the object's class, and then get_class_methods() ...
