I used the magic methods __set() and __get() to facilitate error handling. These methods fire when a property is not accessible. So when the property does not exist these will fire. So first we init the properties when we create an instance (I'll discuss this shortly)... to init them we are setting them, this fires the __set() method... but since we check the value of the private ___init property, we don't fire an error in this instance. Future requests for the properties will not incurr a hit to __set() or __get() as long as the property is defined. If it is not defined then voila, the error fires and we die (we could do anything such as fire an exception but I just die for the example). With respect to initialization I use func_get_args() so that an arbitrary number of parameters can be passed to the constructor. This is useful since we don't know the number of properties. I also check if an argument is an array. If it is an array then I treat it as a property with an initialized value and create and set the property accordingly. That's all there is to it.
