Question

I was just reading through a tutorial and they mentioned that Objects in php are just the better way of arrays. I am confused? Can someone clear the concept for me.
thanks

Answer 1

That was more or less true for PHP 4, where there was no actual encapsulation. In fact, objects provide some benefits over plain array:

• Encapsulation (private and protected members) – easier to preserve invariants.
• Inheritance – a type inherits the default behaviour of its superclass, you only have to replace the parts that differ.
• Dynamic dispatch (the method that’s actually called depends on the type of variable) – provides decoupling of interface and implementation and abstraction.
• Less polution of global namespace with functions (less compelling since the introduction of namespaces in PHP 5.3)
