Tutorial on PHP class, interface, overload method, introspection class functions class iterator.Class variable name substitution. s "v1" test->s Same as test->v1. Initialize PHP instance variable. Polymorphism: The name suggests one name and multiple functions. Using this OOPs concept we can use the same function to serve multiple purposes.Following is the demonstration of Anonymous class in PHP 7, a newly added feature. Explanation. Firstly, we have defined an interface Data that / Remember: when a class uses/implements an interface, the class MUST define all the methods/functions of the interface otherwise the php engine will barf barf is a technical term for: give you an error.
