Overriding

Overriding is the process of updating an existing implementation (an inherited implementation) with a new one; it can be redeclaring a class attribute in derived objects or it can be taking an inherited member method to update with a whole new function body. Overriding keeps the external interface the same while the internal

functionalities might be fully changed to suit your own objectives. In PHP, you can do both attribute and method overriding. Note that this overriding happens in new classes derived by inheritance.
