Derived classes may implement more than one interface. Interface support multiple inheritance | Abstract class does not support multiple inheritance It means you can extend an interfacewith one or more (hence multiple inheritance) interfaces like: interface Interface_A { } interface Interface_B { } use Pavan; After that, we created a class Sample. Note: To implement multiple interfaces, separate them with a comma (see example below). Just see the programming example. } In the below-listed PHP program’s example, there are two interfaces with the names “B1” and “C1” which are actually playing the role of the base classes and there is always a child class with the name “Multiple1” and we are now invoking all the other functions by using the “pavan” object. In PHP a class can only extend oneother class though, not multiple (sadly). Interface does'n contains Constructors | Abstract class contains Constructors It sounds like this point applies to may be other languages but in PHP an interface CAN have an empty constructor shell: interface MyInterface { public function __construct(); } Like other languages, PHP shouldn't have allowed having a constructor inside an interface. However, it can be achieved with interfaces, because the class can implement multiple interfaces. We all write and implement interfaces often, and we even implement multiple interfaces in classes many times. public function sayforp() { Here is our interface PaintCost in class Shape − public interface PaintCost { int getCost(int area); } The shape is our base class whereas Rectangle is the derived class − } If I bring up one in GUI, the other one goes down. & ans.

The problem is that only one of them can be active (i.e. In PHP, the interface blocks which declares set of functions to be defined with a class to implement this interface. } To implement multiple inheritances, use Interfaces. { The use of abstraction vs interfaces is problem specific and the choice is made during the design of software, not its implementation. The extends keyword is used once, and the parent interfaces are declared in a comma-separated list. Multiple inheritance using the interfaces is not about inheriting methods and variables. $check = new Sample1(); class Sample { Inheritance with Interface provides same job of multiple inheritance. Multiple inheritances works by inheriting the properties of the multiple super classes or parent classes to a subclass or the child class etc. Now you are in the interface C1"; At last, we created an object $obj of Sample class and called functions that will print the appropriate message on the webpage. » LinkedIn UNfortuantely my situation is that I have an M-audio interface, and have just purchased a roland TR8 which gives another 11 outputs.
