Interface Dependency in PHP

Interface Dependency

An interface can also extend another interface which allow us to define dependencies.

              
                interface A {
                  public function do1();
                  public function do2();
                }

                interface B extends A { // you could extends function from another interface
                  public function do1();
                  public function do3();
                }

                class C implements B {

                  public function do1() {
                    // you could define your custom behavior here
                  }

                  public function do2() {
                    // you could define your custom behavior here
                  }

                  public function do3() {
                    // you could define your custom behavior here
                  }
                }
