Inheriting an Abstract Class and An Interface in a Non-Abstract Class

Here, we will create an abstract class and an interface then we inherited them into a non-abstract class.

Program

The source code to inherit an abstract class and an interface in a non-abstract class is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

<?php
//PHP program to inherit an abstract class 
//and an interface in a non-abstract class.
abstract class Abs
{
    public abstract function fun1();
}

interface Inf
{
    public function fun2();
}

class Sample extends Abs implements Inf
{
    public function fun1()
    {
        printf("fun1() called<br>");
    }
    public function fun2()
    {
        printf("fun2() called<br>");
    }
}

$obj = new Sample();

$obj->fun1();
$obj->fun2();

?>

Output

fun1() called
fun2() called

Explanation

In the above program, we created an abstract class Abs and an interface Inf and then we inherited the abstract class and interface into a non-abstract class Sample, and defined the functions.

At last, we created three objects $obj of Sample class and called functions that will print the appropriate message on the webpage.
