Simple Abstract Class Example

Here, we will create an abstract class that contains abstract methods and then inherited the abstract class into a non-abstracted class and definition abstract methods.

PHP code to implement simple abstract class

The source code to demonstrate the example of a simple abstract class is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

<?php
//PHP program to demonstrate the example of the 
//simple abstract class.
abstract class AbsClass
{
    public abstract function fun1();
    public abstract function fun2();
}

class Sample extends AbsClass
{
    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 AbsClass which contains two abstract functions fun1() and fun2().

After that we created a class Sample, here we used the extends keyword to inherit an abstract class into the non-abstract class, then we defined the functions fun1() and fun2() into the Sample class.

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