PHP program to demonstrate the single inheritance

Program/Source Code:

The source code to demonstrate the single inheritance is given below. The given program is compiled and executed successfully.

<?php
//PHP program to demonstrate the single inheritance.
class Base
{
    function BaseFun()
    {
        echo "BaseFun() called<br>";
    }
}

class Derived extends Base
{
    function DerivedFun()
    {
        echo "DerivedFun() called<br>";
    }
}

$dObj = new Derived();

$dObj->BaseFun();
$dObj->DerivedFun();

?>

Output:

BaseFun() called
DerivedFun() called

Explanation:

In the above program, we created two classes Base and Derived. Here, we inherited the Base class into the derived class using the extends keyword.

The Base class contains a function BaseFun(), and Derived class also contains only one function DerivedFun().

At last, we created the object $dObj of the derived class. Then called BaseFun() and DerivedFun() using the object that will print the appropriate message on the webpage.
