Program/Source Code:

The source code to demonstrate the function returning object is given below. The given program is compiled and executed successfully.

<?php
//PHP programs to demonstrate the function returning object.
class Number
{
    public $Num;

    function __construct($n)
    {
        $this->Num = $n;
    }

    function Display()
    {
        echo "Num: " . $this->Num;
    }
}

function AddObj($obj1, $obj2)
{
    $temp = new Number(0);

    $temp->Num = $obj1->Num + $obj2->Num;

    return $temp;
}

$Obj1 = new Number(10);
$Obj2 = new Number(20);

$Obj3 = AddObj($Obj1, $Obj2);

$Obj3->Display();

?>

Output:

Num: 30

Explanation:

In the above program, we created a class Number that contains a data member $Num, parameterized constructor, and a Display() method.

The parameterized constructor is used to initialized the value of data members and the Display() method is used to display the value of data members on the webpage.

Here, we created a function AddObj() that accepts two object arguments and then adds the values of data members. Here we stored the result in a temporary object and return the temporary object.

At last, we created the two objects and passed the object into AddObj() function and then assigned the returned object to the $Obj3 after that called the Display() method that will print the value of data members on the webpage.
