Program/Source Code:

The source code to demonstrate the method overloading based on the number of arguments is given below. The given program is compiled and executed successfully.

<?php
//PHP program to demonstrate the method overloading
//based on the number of arguments.
class Sample
{
    function __call($function_name, $args)
    {

        if ($function_name == 'sum')
        {
            switch (count($args))
            {
                case 2:
                    return $args[0] + $args[1];
                case 3:
                    return $args[0] + $args[1] + $args[2];
            }
        }
    }
}

$obj = new Sample();

printf("Sum: " . $obj->sum(10, 20) . "<br>");
printf("Sum: " . $obj->sum(10, 20, 30) . "<br>");
?>

Output:

Sum: 30
Sum: 60

Explanation:

Here, we created a class Sample and then implemented magic function __call() to perform method overloading to add numbers based on the number of arguments. Here, we used switch cases for the number of arguments and return the sum of numbers.

At last, we created the object $obj of the Sample class and the call sum method with a different number of arguments and print the result on the webpage.
