PHP Exercises: Capture a variable number of arguments to a given function

PHP: Exercise-102 with Solution

Write a PHP program to capture a variable number of arguments to a given function.

Sample Solution:

PHP Code:

<?php
// Licence: https://bit.ly/2CFA5XY

// Function definition for 'variadicFunction' that takes an array of operands as a parameter
function variadicFunction($operands)
{
    // Initialize a variable to store the sum of operands
    $sum = 0;

    // Iterate through each operand in the array and add it to the sum
    foreach($operands as $singleOperand) {
        $sum += $singleOperand;
    }

    // Return the final sum
    return $sum;
}

// Call 'variadicFunction' with an array containing two operands and display the result using 'var_dump'
var_dump(variadicFunction([1, 2]));

// Call 'variadicFunction' with an array containing four operands and display the result using 'var_dump'
var_dump(variadicFunction([1, 2, 3, 4]));
  
?>

Sample Output:

int(3)
int(10)
