PHP Exercises: Multiplies corresponding elements of two given lists

PHP: Exercise-43 with Solution

Write a PHP program that multiplies corresponding elements of two given lists.

Sample Solution:

PHP Code:

// Define a function to multiply two lists of numbers
function multiply_two_lists($x, $y)
    // Explode the input strings into arrays using spaces as delimiters
    $a = explode(' ', trim($x));
    $b = explode(' ', trim($y));

    // Initialize an empty array to store the multiplied values
    $output = array();

    // Iterate through each element of the arrays and multiply corresponding elements
    foreach ($a as $key => $value) {
        $output[$key] = $a[$key] * $b[$key];

    // Return the result by imploding the array into a string
    return implode(' ', $output);

// Test the function with example lists
echo multiply_two_lists(("10 12 3"), ("1 3 3"))."\n";


Sample Output:

10 36 9
