PHP Exercises: Create a new string which is n copies of a given string

PHP Basic Algorithm: Exercise-25 with Solution

Write a PHP program to create a new string which is n (non-negative integer) copies of a given string.

Sample Solution:

PHP Code :

<?php
// Define a function that repeats a string $n times
function test($s, $n) 
{
    // Initialize an empty string to store the result
    $result = "";

    // Iterate $n times and concatenate the input string to the result
    for ($i = 0; $i < $n; $i++) {
        $result = $result . $s;
    }

    // Return the final result
    return $result;
}

// Test the function with different inputs
echo test("JS", 2) . "\n";
echo test("JS", 3) . "\n";
echo test("JS", 1) . "\n";
?>

Sample Output:

JSJS
