Write a PHP program to create a new string which is n (non-negative integer) copies of the the first 3 characters of a given string

<?php
function test($s, $n)
{
    $result = "";
    $frontOfString = 3;

    if ($frontOfString > strlen($s))
        $frontOfString = strlen($s);

       $front = substr($s, 0, $frontOfString);

    for ($i = 0; $i < $n; $i++)
         {
            $result = $result.$front;
        }
     return $result;
 }


echo test("Python", 2)."\n";
echo test("Python", 3)."\n";
echo test("JS", 3)."\n";
