Write a PHP program to create a new array from a given array of integers shifting all zeros to left direction

<?php
function test($numbers)
    { 
       $pos = 0;
       for ($i = 0; $i < sizeof($numbers); $i++)
            {
                if ($numbers[$i] == 0)
                {
                    $numbers[$i] = $numbers[$pos];
                    $numbers[$pos++] = 0;
                }
            }
            return $numbers;
    }  
    
$result = test([1, 2, 0, 3, 5, 7, 0, 9, 11] );
echo "New array: " . implode(',', $result);
