<?php
function test($numbers, $len)
    { 
         $arra_size = sizeof($numbers);

            for ($i = 0; $i < $len; $i++)
            {
                if ($numbers[$i] != $numbers[$arra_size - $len + $i])
                {
                    return false;
                }
            }

            return true;

var_dump(test([3, 7, 5, 5, 3, 7], 2));
var_dump(test([3, 7, 5, 5, 3, 7], 3));
var_dump(test([3, 7, 5, 5, 3, 7, 5], 3));
