Write a PHP program to check a given array of integers and return true if the given array contains two 5's next to each other, or two 5 separated by one element

<?php
function test($numbers)
 { 
      $len = sizeof($numbers);
      for ($i = 0; $i < $len - 1; $i++)
         {
           if ($numbers[$i] ==5 && $numbers[$i + 1] == 5) return true;
           if ($i + 2 < $len && $numbers[$i] == 5 && $numbers[$i + 2] == 5) return true;
         }

            return false;
 }   

var_dump(test([5, 5, 1, 5, 5]));
var_dump(test([1, 2, 3, 4]));
var_dump(test([3, 3, 5, 5, 5, 5]));
var_dump(test([1, 5, 5, 7, 8, 10]));
