Write a PHP program to check if a given array of integers contains 5 next to a 5 somewhere

<?php
function test($nums)
 { 

      for ($i = 0; $i < sizeof($nums) - 1; $i++)
          {
             if ($nums[$i] == 5 && $nums[$i] == $nums[$i + 1]) return true;
           }

            return false;
 }   

var_dump(test([1, 5, 6, 9, 10, 17]));
var_dump(test([1, 5, 5, 9, 10, 17]));
var_dump(test([1, 5, 5, 9, 10, 17, 5, 5]));
