Description:
------------
---
From manual page: http://www.php.net/function.array-values
---
array(0=>array(123)) == array(0=>array(0=>"123"))
//true

array_values(array(0=>array(123)))
// array(0=>array(0=>123))

array_values(array(0=>array(1=>123)))
// array(0=>array(0=>123))

array_values(array(0=>array(0=>123))) == array_values(array(0=>array(1=>123)))
// false

I don't know why, array_values returns completely same values but no equals to each other.

Test script:
---------------
<?php
assert('array(0=>array(123)) == array(0=>array(0=>"123"))');
assert('array_values(array(0=>array(0=>123))) == array_values(array(0=>array(1=>123)))');


Expected result:
----------------
true

Actual result:
--------------
false
