This is really buggy.

$test['0']; // prints int(0)

but

$key = '0'; 
$test[$key]; // prints string(1) "0"

numeric string key will cast to number, I think this is a improvement, to be 
consistent with the internal dim fetch.

but yeah, we need a document of such change, change to doc problem.

Description:
------------
Execute the test script provided below in php 5.3.10 and php 5.4.0-3 may get different results which
are string(1) "0" and int(0).

I don't know if this is a bug or a patch.

Test script:
---------------
<?php
class Test implements ArrayAccess {

    public function offsetExists($off)
    {
    }

    public function offsetUnset($off)
    {
    }

    public function offsetSet($off, $el)
    {
    }

    public function offsetGet($off)
    {
        var_dump($off);
    }
}

$test = new Test();

$test['0'];

Expected result:
----------------
string(1) "0"

Actual result:
--------------
int(0)
