error_reporting(-1);
$arr = NULL;
var_dump($arr[0]);

==> NULL !!! no warnings at all!

Tested with:
PHP 5.3.10
PHP 5.5.9

Description:
------------
If you define variable as NULL and then you want to acces it over keys as array 
like $array['kolo'] then PHP should trigger a strict error and not return the NULL.

Test script:
---------------
<?php

$array = null;
var_dump($array['kolo']);

/* 
Expected result:
PHP strict error

Actual result:
NULL
*/


Expected result:
----------------
Expected is PHP strict error.

Actual result:
--------------
NULL
