Description:
------------
is simple, the code below works in version < 5.5, but version >= 5.5 does not work.

$arr = array("controller" => "IDoc\Home\ecommerce","request_method" => "POST");
$x = $arr["controller"];
$y = explode("\\",$x);
print_r($y);


the result correct is...

Array
(
    [0] => IDoc
    [1] => Home
    [2] => ecommerce
)

but in php >= 5.5 is wrong...

Array
(
    [0] => IDoc 
    [1] => Homecommerce
) 

Test script:
---------------
$arr = array("controller" => "IDoc\Home\ecommerce","request_method" => "POST");
$x = $arr["controller"];
$y = explode("\\",$x);
print_r($y);

Expected result:
----------------
Array
(
    [0] => IDoc
    [1] => Home
    [2] => ecommerce
)

Actual result:
--------------
Array
(
    [0] => IDoc 
    [1] => Homecommerce
)
