Description:
------------
PHP 5.3 introduced a new configuration option named 'request_order'.

# Added "request_order" INI variable to control specifically _REQUEST behavior. (Stas)"
http://www.php.net/ChangeLog-5.php#5.3.0

It's default value within php.ini (and related comments) are:

--
; This directive determines which super global data (G,P,C,E & S) should
; be registered into the super global array REQUEST. If so, it also determines
; the order in which that data is registered. The values for this directive are
; specified in the same manner as the variables_order directive, EXCEPT one.
; Leaving this value empty will cause PHP to use the value set in the
; variables_order directive. It does not mean it will leave the super globals
; array REQUEST empty.
; Default Value: None
; Development Value: "GP"
; Production Value: "GP"
; http://www.php.net/manual/en/ini.core.php#ini.request-order
request_order = "GP"
--

This variable omits 'C' for COOKIES.

Versions prior to PHP 5.3 merged the contents of the _COOKIE array into _REQUEST.

Due to this default configuration change, _REQUEST can no longer be used to access cookie values without modifying the request_order php.ini variable.

This changes how _REQUEST is used in PHP 5.3 by default.

This appears to be an oversight/bug, because the PHP documentation still indicates that _REQUEST can be used to access cookies.

" An associative array that by default contains the contents of _GET, _POST and _COOKIE. "

Suggested Fix: Update PHP 5.3's default php.ini configuration file to have 'GPC' instead of 'GP' for 'request_order', to restore prior functionality.


Test script:

Expected result:
----------------
The line '_REQUEST has the cookie, no bug present.' because the default php.ini config value for request_order should be 'GPC' to include cookies.


Actual result:
--------------
The line '_REQUEST is missing TestCookie, there is a bug.' because the default php.ini config value for request_order currently omits cookies ('GP').
