Description:
------------
Looking at the online document reference for the HttpRequest class; the 
properties/fields indicate the wrong modifier. The stated modifier is "protected" 
when in fact it is "private".

The online documentation in question can be found here: 
http://www.php.net/manual/en/class.httprequest.php

Test script:
---------------
php --rc httprequest

-- output:
...
  - Properties [16] {
    Property [ <default> private $options ]
    Property [ <default> private $postFields ]
