Description:
------------
There's several reasons to want an easily parsed phpinfo() output, chief amongst them to ensure that a series of servers have the same packages, and are configured in the same manner. There's a series of solutions[1] built on top of using the output from phpinfo(), then parsing it back into arrays. Clearly this is sub-optimal.

A userland alternative would be to run through the various functions like ini_get(), get_loaded_extensions(), etc. But not quite as pretty, I'm not sure if the same level of information is even exposed there (phpinfo() shows me master, and current, can I get that from ini_get())?



[1] like http://php.net/phpinfo#84259

Test script:
---------------
$config = phpinfo(-1, TRUE);
echo json_encode($config);


Expected result:
----------------
A beautiful json output of the PHP's server configuration. I'd then be able to use PHP's glorious array functions to easily compare it to another server's and find problems. 

Actual result:
--------------
Hrm, this seems like the kind of question I'd see on a test. phpinfo() will error because it's not expecting the second parameter, so I'll run with C) error.
