JSON Array to Double Array PHP Bug(?)

Attempt to demonstrate a potential PHP Bug wherein a string of data that includes an equals sign (=), when json_encode()'d twice and delivered to a web server, will be interpreted as a split in a data array.

Building the request

Child Data:
array (size=2)
  'one' => string 'one is one' (length=10)
  'two' => string 'two = two' (length=9)
The Child Data array is json_encode()'d and appended to the Parent Data.
Parent Data:
array (size=1)
  'requests' => string '{"one":"one is one","two":"two = two"}' (length=38)
The Parent Data is again json_encode()'d and and will be sent to the server.
string '{"requests":"{\"one\":\"one is one\",\"two\":\"two = two\"}"}' (length=61)
Sending to service ...
Server Results:

array (size=1)
  '{"requests":"{\"one\":\"one_is_one\",\"two\":\"two_' => string ' two\"}"}' (length=9)
