Description:
------------
In 5.2.14, json_encode() silently discards any array values for which the array 
key is an empty string. This seems identical to Bug #41505, but affects PHP 
5.2.14.

Demonstration code:
var_dump(json_encode(array("" => array("a" => 1))));

Expect (result in 5.2.6, 5.2.10, 5.2.13, 5.3.2):
string(12) "{"":{"a":1}}"

Receive (in 5.2.14):
string(2) "{}"

Test script:
---------------
var_dump(json_encode(array("" => array("a" => 1))));

Expected result:
----------------
string(12) "{"":{"a":1}}"

Actual result:
--------------
string(2) "{}"

I can't reproduce this in PHP 5.2.14:

root@router:~# php -v
PHP 5.2.14 (cli) (built: Aug 18 2010 17:16:15)
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2010 Zend Technologies
root@router:~# php
<?php
dl("json.so");
var_dump(json_encode(array("" => array("a" => 1))));
string(12) "{"":{"a":1}}"

But even if there was actually a bug, PHP 5.2 is only to receive security updates at this point. So Bogus/Wont Fix.
