Description:
------------
I didn't find information on this bug online and couldn't update my version.
I have php 5.2.6 (installed with wampserver).

The bug is easy to reproduce so I thought I should just let you know as it may be related to other bugs that interpret the key value instead of reading it as a string in a 2D-array.

$params[] = array ("join" => "a", "join" => "b"); echo($params[0]);echo($params[0]);
returns "b" instead of "a"  
It seems as though when the key="join", previous entries of the array are deleted. 



Test script:
---------------
$params[] = array ("join" => "a", "join" => "b");
echo($params[0]);


Expected result:
----------------
I should be getting "a" 


Actual result:
--------------
I get "b"
