Description:
------------
using PHP Version 5.3.3, Build Date Jun 25 2012 04:51:11

In testing updating nested arrays, I'm finding the that the results of an array 
is not updated, since the variable used to point to that portion of the array 
seems to be a copy of the data and not a direct reference to the data.

Below is an array of arrays.

In the for loop, $sub points to $aryJunk's elements .. 0 .. 4 respectively.

When $sub has a new key value pair added, ex. "munch" => "junk", this value only 
exists as long as $sub exists in the for loop. Outside that loop, the key value 
pair are lost.

It is my understanding that this key value pair should not be lost.  Or, at 
least I cannot find an example that says definitively one way or the other.

Please test to see if this issue still exists in the latest version of PHP, and 
determine the next steps to resolution.

Test script:
---------------
$aryJunk = Array 
(
0 => array(),
1 => array(),
2 => array(),
3 => array(),
4 => array(),
);

// fails

foreach ($aryJunk AS $sub)
	$sub ["munch"] = "junk";

print_r ($aryJunk);

// works

for ($t=0; $t < count ($aryJunk); $t++)
	$aryJunk[$t] ["munch"] = "junk";
	
print_r ($aryJunk);


Expected result:
----------------
Array ( [0] => Array ( [munch] => junk ) [1] => Array ( [munch] => junk ) [2] => 
Array ( [munch] => junk ) [3] => Array ( [munch] => junk ) [4] => Array ( [munch] 
=> junk ) )

Actual result:
--------------
Array ( [0] => Array ( ) [1] => Array ( ) [2] => Array ( ) [3] => Array ( ) [4] => 
Array ( ) )
