Description:
------------
Hi,

Note : PHP Version 5.2.17, but I can't update the version of php, it is installed on a shared server.

Loop to change the values in an array by reference and then another loop but same variable name, the initial array is modified again.

Test script:
---------------
<?php
	$arrayOne = array(
		'key1' => array('k1' => 'val_key1_k1'),
		'key2' => array('k1' => 'val_key2_k1')
	);
	
	foreach ($arrayOne as $localKey => &$localValue)	// character & 
		$localValue['k1'] .= '_add';
	
	// -----
	
	print_r($arrayOne);
	
	$counter = 0;
	foreach ($arrayOne as $k => $localValue)		// same name of variable "$localValue", but local
		$counter++;
	
	print_r($arrayOne);					// is the same array ? => NO !
?>

Expected result:
----------------
		Array
		(
		    [key1] => Array
		        (
		            [k1] => val_key1_k1_add
		        )
		
		    [key2] => Array
		        (
		            [k1] => val_key2_k1_add
		        )
		
		)



Actual result:
--------------
		Array
		(
		    [key1] => Array
		        (
		            [k1] => val_key1_k1_add
		        )
		
		    [key2] => Array
		        (
		            [k1] => val_key1_k1_add	// Hey! My value changed here !
		        )
		
		)
