Bug description:  Surprising array bug found with special word "lang"

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

I have found the following problem. I try to produce a query string and I
found that using lang as a key makes problem with implode.

Reproduce code:
---------------
<?php
$all = array(
	'turkce',
	'english',
	'german'
);

$t = array();
foreach ($all as $al) {
	$t[] = 'lang[]='.$al;
}

echo implode('&',$t);
?>

Expected result:
----------------
lang[]=turkce&lang[]=english&lang[]=german

Actual result:
--------------
lang[]=turkce&#9001;[]=english&#9001;[]=german
