Bug description: key() function changed behaviour if global array is used
within function
Description:
------------
If a global array is assigned to a local variable as in the example, and
the local variable is iterated afterwards, the key() function changed the
behaviour in the global scope with PHP 5.2.1.
Reproduce code:
---------------
<?php
function foo()
{
global $arr;
$c = $arr["v"];
foreach ($c as $v) {}
}
$arr["v"] = array("a");
echo "-".key($arr["v"])."-"; // prints "0"
foo();
echo "<br/>-".key($arr["v"])."-"; // prints "" since 5.2.1 ("0" on all
prior versions)
?>
Expected result:
----------------
-0-
-0-
Actual result:
--------------
-0-
