PHP Bug Type: Scripting Engine problem
Bug description: key() malfunctions on references
Description:
------------
Consider the code below:
it does not produce correct results on 4.4, 5.1 head, but worked in some
5.0 versions due to the fact that key() is defined as by-ref function in
5.0.
Reproduce code:
---------------
<?
$state = array("one" => 1, "two" => 2, "three" => 3);
function foo( &$state ) {
$contentDict = end( $state );
for ( $contentDict = end( $state ); $contentDict !== false;
$contentDict = prev( $state ) ) {
echo key($state)."\n";
}
}
foo($state);
?>
Expected result:
----------------
three two one
Actual result:
--------------
one one one
