Bug #35019 key() on array inside for loop returning wrong entry
Submitted: 2005-10-30 00:18 UTC Modified: 2005-10-30 19:04 UTC
From: pee at erkkila dot org Assigned: iliaa
Status: Closed Package: Arrays related
PHP Version: 5.1.0RC4 OS: linux

Description:
------------
Found a difference in mediawiki 1.5 with php4 vs php5. After tracking it down it looks like key() might be returning incorrect information inside a for loop. I might be missing a scope change someplace too though. This test case is based on Parser.php from that package.

Reproduce code:
---------------
<?php
function one(&$state) {
    $state = array (
        'oneKey' => "oneValue",
        'twoKey' => "twoValue",
        'threeKey' => "threeValue",
        'fourKey' => "fourValue",
    );
}

function two(&$state) {
    for ( $contentDict = end( $state ); $contentDict !== false; $contentDict = prev( $state ) ) {
        print("Key:" . key($state) . "\n");
        print("Value:" . $contentDict . "\n");
    }
}
one($state);
two($state);
?>


Expected result:
----------------
Key:fourKey
Value:fourValue
Key:threeKey
Value:threeValue
Key:twoKey
Value:twoValue
Key:oneKey
Value:oneValue


Actual result:
--------------
Key:oneKey
Value:fourValue
Key:oneKey
Value:threeValue
Key:oneKey
Value:twoValue
Key:oneKey
Value:oneValue
