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 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=35019&edit=1
