ID: 46858 Updated by: jani@php.net -Summary: Incorrect isset result on MySQLi_Result properties Reported By: eric at livejournal dot dk -Status: Open +Status: Assigned Bug Type: MySQLi related -Operating System: Linux +Operating System: * -PHP Version: 5.2.8 +PHP Version: 5.2.9 -Assigned To: +Assigned To: andrey New Comment: Andrey, any possibility to fix this also in PHP_5_2 ? (See bug #44352) Previous Comments: ------------------------------------------------------------------------ [2008-12-31 16:11:47] eric at livejournal dot dk The property doesn't exist if the query failed. I realise I could simply check the error member, but I figured I'd still report it because IMO a bug exists - isset incorrectly returns false. ------------------------------------------------------------------------ [2008-12-18 15:28:28] jani@php.net Why do you test if that property exists anyway? It's always there, you don't need to test for that. :) ------------------------------------------------------------------------ [2008-12-13 16:46:02] eric at livejournal dot dk Description: ------------ isset returns false when applied to a MySQLi_result object that does indeed exist. Reproduce code: --------------- <?php $db = new mysqli('localhost', 'test', 'test', 'test'); $result = $db->query('SELECT * FROM test;'); //contains 1 row echo $result->num_rows; if (isset($result->num_rows)) echo 'defined'; else echo 'undefined'; ?> Expected result: ---------------- 1defined Actual result: -------------- 1undefined ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46858&edit=1
