note 102903 added to mysqli.query

When calling multiple stored procedures, you can run into the following error: "Commands out of sync; you can't run this command now". This can happen even when using the close() function on the result object between calls. To fix the problem, remember to call the next_result() function on the mysqli object after each stored procedure call. See example below: // New Connection $db = new mysqli('localhost','user','pass','database'); // Check for errors if(mysqli_connect_errno()){ echo mysqli_connect_error(); } // 1st Query $result = $db->query("call getUsers()"); if($result){ // Cycle through results while ($row = $result->fetch_object()){ $user_arr[] = $row; } // Free result set $result->close(); $db->next_result(); } // 2nd Query $result = $db->query("call getGroups()"); if($result){ // Cycle through results while ($row = $result->fetch_object()){ $group_arr[] = $row; } // Free result set $result->close(); $db->next_result(); } else echo($db->error); // Close connection $db->close(); ---- Server IP: 69.147.83.197 Probable Submitter: 41.177.93.195 ---- Manual Page -- http://www.php.net/manual/en/mysqli.query.php Edit -- https://master.php.net/note/edit/102903 Del: integrated -- https://master.php.net/note/delete/102903/integrated Del: useless -- https://master.php.net/note/delete/102903/useless Del: bad code -- https://master.php.net/note/delete/102903/bad+code Del: spam -- https://master.php.net/note/delete/102903/spam Del: non-english -- https://master.php.net/note/delete/102903/non-english Del: in docs -- https://master.php.net/note/delete/102903/in+docs Del: other reasons-- https://master.php.net/note/delete/102903 Reject -- https://master.php.net/note/reject/102903 Search -- https://master.php.net/manage/user-notes.php
