ID: 45289 Comment by: me at lucasoman dot com Reported By: mike dot benza at rice dot edu Status: Open Bug Type: MySQLi related Operating System: All PHP Version: 5.2.6 New Comment:
I've experienced the same on 5.1.6. The only difference is that the returned associative array values were all null, as far as I could tell (I didn't get any garbage, as above). The keys were all correct. Also, the correct number of result rows were returned. Previous Comments: ------------------------------------------------------------------------ [2008-06-17 02:33:54] mike dot benza at rice dot edu Description: ------------ It's not possible (as far as I can tell) to use a prepared statement in conjunction with mysqli_result::fetch_row or mysqli_result::fetch_assoc. The inability to do it is not documented in the manual online. There is no error given when you try to use fetch_row or fetch_assoc on a result. In fact, it returns successfully, with garbage. This is a similar issue as http://bugs.php.net/bug.php?id=42619&edit=2, but there is still no documentation of the behavior and no error thrown when trying to use fetch_row or fetch_assoc on a result from a prepared statement (Note: I only have 5.2.4, since that's the highest available on my OS. If you really want me to upgrade, I'll build it from source, but I think you know about this incompatibility, since it should be your primary use case; mysqli should be able to combine the security of prepared statements with the useful features of the old mysql extension) (See also: http://www.robpoyntz.com/blog/?p=189, which doesn't work, and I haven't had a chance to figure out why) (See also: http://blog.myhat.de/2007/06/26/pdo-and-extending-mysqli/) Reproduce code: --------------- $db = new mysqli(...); $teamId = some integer; $stmt = $db->prepare('SELECT * FROM teams where id=? LIMIT 1;'); if($stmt === FALSE) { die("Could not prepare statement"); } if($stmt->bind_param('i', $teamId) === FALSE) { die("Could not bind params"); } if($stmt->execute() === FALSE) { die("Could not execute statement"); } if(($result = $db->store_result()) === FALSE) { die("Could not store result (db)." . $db->error); } $teamAsArray = $result->fetch_assoc(); print_r($teamAsArray); Expected result: ---------------- I would expect the above code to have $teamAsArray be an associative array with the fields in my team table as the keys, and the values be the corresponding values. At the very least, I would expect an error to be thrown since it can't. I expect: Array ( [id] => 1 [name] => Nicaragua II [updateTime] => 2008-06-05 00:35:43 [meetings] => Saturdays at 10:00pm in the Mech Lab [country] => Nicaragua [currentProjectId] => 3) Actual result: -------------- An array full of garbage...but not senseless garbage, but rather the fields in the wrong spots, with some garbage mixed in between: Array ( [id] => [name] => [updateTime] => ��� [meetings] => Nicaragua II [country] => �#+ [currentProjectId] => Saturdays at 10:00pm in the Mech Lab ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=45289&edit=1
