I understand that mysqlnd allows non blocking queries. However, I'm trying:
// goes without saying this code works correctly when second parameter is ommitted
$link->query($myQuery, MYSQLI_ASYNC);
The error I get is:"Notice: use of undefined constant MYSQLI_ASYNC assumed 'MYSQLI_ASYNC' " and ensuing errors.
PHP Version: 5.3.5-1 ubuntu7.4
I don't know if I actually have mysqlnd installed/activated, and I can't find a good resource on how to tell if it is.
Help?
The most likely cause for this is that the mysqlnd extension is not installed. Please note, according to docs any PHP version less than PHP 5.4 will need to explicitly configure to use mysqlnd; starting with PHP 5.4 mysqlnd will be enabled by default.
ReplyDeleteThere are a couple different ways to tell if you have an extension loaded.
phpinfo() should output a section labeled mysqlnd
extension_loaded('extension_name') should return true/false whether or not you have the extension loaded
