Kohana 3.3不使用MySQLi驱动程序

Question

I'm working on a project that uses Kohana 3.3. I've run into a problem where I want to connect to a database. The application is telling me it's using MySQL and it's decrepated.

To solve this I've downloaded a MySQLi driver for Kohana 3.3 and followed the instructions (creating a mysqli folder in the modules folder and adding a new line in bootstrap.php to enable it).

However when I try to perform any database actions it still says it's using MySQL. The error reads: "Database_Exception [ 8192 ]: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead".

The line I'm using to enable the module is 'mysqli' => MODPATH.'mysqli', // MySQLi support for Kohana

The MySQLi driver I'm using is this (links to github).

Can anyone see what's going wrong?

Thanks in advance.

Just enabling the module isn't enough.

Since Kohana 3.3 the autoloader is case sensitive, so MODPATH/mysqli/classes/kohana/database/mysqli.php should become MODPATH/mysqli/classes/Kohana/Database/MySQLi.php for example.

You have to edit your APPPATH/config/database.php and set the driver to 'MySQLi' or set Database::$default to the correct default database instance name. (The one using 'MySQLi' as the driver.)

And just to be sure, do NOT edit config files outside of APPPATH. Instead, copy the file to APPPATH and edit that file. You generally should not have to edit files outside of APPPATH. Updating modules to work with a new version is allowed of course. But config files outside of APPPATH should serve as examples/blueprints.
