How to Convert MySQL to MySQLi
The project above is a wrapper that allows you to use old php mysql code with the new cli driver
Find the download, its 4 small files,
I changed the name of mysql2i.class.php to mysql2i.class_helper.php and put it in \application\helpers\.
Loaded it \application\config\autoload.php
$autoload['helper'] = array('gj','mysql2i.class');
and it did a nice job of allowing me to use my old php mysql code
\application\config\database.php
$db['default'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => 'zCIDBclouda',
..
'dbdriver' => 'mysqli',
