Codeigniter: Using PDO instead of mysql

Question

Until Codeigniter implements the use of PDO, is there a way to use hack it into CI that's stable and secure? Currently, instead of using the db driver, I'm using a model instead which has all my PDO code like prepare, fetch, execute, etc. in it. What are the rest of you doing?

Answer 1

On CodeIgniter 2.1.4+ using MySQL databases (Edit the file: /application/config/databases.php).

To use PDO:

$db['default']['hostname'] = 'mysql:host=localhost';
$db['default']['dbdriver'] = 'pdo';

To use MySQLi

$db['default']['hostname'] = 'localhost';
$db['default']['dbdriver'] = 'mysqli';

Answer 2

$active_group = 'default';
$query_builder = TRUE;

$db['default'] = array(
    'dsn'   => 'mysql:host=127.0.0.1; dbname=****yourdatabasename*****; charset=utf8;',
    'hostname' => '',
    'username' => 'root',
    'password' => '******yourpassword*******',
    'database' => '',
    'dbdriver' => 'pdo',
    'dbprefix' => '',
    'pconnect' => FALSE,
    'db_debug' => (ENVIRONMENT !== 'production'),
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array(),
    'save_queries' => TRUE
);
