Question

I\'m new to Codeigniter PHP framework. When I\'m testing my application I get \'Unknown database db_name\' error. I have browsed through several sites but didn\'t found solu

Answer 1

I was getting same error when i installed new wampserver 3.2.0, it is an evil it installs MariaDB by default and port 3306 is assigned to it , you cannot even change it. I think codeigniter/php tries to connect to this port by default. I used following , it worked for me i.e. hostname => 'localhost:3308'

 $db['default'] = array(
        'dsn'   => '',
        'hostname' => 'localhost:3308',
        'username' => 'root',
        'password' => '',
        'database' => 'soft',
        'dbdriver' => 'mysqli',
        '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
    );
