CodeIgniter: how to find out, $ this-> load-> database (); connected?

If I configure my CI application to use a database to handle the session, if the user identifier session returns false, I can assume that the user session has expired.

But what if the actual reason he returned false was because the database connection was not successfully established?

By default, CodeIgniter will be a fatal error if the database is loaded and cannot connect, but if you have:

$db['local']['db_debug'] = FALSE;

then he will not tell you. You can turn off debugging altogether, but still respond to a failed load by doing this:

if ( $this->load->database() === FALSE )
{
   exit('THE END IS NIGH!');
}

, , wokrs, , , - dbutil, .

$this->load->database();
$this->load->dbutil();

// check connection details
if( !$this->dbutil->database_exists('myDatabase'))
    echo 'Not connected to a database, or database not exists';

CI throws

A Database Error Occurred
Unable to connect to your database server using the provided settings.

or something like that if the connection fails
