Log threshold and environment

You can use something like this :

PHP Code:

switch (ENVIRONMENT)
{
    case 'development':
        $config['log_threshold'] = 2; // Debug
        break;

    case 'testing':
        $config['log_threshold'] = 1; // Error
        break;

    default:
        $config['log_threshold'] = 0; // Disabled
        break;
}
