If you want to embed code in a list, you'll need to [precede it with 8 spaces][1] instead of the usual 4:

* `include/db.php`:
        <?
        include_once 'include/config.php';
        
        try {
        
                $attribs =  
                        array(
                                PDO::ATTR_PERSISTENT => $config['db']['persistent'],
                                PDO::ATTR_ERRMODE => $config['db']['errormode']
                        );
        
        
                $db = new PDO(
                        $config['db']['uri'],
                        $config['db']['user'],
                        $config['db']['pass'],
                        $attribs
                );
                $db->query("SET NAMES 'utf8'");
                $db->query("SET CHARACTER SET 'utf8'");
        
        } catch (PDOException $e) {
                print "Error!: " . $e->getMessage() . "<br/>";
                die();
        }
        
        function dbGetEngine() {
                global $config;
                return substr($config['db']['uri'], 0, strpos($config['db']['uri'], ':'));
        }
        ?>


* `include/config.php`:
        <?
        
        //$config['db']['uri'] = 'sqlite:' . realpath('.') . '/site.db'; // PDO's database access URI
        $config['db']['uri'] = 'mysql:host=localhost;dbname=sitedb'; // server should be : 195.78.32.7
        //$config['db']['uri'] = 'pgsql:host=localhost;dbname=sitedb';
        $config['db']['user'] = 'user_goes_here'; // database username
        $config['db']['pass'] = 'pass_goes_here'; // database password
        $config['db']['persistent'] = false; // should the connection be persistent
        $config['db']['errormode'] = PDO::ERRMODE_EXCEPTION; // PDO's error mode
        
        ?>
