So i've looked all over for information about this, and I found something that says that mysqli::get_result doesn't work for PHP 5.4 and below, but running phpinfo() says that im on 5.5. I'm running and Ubuntu LAMP server, and the whole code works just fine on my XAMPP on OSX. The following is the code in question:

<?php   
                if ($videos = $mysqli->prepare("SELECT htmlcode FROM content WHERE datatype = 'Video' AND username = ?")) {
                    $videos->bind_param('s',$_SESSION['username']);
                    $videos->execute();
                    $result = $videos->get_result();
                    while ($row = $result->fetch_array(MYSQLI_NUM))
                    {
                        foreach($row as $r) {
                            echo "$r";
                        }
                    }
                } else {
                        return false;
                }
            ?> 

Please help! Thanks.
