    set_time_limit(0); // We dont want the script to time out
    require_once ‘engine/start.php’;
    // Load configuration
    global $CONFIG;
    $dbhost = ‘localhost‘; // The MySql Hostname
    $dbuser = ‘root‘; // MySQL Username
    $dbpass = ‘yourpassword‘; // MySQL Password
    $conn = mysql_connect($dbhost, $dbuser, $dbpass, TRUE) or die (‘Error connecting to mysql’); // TRUE so we dont overwrite connection
    $dbname2 = ‘mydatabase‘; // The databasename
    mysql_select_db($dbname2);
    $sql=”SELECT title,contents FROM pages“; // Get the content from the source database
    $result=mysql_query($sql);
    // Go through the records and create what you need from that
    while ($row=mysql_fetch_array($result)) {
    $title=$row["title"]; //Set the title value from the mysql title field
    $content=$row["contents"]; // Same as above but for contents
    gatekeeper();

    }
    }
    // Validate create
    $page->title = $title;
    if (!$page->title)
    {
    register_error(elgg_echo(“pages:notitle”));
    forward($_SERVER['HTTP_REFERER']);
    exit;
    }
