The get_item_html function shows this. It outputs each item into it's own list using <li></li> which includes the image, title, and also a href link. 

function get_item_html($item) {
    $output = "<li><a href='details.php?id="
            . $item["media_id"] . "'><img src='"
            . $item["img"] . "' alt='"
            . $item["title"] . "' />"
            . "<p>View Details</p>"
            . "</a></li>";
    return $output;
}

'details.php?id=" . $item["media_id"] . The string after the ? and before the = is the $_GET. $_GET['id']

I'm a little confused by the question, but I think you are asking how a link would be programmed to generate a string in the URL to retrieve the appropriate data? If that's the case, then I think if the next few videos in that series should answer your question as you will build up links for the pagination.
