There are two easy ways to accomplish this. The first is by concatenation like you were doing for the rest of the string:

<?php
function get_item_html($id,$item)
{
    echo $item["genre"];
    $output = "<ul><a href='#'><video src='" . $item["video"] . " ' alt='" . $item["title"] . "' />" . "<h4>" . $item["title"]. "</h4>" . "</a></ul>";
}
?>

The alternative is to just use the variables in the quotes which I think is cleaner.

<?php
function get_item_html($id,$item)
{
    echo $item["genre"];
    $output = "<ul><a href='#'><video src='{$item['video']}'> alt='{$item['title']}'/><h4>{$item['title']}</h4></a></ul> ";
}
?>

After that, all you need to do is keep in mind that you aren't returning the output variable in your function currently.

Edit: Added closing brackets

It is an error with your HTML and the way you have things like russian nesting dolls but at this point the PHP is functioning properly.

Try like this..

<?php
function get_item_html($id,$item)
{
    echo $item["genre"];
    $output = "<ul><li><a href='#'><h4>{$item['title']}</h4></a><video src='{$item['video']}' alt='{$item['title']}'/></li></ul> ";
}
?>

Now what you have is an unordered list with a list item and a link that includes your title which is closed, after that the video you're trying to load, then closing the list item and the unordered list.

It becomes this:

<ul>
    <li>
        <a href="#"><a href='#'><h4>{$item["title"]}</h4></a>
        <video src='{$item["video"]}' alt='{$item["title"]}'/>
    </li>
</ul>

versus this:

<ul>
    <a href='#'><video src='{$item["video"]}' alt='{$item["title"]}'/><h4>{$item["title"]}</h4></a>
</ul>

Try this

<h4> <?php echo $item["title"] ; ?> </h4>

This is called escaping php in html. Whenever u want to add any php between html tags, use <?php ?>. Let me know if this works !
