<li>Science Fiction</li>
<li>Special Interest</li>
<li>Sports</li>
<li>Thriller</li>
<li>War</li>
<li>Westerns</li>
</ul>

Answer 1

One way to accomplish this is to use query strings to form a url based off your base url.
http://domain.tld/index.php?genre=crime
index.php
if ($_GET['genre'] == 'crime') {
// display crime genre
} else {
// display index
}
You'll also want to include some validation/error checking when you're doing this. You can check whether or not the genre param is set using isset(). It is also important to escape the input to 'genre' so that injection attacks are less likely.

Answer 2

To generate the links and change page content all in one go, you can try:
<?php
$actions = array("Action", "Art and Experimental", "Comedy", "Crime and Mystery", "Documentary", "Drama", "Epic and Historical", "Family", "Fantasy", "Foreign", "Horror", "Live Performances", "Musicals", "Romance", "Science Fiction", "Special Interest", "Sports", "Thriller", "War", "Westerns");
?>
<ul class="snav">
<?php
foreach($actions as $action) {
$url_token = str_replace(' ', '_', strtolower($action));
echo '<li>' . $action . '</li>';
}
?>
</ul>
<?php
$genre = $_GET['genre'];
switch ($genre) {
case 'action':
echo 'Woo Action!';
break;
case 'drama':
echo 'GASP!';
break;
case 'art_and_experimental':
echo 'Weird...';
break;
default:
echo 'There is no action called ' . $genre . ' :(';
}
?>
This will generate html of the form:
<ul class="snav">
<li>Action</li>
<li>Art and Experimental</li>
...
</ul>

Answer 3

You're going to have to use $_GET variables using PHP and have something like:
Links look like
Action
PHP file:
if (isset($_GET['genre'])) {
switch ($_GET['genre']) {
case 'action':
echo 'something here';
break;
case 'horror':
echo 'something here';
break;
//etc
}
}
or you could use jQuery to dynamically load the data into the page.
Hope this helps!
