<?php
// Now create a function that will highlight the section you are in:
function create_highlighted_sections($secarray) {
    // Loop over the entire array, making a basic menu:
    echo "<ul>\n";
    foreach ($secarray as $section => $url) {
        // Echo out a link for this section, highlighting if currently in it
        $class = '';
        if (strncmp($url, $_SERVER['PHP_SELF'], strlen($url)) == 0) {
            $class = ' class="current"';
        }
        echo "<li{$class}><a href=\"{$url}\">{$section}</a></li>\n";
    }
    echo "</ul>\n";
}    

// An array with all section names and the URL to their top directory:
$sections = array(
    'News' => '/news/',
    'Photos' => '/media/pictures/',
    'Video' => '/media/movies/',
    'Stuff' => '/eliw/'
    );

// Output a little bit of CSS to accomplish the highlighting:
?>
<style>
.current, .current a { color: red }
</style>
<?php
// And call the function to test it:
create_highlighted_sections($sections);
?>
