        array("href" => "/blog/", "title" => "Blog"),
        array("href" => "/portfolio/", "title" => "Portfolio"),

    );
    $menu = "<ul>";
    $class = "";
    foreach ($pages as $page) {
       $class = ($page["href"] == $currentPage) ? ' class="current"' : '';
       $menu .= <<<HTML
<li{$class}><a href="{$page["href"]}">{$page["title"]}</a></li>
HTML;
    }
