If you just want to display a menu for a known set of pages without re-architecting your current code, how about this:

<?php
$pages = array(
    'index.php' => 'Home',
    'about.php' => 'About',
    'contact.php' => 'Contact',
    'faq.php' => 'FAQ',
    'tutorials.php' => 'Tutorials',
) ;

$currentPage = basename($_SERVER['REQUEST_URI']) ;

?>

<div id="menu">
    <ul id="menuList">
        <?php foreach ($pages as $filename => $pageTitle) { 
            if ($filename == $currentPage) { ?>
        <li class="current"><?php echo $pageTitle ; ?></li>
            <?php } else { ?>
        <li><a href="<?php echo $filename ; ?>"><?php echo $pageTitle ; ?></a></li>
            <?php
            } //if 
         } //foreach 
            ?>
    </ul>
</div>

Put this in its own file, say menu.php, and then include it in each page. Then you can style your menu with CSS.

i agree with the first solution even if its a bit simply. For me you have to split your website into some script where you include your navigation script like the second solution.

but if you really want to make a dynamic navigation, your data cant be write in a file and they are stock in a database or on an xml file.... to do that you have to create a class or a function who parse your data and create array like first solution.

 /* header.php (main header template)*/
<html>
<head>
...
</head>
<body>
     <div id="mainMenu">
          <?php echo Navigation::getNav($databaseCnx);?>
     </div>

and in another script you have to create a class who manage the data

<?php 
class Navigation{
    static function getNav($cnx){
         $menuList = '<ul>';
         $dataFromDataBase = $cnx->getArray('MySqlRequest');

         foreach($dataFromDataBase as $menu) {
              $menuList  .='<li><a href="'.$menu->uri.'">'.$menu->name.'</a></li>';
         }

         $menuList .= '</ul>';

         return $menuList;
    }
}

i write it fast but i hope i can help some who look for tips to create dynamic menu.

It seems that you want to include a menu file in all your pages. You can use include().

In all your pages:

<html>
  <body>
    <?php include('navigation.php'); ?>

    Contents of this page here...

  </body>
</html>

And in navigation.php:

<div id="mainmenu">
  <a href="home.php">Home</a> | <a href="about.php">About</a> | etc...
</div>

This way you can update your navigation menu just once for all your pages.
