KnpMenu

The KnpMenu library provides object oriented menus for PHP 5.3.
It is used by the KnpMenuBundle for Symfony2 but can now be used stand-alone.

<?php

use Knp\Menu\MenuFactory;
use Knp\Menu\Renderer\ListRenderer;

$factory = new MenuFactory();
$menu = $factory->createItem('My menu');
$menu->addChild('Home', array('uri' => '/'));
$menu->addChild('Comments', array('uri' => '#comments'));
$menu->addChild('Symfony2', array('uri' => 'http://symfony-reloaded.org/'));
$menu->addChild('Coming soon');

$renderer = new ListRenderer();
echo $renderer->render($menu);

The above menu would render the following HTML:

<ul>
  <li class="first">
    <a href="/">Home</a>
  </li>
  <li class="current">
    <a href="#comments">Comments</a>
  </li>
  <li>
    <a href="http://symfony-reloaded.org/">Symfony2</a>
  </li>
  <li class="last">
    <span>Coming soon</span>
  </li>
</ul>

This way you can finally avoid writing an ugly template to show the selected item, the first and last items, submenus, ...

The bulk of the documentation can be found in the doc directory.

Installation

KnpMenu does not provide an autoloader but follow the PSR-0 convention. You can use any compliant autoloader for the library, for instance the Symfony2 ClassLoader component. Assuming you cloned the library in vendor/KnpMenu, it will be configured this way:

<?php
$loader->registerNamespaces(array(
    'Knp\Menu' => __DIR__.'/vendor/KnpMenu/src'
    // ...
));

What now?

Credits

This bundle was originally ported from ioMenuPlugin, a menu plugin for symfony1. It has since been developed by knpLabs and the Symfony community.
