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.

Installation

KnpMenu uses Composer, please checkout the composer website for more information.

The simple following command will install knp-menu into your project. It also add a new entry in your composer.json and update the composer.lock as well.

$ composer require 'knplabs/knp-menu:~2.0'

KnpMenu follows the PSR-0 convention names for its classes, which means you can easily integrate knp-menu classes loading in your own autoloader.

Getting Started

<?php

// Include dependencies installed with composer
require 'vendor/autoload.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(new \Knp\Menu\Matcher\Matcher());
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.
