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

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

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

composer require knplabs/knp-menu

KnpMenu follows the PSR-4 convention names for its classes, which means you can easily integrate knp-menu classes loading in your own autoloader.

<?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', ['uri' => '/']);
$menu->addChild('Comments', ['uri' => '#comments']);
$menu->addChild('Symfony', ['uri' => 'http://symfony.com/']);
$menu->addChild('Happy Awesome Developers');

$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.com/">Symfony</a>
  </li>
  <li class="last">
    <span>Happy Awesome Developers</span>
  </li>
</ul>

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

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