Zend Framework 2 navigation menu to array dehydration view helper

Sometimes you need to customize Zend Framework navigation menu output. For instance change <ul><li> output to <div><span>. This is impossible with Zend\View\Helper\Navigation\Menu because its HTML output isn't much customizable (only things like class, indent etc.). Such customization is possible with "partial" script, but my solution is to write a view helper that utilizes navigation menu to array dehydration.

Helper:

<?php
//<YOUR_MODULE>/View/Helper/NavigationMenuDehydrate.php
namespace <YOUR_MODULE>\View\Helper;

use Zend\View\Helper\AbstractHelper;
use RecursiveIteratorIterator;

class NavigationMenuDehydrate extends AbstractHelper
{
    
    protected $container;
    
    public function __invoke($container = null)
    {
        $this->container = $container;
        return $this;
    }
    
    public function dehydrate()
    {
        $array = array();
        $iterator = new RecursiveIteratorIterator($this->getView()
        ->navigation($this->container)->getContainer(), RecursiveIteratorIterator::SELF_FIRST);
        foreach ($iterator as $entry) {
            //TODO depth support
            $params = array(
                    'isActive' => $entry->isActive(true),
                    'label' => $entry->getLabel(),
                    'href' => $entry->getHref(),
            );
            $array[] = $params;
        }
        return $array;
    }
    
}

Add to your module config:

    'view_helpers' => array(
        'invokables' => array(
            'navigationmenudehydrate' => '<YOUR_MODULE>\View\Helper\NavigationMenuDehydrate' 
        )
    )

Use in your template like this:

foreach ($this->navigationMenuDehydrate('navigation')->dehydrate() as $entry) ...
