In my previous question I wrongly considered only one [sub] key, but the whole sidebar menu is this:

$sidebar = array(
    'dashboard' => array(
        'levels' => array('1', '2'),
        'title' => 'Bacheca',
        'icon' => 'fa-dashboard',
        'url' => '/ctrl/dashboard',
    ),
    'settings' => array(
        'levels' => array('1'),
        'title' => 'Impostazioni',
        'icon' => 'fa-gear',
        'sub' => array(
            'configuration' => array(

                'url' => '/ctrl/configuration',
            ),
            'languages' => array(
                'levels' => array('1'),
                'title' => 'Lingue',

                'levels' => array('1'),

                'url' => '/ctrl/agents',
            ),
        ),
    ),
);

As you can see, [sub]s can be nested
The question is still that: given a string matching one of the url in the above example, I would like to build the breadcrumbs using the titles

I.e, given the string /ctrl/booking/prices/ I'd like to get the following list (I can then convert to breadcrumb with CSS):

Booking
Tariffe e Disponibilità
Modifica Prezzi

(you see I go backward in the array, finding titles; note that last item is linked to url)

Please, any help?

I tried this answer stackoverflow.com/a/33077286/160044 but it doesn't take care of multiple nested 'sub' keys and it stops at the first occurrency — Ivan

I edited your answer:

function getTitle(Array $arr, $find, $firstLevel = true) {
    $resultArray = array();
    foreach($arr as $val){
        if (isset($val['url']) && $val['url'] == $find) {
            return array('<li><a href="' . $val['url'] . '">' . $val['title'] . '</a></li>');
        }
        if (isset($val['sub'])) {
            $result = getTitle( $val['sub'], $find, false);
            if($result){
                $resultArray = array_merge($result);
                $resultArray[] = '<li>' . $val['title'] . '</li>';
                if(!$firstLevel){
                    return $resultArray;
                }
            }
        }
    }
    if(count($resultArray)){
        return implode(array_reverse($resultArray));
    }
    return false;
};

Example of usage:

echo getTitle($sidebar, '/ctrl/booking/prices');

Result:

Booking

Tariffe e Disponibilità

Modifica Prezzi

Example of usage 2:

echo getTitle($sidebar, '/ctrl/categories');

Result 2:

Impostazioni

Categorie
