Question

我有一个像这样的多维数组：

$sidebar_booking = array(
    'booking' => array(
        'levels' => array('1'),
        'title' => 'Booking',
        'icon' => 'fa-calendar',
        'sub' => array(
            'rates-availability' => array(
                'levels' => array('1'),
                'title' => 'Tariffe e Disponibilità',
                'sub' => array(
                    'booking-overview' => array(
                        'levels' => array('1'),
                        'title' => 'Panoramica',
                        'url' => '/ctrl/booking/overview/',
                    ),
                    'booking-setup' => array(
                        'levels' => array('1'),
                        'title' => 'Setup Camere / Tariffe',
                        'url' => '/ctrl/booking/setup/',
                    ),
                    'booking-prices' => array(
                        'levels' => array('1'),
                        'title' => 'Modifica Prezzi',
                        'url' => '/ctrl/booking/prices/',
                    ),
                    'booking-availability' => array(
                        'levels' => array('1'),
                        'title' => 'Modifica Disponibilità',
                        'url' => '/ctrl/booking/availability/',
                    ),
                    'booking-openclose' => array(
                        'levels' => array('1'),
                        'title' => 'Apri / Chiudi Camere',
                        'url' => '/ctrl/booking/openclose/',
                    ),
                    'booking-restrictions' => array(
                        'levels' => array('1'),
                        'title' => 'Restrizioni',
                        'url' => '/ctrl/booking/restrictions/',
                    ),
                    'booking-rates' => array(
                        'levels' => array('1'),
                        'title' => 'Tariffe',
                    ),
                ),
            ),
            'booking-promo' => array(
                'levels' => array('1'),
                'title' => 'Promozioni',
                'url' => '/ctrl/booking/promo/',
            ),
            'booking-reservations' => array(
                'levels' => array('1'),
                'title' => 'Prenotazioni',
                'url' => '/ctrl/booking/reservations/',
            ),
        )
    ),
);

我用它来创建我的（嵌套）侧边栏菜单

现在，给定一个匹配上例中url之一的字符串，我想使用title s

构建面包屑

即，给定字符串/ctrl/booking/prices/我想获得以下列表（然后我可以使用CSS转换为breadcrumb）：

预订
TariffeeDisponibilità
Modifica Prezzi

（你看我在数组中向后移动，查找标题;请注意，最后一项与url相关联）

我真的被困在上面，这超出了我的技能:-（
提前谢谢！

Answer 1

您可以尝试这样

for(LatLng point : new LatLng[]{POINTA, POINTB, POINTC, POINTD}) {
        target.setLatitude(point.latitude);
        target.setLongitude(point.longitude);
        if(location.distanceTo(target) < METERS_100) {
            // bingo!
        }
    }

Answer 2

编辑版

function getTitle(Array $arr, $find) {
    foreach($arr as $val){
        if (isset($val['url']) && $val['url'] == $find) {
            return '<li><a href="' . $val['url'] . '">' . $val['title'] . '</a></li>';
        }
        if (isset($val['sub'])) {
            return '<li>' . $val['title'] . '</li>' . getTitle( $val['sub'], $find);
        }
    }
    return false;
};
