推荐答案

将对象保存在变量中并执行foreach循环，

save the object in a variable and do a foreach loop,

foreach($cart as $item) {
    echo $item->name;
    echo $item->options->brand;
}

如果这不起作用，则可以使用collection类中的fetch方法.

if that's not working, you can use the fetch method from the collection class.

http://laravel.com/api/5.0/Illuminate/Support/Collection.html#method_fetch

$item->fetch('name');

，并且您使用的软件包具有替代方法search

and the package you're using has a alternate method search

$item->search('name');
$item->search(['options' => 'name'])
