Laravel Eloquent不适用于Cache

Question

I'm trying to cache a query in laravel in a model. My code was :

foreach(Building::where('village', '=', $village->id)->get() as $building)
            {

So I did it like this:

$buildingCache = Cache::remember('test123456', 60, function()
{
    return Building::where('village', '=', $id)->get();
});
foreach ($buildingCache as $bjdkfjksk)...............

And a strange error appears :

Undefined variable: id

But I'm sure this var is defined, I use it before...

Strange, isn't it?

If you use closure, you need to add use to use any variable inside closure this way:

$buildingCache = Cache::remember('test123456', 60, function() use ($id)
{
    return Building::where('village', '=', $id)->get();
});
