Laravel cache does not store null value

Question

I'm using Laravel 5.2 and wants to cache eloquent results, but it does not store empty results (= null) on cache. Is there any way to do it?

return Cache::remember("cacheKey_{$id}", 120, function () use ($id) {
  return FooModel::where(...)->first();
});

When the result is not empty, the cache is working properly.

Laravel cache doesn't allow to store null values in cache but you can store false values.

    cache(['key' => null],120)
    var_dump(Cache::has('key')); //prints false
    cache(['key' => false],120)
    var_dump(Cache::has('key')); //prints true

So I would suggest you to try something like:

return Cache::remember("cacheKey_{$id}", 120, function () use ($id) {
  $your_check = FooModel::where(...)->first();
  return is_null($your_check) ? false : $your_check;
});

Alternatively you can assume that when there isn't the key, it would be null (check with Cache::has() or isset())
