php - How to merge Laravel objects in controller

Question

I have a controller where I want to combine data from multiple tables with parallel structures. What I want to end up with in the end is one object I can return from the controller so I can parse it in Backbone.

I want to do something like this:

public function index()
{
    $mc = MainContact::where('verified', '=', '1')->get();
    $sm = SendMessage::where('verified', '=', '1')->get();

    $obj = (object) array_merge((array) $mc, (array) $sm);
    return $obj;
}

I'm told by another post on StackOverflow that this works in PHP 5.3+. However, this returns the following error in Laravel:

UnexpectedValueException: The Response content must be a string or object implementing
 __toString(), "object" given.

How do I implement this method in Laravel? Both $mc and sm return valid objects in Laravel.

Answer 1

现在你可以使用

$new_collection = $collection->merge($other_collection).

这在Laravel 4中有效，并且似乎可以处理数组和集合。

Answer 2

您可以在这里做的是合并两个查询结果的数组，然后使用带有 json 输出的响应，如下所示。

$array = array_merge($mc->toArray(), $sm->toArray());
return Response::json($array);

Answer 3

我们可以使用如下集合

$admins = User::where('type', '=', 'admin')->get();

$authors = User::where('type', '=', 'author')->get();

$admin_author_collection = $admins->merge($authors);

另外，请参考以下链接的各种收集方法

Answer 4

Route::get('test', function(){
    $rank = Rank::get();
    $policy = Policy::get();
    $obj = (object)array_merge_recursive((array)$rank , (array)$policy);
    var_dump($obj);
});

这对我有用。代替 array_merge 使用 array_merge_recursive()。

Answer 5

你可以简单地使用array_merge(firstObject,secondObject)函数。

$obj = array_merge($mc, $sm);
return $obj;
