How to merge Laravel objects in controller
提问by sehummel
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.
我有一个控制器，我想将来自多个表的数据与并行结构组合在一起。我最终想要的是一个我可以从控制器返回的对象，以便我可以在 Backbone 中解析它。
I want to do something like this:
我想做这样的事情：
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 StackOverflowthat this works in PHP 5.3+. However, this returns the following error in Laravel:
StackOverflow 上的另一篇文章告诉我，这适用于 PHP 5.3+。但是，这会在 Laravel 中返回以下错误：
UnexpectedValueException: The Response content must be a string or object implementing
__toString(), "object" given.
How do I implement this method in Laravel? Both $mcand smreturn valid objects in Laravel.
我如何在 Laravel 中实现这个方法？双方$mc并sm在Laravel返回有效对象。

What you can do here is merge the arrays of the two query result and then use the Response with json output like shown below.
您可以在这里做的是合并两个查询结果的数组，然后使用 Response 和 json 输出，如下所示。
$array = array_merge($mc->toArray(), $sm->toArray());
return Response::json($array);

We can use collection as below
我们可以使用集合如下
$admins = User::where('type', '=', 'admin')->get();
$authors = User::where('type', '=', 'author')->get();
$admin_author_collection = $admins->merge($authors);
Also, Please refer the various collection methods to below link
另外，请参考以下链接的各种收集方法

Route::get('test', function(){
$rank = Rank::get();
$policy = Policy::get();
$obj = (object)array_merge_recursive((array)$rank , (array)$policy);
var_dump($obj);
});
This is working for me. Instead of array_merge use array_merge_recursive().
这对我有用。使用 array_merge_recursive() 代替 array_merge。

You could simply use array_merge(firstObject,secondObject)function.
你可以简单地使用array_merge(firstObject,secondObject)函数。
$obj = array_merge($mc, $sm);
return $obj;
