In laravel ->get();returns the collection object, you should user ->toArray()here.
在 laravel->get();返回集合对象，你应该->toArray()在这里使用。

$isConnectedM and $isConnectedA is Collection object.
Response::json($collection,200);automatic collection object to json conversion
$isConnectedM 和 $isConnectedA 是 Collection 对象。
Response::json($collection,200);自动收集对象到json转换
$MergeArray = $isConnectedM->merge($isConnectedA) ;
$resultArray = ['status' => 1, 'message' => 'Template uploaded!', 'dataArray' => $MergeArray];
return Response::json($resultArray,200);

@shahzad, Reason for the issue for array_merge we've to pass two arrays, if we didn't pass then it will throw an error.
@shahzad，array_merge 问题的原因我们必须传递两个数组，如果我们没有传递，那么它会抛出一个错误。
public function isConnectedMA() {
$user_id = Auth::user()->id;
// If user id is not passed, return or redirect to login page.
if (empty($user_id) {
// TODO : Do logic to retun
$resultArray = ['status' => 0, 'message' => 'OOPS! seems like user is not logged in.', 'dataArray' => []];
return Response::json($resultArray, 401);
}
$isConnectedM = DB::table('user_mlc_mailchimp')->where('user_id', $user_id)->get()->toArray();
$isConnectedA = DB::table('user_mlc_aweber')->where('user_id', $user_id)->get()->toArray();
$MergeArray = array_merge($isConnectedM,$isConnectedA); // array_merge((array)$isConnectedM, (array)$isConnectedA);
$resultArray = ['status' => 1, 'message' => 'Template uploaded!', 'dataArray' => $MergeArray];
return Response::json($resultArray,200);
}

$isConnectedMand $isConnectedAare not arrays. You can also use typecastto convert an objectto array.
$isConnectedM并且$isConnectedA不是arrays。您还可以使用typecast将 an 转换object为array.
$isConnectedM = (array) DB::table('user_mlc_mailchimp')->where('user_id', $user_id)->get();
$isConnectedA = (array) DB::table('user_mlc_aweber')->where('user_id', $user_id)->get();
