php - array_merge() : Argument #1 is not an array in laravel 5. 5

Question

我遇到了一些问题，这是关于 laravel 中的 array_merge 我的 Controller 代码方法:

    public function isConnectedMA()
{
    $user_id = Auth::user()->id;
    if(!empty($user_id)) {
        $isConnectedM = DB::table('user_mlc_mailchimp')->where('user_id', $user_id)->get();
        $isConnectedA = DB::table('user_mlc_aweber')->where('user_id', $user_id)->get();
    }
        $MergeArray = array_merge($isConnectedM,$isConnectedA);
    $resultArray = ['status' => 1, 'message' => 'Template uploaded!', 'dataArray' => $MergeArray];
    return Response::json($resultArray,200);

}

我遇到的错误是

array_merge(): Argument #1 is not an array

我不知道我哪里错了 任何帮助将不胜感激!

使用toArray()将集合转换为数组

$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();
