“非法偏移类型”突然出现在注册数组 Laravel 中

'Illegal Offset Type" suddenly occurring in registration array Laravel

提问by user2480176

In my registration store function which is called after the user has typed in valid information I have a default array that is converted to JSON and stored in my DB with the user. All of a sudden I am getting the error:

在用户输入有效信息后调用的注册存储函数中，我有一个默认数组，该数组被转换为 JSON 并与用户一起存储在我的数据库中。突然间我收到错误消息：

Illegal Offset Type (line 50)

which the last object of my first array (it is multi dimensional). I deleted the object to see if the error was specific to that object but the error still persists. I don't understand where this error is coming from because I did't change anything in or around the registration system for a while.

这是我的第一个数组的最后一个对象（它是多维的）。我删除了该对象以查看错误是否特定于该对象，但错误仍然存​​在。我不明白这个错误是从哪里来的，因为我有一段时间没有改变注册系统内部或周围的任何东西。

This is the store() function being called after the registration form is submitted:

这是提交注册表后调用的 store() 函数：

public function store()
{
    $input = Input::only('username', 'email', 'password', 'password_confirmation');

    $this->registrationForm->validate($input);

    $user = User::create($input);

    $arr = array(
        [1] => array(
            'name' => 'Apple',
            'time' => '2:00 am',
            'date' => '10.26.96',
            'symptom' => false,),
        [2] =>array(
            'name' => 'Banana',
            'time' => '3:56 pm',
            'date' => '10.26.96',
            'symptom' => false,),
        [3] =>array(
            'name' => Input::get('symptom'),
            'time' => '4:45 pm',
            'date' => '10.26.96',
            'symptom' => true,
        ));

    $user->json = json_encode($arr);

    $user->save();

    Auth::login($user);

    return Redirect::home();
}

The error occurs in "line 50" which is in the last object of the first array 'symptom' => false,),

错误发生在第一个数组的最后一个对象中的“第 50 行” 'symptom' => false,),

I have absolultley no idea how this happened. I even used time machine to load my project from a few days ago when I am certain it was fully functional and the error is still there. I will appreciate any help, please let me know if more information is needed.

我绝对不知道这是怎么发生的。我什至使用时间机器从几天前加载我的项目，当时我确定它功能齐全并且错误仍然存​​在。我将不胜感激，如果需要更多信息，请告诉我。

arrayinitialization syntax only accept key names as a plain scalar values, thus having ['foo']syntax is incorrect in this case.

array初始化语法只接受键名作为普通标量值，因此['foo']在这种情况下语法是不正确的。
