Multidimensional array Laravel 5.4

Question

I have been stuck with this problem for quite some time now. I have this particular array with the help of laravel's Socialite.

"first_name" => "xxx"
"last_name" => "xx"
"email" => "xxx@gmail.com"
"work" => array:2 [▼
  0 => array:4 [▼
    "employer" => array:2 [▼
      "id" => "xxxxxxxxxxxxxx"
      "name" => "FBI"
    ]
    "location" => array:2 [▶]
    "start_date" => "0000-00"
    "id" => "496298904045521"
  ]
  1 => array:6 [▶]
]

What I wanted to do is to get the first_name , last_name , email and the name from work and save it in the database after. The problem is I can't seem to retrieve the name of work but instead gives me this error message

(1/1) ErrorException Undefined index: employer

How can I make this work? Quite lost here.

Controller

public function handleProviderCallback()
{
    $usersocialite = Socialite::driver('facebook')->fields([
        'first_name', 'last_name', 'email', 'work'
    ])->user();

    //dd($usersocialite);
   $findUser = Fbuser::where('email',$usersocialite->email)->first();

    if ($findUser) {
        Auth::login($findUser);
        return view('home');
    }else{
        $user = new Fbuser;
        $user->first_name = $usersocialite->user['first_name'];
        $user->last_name = $usersocialite->user['last_name'];
        $user->email = $usersocialite->user['email'];
        $work=$usersocialite->user['work'];
        $w = collect([$work=>[$usersocialite->user['employer']=>[$usersocialite->user['name']]]]);
        $flattened = $w->flatten();
        $flatten->all();
        $user->work = $usersocialite->user[$flatten];
        $user->save();
        Auth::login($user);
        return view('home');
    }

}

Answer 1

you are accessing employer name in wrong way. you skip some indexes:

$w = collect([$work=>[$usersocialite->user['work'][0]['employer']=>[$usersocialite->user['work'][0]['employer']['name']]]]);

I can not understand what are you doing really. but I think you want something like this:

$w = collect(['work'=>[$work[0]['employer']=>[$work][0]['employer']['name']]]]);

Answer 2

To access the work name in the multidimensional array you can use something like this:

$user->work = $usersocialite->user['work'][0]['employer']['name'];

or you can use the Laravel helper function array_get :

$user->work = array_get($usersocialite->user, 'work.0.employer.name');

The line above will replace the code:

 $work=$usersocialite->user['work'];
 $w = collect([$work=>[$usersocialite->user['employer']=>[$usersocialite->user['name']]]]);
 $flattened = $w->flatten();
 $flatten->all();
 $user->work = $usersocialite->user[$flatten];
