如何在Laravel中访问控制器内部的对象属性？

Question

Hello I wanted to know how to access and store a property of a gotten object in laravel controller and here is my code:-

 $phonebooks = Phonebook::with('client')->get();
    $test = $phonebooks->id;
    return view('admin.phonebooks.index', compact('phonebooks'))->with('current_time',$current_time);

Here I want to store the id property in $test variable but I get this error:- Property [id] does not exist on this collection instance.

Answer 1

Its a collection

$users = User::with('posts')->get();

then $userId = $users->id // this will always throw error

instead try doing this

foreach($users as $user) {
    dd($user->id);
}

Answer 2

$phonebooks is variable type of collection so you must acces each phonebook with foreach or just index. with foreach :

$i = 0;
foreach($phonebooks as $phonebook){
    $test[$i] = $phonebook->id;
    $i++;
}

or with defined index:

$test = $phonebooks[0]->id;

Answer 3

$phonebooks = Phonebook::with('client')->get(); This return instance of \\Illuminate\\Database\\Eloquent\\Collection .
For this case use

foreach ($phonebooks as $phonebook) {
    $test = $phonebook->id;
}

Or you must be get only one recorde in db using

$phonebooks = Phonebook::with('client')->first(); // if need some condition
$test = $phonebook->id;
