Answer 1

You can make use of array_keys to get all attributes from a model.

$users = Users::all();
$user = $users->first();
$attributes = array_keys($user->toArray());

Alternatively you can use this approach to get the column names based from a certain table in your database.

Answer 2

Now you can just use the ->keys() method from a collection.

$fruits = collect(['orange' => 15, 'lemon' => 75]);

$keys = $fruits->keys();

// ['orange', 'lemon']
