You can make use of array_keysto get all attributes from a model.
您可以使用array_keys来从模型中获取所有属性。
$users = Users::all();
$user = $users->first();
$attributes = array_keys($user->toArray());
Alternatively you can use this approachto get the column names based from a certain table in your database.
或者，您可以使用此方法从数据库中的某个表中获取列名。

Now you can just use the ->keys()method from a collection.
现在您可以只使用->keys()集合中的方法。
$fruits = collect(['orange' => 15, 'lemon' => 75]);
$keys = $fruits->keys();
// ['orange', 'lemon']
