It is recommended that you use dd(AdminUser::find(1)) to print it out and see. The structure is very clear

This is a single row of data. Is there something wrong? It’s just that the data exists in the form of objects. If you want it to be in the form of an array, you need to follow the toArray method. If you need json, follow the toJson method.

Return the AdminUser object, which is your
class AdminUser extends Model
so that you can easily use AdminUsercustomized and inherited methods from Model
__get and have been defined in Model __set, If you just need to get the attributes, you can also get the value directly
$adminUser->id like a normal object.

Laravel is very powerful, so database queries generally do not directly return an ordinary object or array. These are all to facilitate us to perform some possible subsequent operations. Just don’t be scared by him at the beginning, you will find that it’s really fun after you use it a lot~!
