Guys, why can this code get the user name? ! !

Question

I have a few questions:

1 Shouldn’t $user, the automatically loaded construct, be empty?

is to call $this->user->name in the hello method, so what you get is also empty.

Why is it written like this?

Answer 1

The parameter of the constructor method is required to be a userModel object. If this object has the attribute name, it can be $this->user->name.

Answer 2

An error will be reported. In the construction method, did you pass user in the new object (did you pass it in)?
