CodePudding user response：

This is called Conflict Resolution. In a simple terms, you need to select a default name method so to speak.

To resolve naming conflicts between Traits used in the same class, the insteadof operator needs to be used to choose exactly one of the conflicting methods.

All you need to need is to use A::name instead of the others. and define another names for the other trait methods.

class CRController extends Controller
{
    use A {
        A::name insteadof B,C,D;
        A::name AS A_name;
    }
    use B {
        B::name AS B_name;
    }
    use C {
        C::name AS C_name;
    }
    use D {
        D::name AS D_name;
    }
}
