Questions about namespace in binding facade

Encountered this problem when binding facade

//Successful binding
Facade::bind('app\index\facade\Human','app\index\ Common\Human');

Facade::bind('app\index\facade\Human','\app\index\Common\Human');

//Failed binding Define
Facade::bind('\app\index\facade\Human','\app\index\Common\Human');

Xiaobai wants to know why the app is in front of the binding \ cannot be added. Doesn’t it mean starting from the root?

This is just like you use the "use" keyword to alias the referenced class. The default is to start from the root space,
For example:

namespace test; use app\admin; // 与下面写法是完全一样的 namespace test; user \app\admin; // 默认就是全局空间开始查找

If you want to understand Facade::bind() parameter, you can view the source code of the Facade class. In the source code, there is a detailed description of the bind() method

reply Does it mean that although there is no \ in front, the search is actually starting from the root? Then I looked at the Facade source code and understood its binding mechanism. Thank you teacher!
