How to implement simple Facades in php?

Question

namespace Model\TestModel;

class User

    public function get()
    {
        return '爱因斯坦';
    }
}

I want to implement the same usage as Laravel Facades, load.phpHow to write it?

You need to implement a Facade object yourself to proxy all method calls to the real object.

class UserFacade
{
    private $user;

    public function __constructor()
    {
        $this->user = new User();
    }

    public function __callStatic($name, $arguments)
    {
        return call_user_func_array(array($this, $name), $arguments);
    }
}

$user UserFacade::get();

Any static method call to UserFacade will be proxied to User. __callStatic is triggered when there is a static call. The passed parameter $name is the method name of UserFacade::get static call, and $arguments is the array of parameters.

Laravel official description Facade is a concise and easy-to-remember class call. Laravel basically provides the Facade class for its features. At the level of business development, I do not recommend the design method of static class calling. I will open a separate post to discuss this.
