thinkphp cross-module calling method

How do we call across modules in thinkphp?

During the development process, methods of other modules are often called in the current module. This involves cross-module calls. We can also learn about the use of two shortcut methods, A and R.

$User = A("User"); // 实例化UserAction控制器对象
$User->importUser(); // 调用User模块的importUser操作方法

The A("User") here is a shortcut method, which is equivalent to the following code:

import("@.Action.UserAction");
$User = new UserAction();

In fact, in this example, there is a simpler call than the A method Methods, for example:

R("User","importUser"); // 远程调用UserAction控制器的importUser操作方法

The above is only called in the current project. If you need to call methods between multiple projects, the same can be done:

$User = A("User","App2"); // 实例化App2项目的UserAction控制器对象
$User->importUser(); 
// 远程调用App2项目的UserAction控制器的importUser操作方法
R("User","importUser","App2");

An example of mine:

A project is divided into two groups: admin and home

home is the group by default:

When instantiating the module (the current location is the IndexAction class in admin Instantiated in the index method)

 import("@.Action.Home.UserAction");
$User=new UserAction();
$User->show();
$User->add();

Note: The method called must be public
