初用面向对象经常碰到这种情况就是两个方法需要用到的数据一样比喻我在一个方法里从数据库里读取了一些数据分配到模板里然后我发现在同一个模块里的另一个方法也需要用到这些数据或者其中的某一个变量我就不知道该怎么办了求大湿说明白点哈小弟菜鸟

回复讨论(解决方案)

你可以在Comment/comment.php定义公共方法，任何地方都可以调用。

先写一个CommonAction继承thinkphp的Action,代码如下：

CommonAction extends Action{}

然后在用全部普通的action继承CommonAction，这样共用的方法写在CommonAction里边，然后在不同的子action中调用共用的方法。

在需要的方法里再写一遍
注意，一般情况下执行 display 方法就意味着程序结束了
同一控制器中的不同方法并不在同一http会话中执行，所以他们都是独立的。只不过被你写在了一起

如果在执行 display 方法之前，需要调用其他方法，而被调用的方法使用了与调用者相同的数据集
那么你可以把数据集的产生放在 init 方法中

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
