初学PHP构造方法,有这样一个简单的构造方法问题,请教如下:
<code>class Name{ //成员属性 public $name; //构造方法 public function __construct($name = 'php'){ $this->name = $name; } } </code>
请解释一下:$this->name = $name; 这句怎么理解,是将$name的收到或者初始化的值赋给本类中的$name吗?还是怎么理解,非常感谢。

是,Name::$name
是类属性,实例出来的话就是对象属性。
new Name('php') 会创建一个 Name 的对象(或者叫做实例),将这个对象的 name 属性设置为 'php'

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.

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.
