HomeBackend DevelopmentPHP Tutorial请教这个是异常抛出PHP中什么写法?是版本改进嘛?

请问下面这段代码是什么意思?是直接取对象的方法嘛?

throw new Exception\RuntimeException('Config is read only')

是不是所有的PHP都可以通过\直接取对象的方法,哪个版本改进的,谁能提供下相关资料

这个就是PHP的namespace特性,便于更好的组织代码结构,防止命名冲突,从5.3.0开始支持的,详见官方文档:
http://www.php.net/manual/en/language...

具体你的代码,调用的类结构如下:

namespace Exception;

class RuntimeException extends Exception{
    function xxx(){...}
}

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.
