设计模式 - 如何用PHP实现一个类似插件中心的类?
有个php的config文件,里面用保存了一些类名
怎么写一个类,把这个config文件中的类new出来,同时去调用他们的run方法(这些类还不存在,后期再陆续补充,但是所有类都有一个run方法)?
我想给这些类的run方法传一个值,所有的这些run方法执行完成后,返回给我处理完的一个值,这种怎么弄?
这个需求,有点像插件一样,插件有些规则,有个插件中心的类,专门处理这些插件的调用,传值

你需要的是interface
和spl_autoload_register
,先设置一个interface,要求必须实现run
方法,然后规定一个类命名规则比如必须Plugin结尾,以及类文件的加载规则比如必须都放置在plugin目录,然后通过spl_autoload_register
注册加载逻辑即可
<code>interface IPlugin { public function run(); } class DemoPlugin implements IPlugin { public function run(){ //do sth return 'this is demo'; } } spl_autoload_register(function($class){ if($class是Plugin结尾){ include 'plugin/' . $class . '.php'; } });</code>

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
