如何写好一个PHP的类?

php but Write Several how of question

 

 

 

 

 

 

 

嗯,这是一个听起来很容易,但是实际操作起来并不容易的问题。前几天和一家公司的技术负责人聊PHP面向对象在公司内的应用,他的意思是:现在很少有PHPer懂面向对象。理由很简单,没有任何一个强制性的理由使你必须使用对象化的PHP。不仅如此,你要明白一件事,面向对象的门槛,不低,但PHP的门槛,很低。

 

我承认他说的没错,就我这几年的经验来看,很多人只了解到PHP class的基本语法,但是一些核心的思想,如:类的创建原则、设计模式等,这些理论知识的运用没有一定时间的经验是没法真正明白的。我们的困扰主要在以下几个地方:

 

1. 为什么要用

 

2. 门槛很高,如何坚持下来

 

3. 使用场景

 

4. 有什么好处,我可以使用过程的方法完成的事情,为什么非要使用对象的方法

 

很遗憾,每一本将面向对象的书都有答案。可是,我们真的能明白么?

 

刚好,我们在做课程类的产品,因此,我也计划通过实践的方式给出一门主要讲解在PHP环境下如何使用面向对象的课程。我期望这门课程可以非常容易上手,因此我也把它写得非常简单:

 

1. 介绍使用的环境

 

2. 每次通过实例讲解一个小的知识点

 

3. 所有的源码发布到github分享

 

4. 类库可以被直接使用,且定期更新

 

这是一个设想,当然也需要真正的实施。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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.

Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
