程序员 - 如何看懂一个面向对象的PHP程序

php yii programmer programming

比如YII框架,比如基于YII框架写的程序。或者其它的PHP程序。

我是一个小白,工作过三个月,用过ThinkPHP,Laravel写过简单的小网站。
现在在学YII框架,在看一个YII框架写的网站,各种新奇的PHP运用和众多的类、对象。不知道该如何学起。

有比从index.php,把所引用的文件、类一个一个看懂看明白,更科学的方法吗?或许,需要有足够的道行才能开始研究一个框架?
目前,不知道该怎么长进自己的技术。目前在研究 wordpress typecho 等PHP程序,是否是一个好方法呢?有什么好的建议有助于学习呢?

硬着头皮看源码 多花点时间把流程走一遍绝对值得 我当初就这么看的ZendFramework的源码 花了几个月 看懂之后再看其他的源码 都能领会意思 包括JAVA等其他语言的框架源码 其实都差不多 只是不同的语言而已

是的,就是从index.php看进去。
一个页面的执行,都是从index开始的,跟着index走,走完一个页面执行的全部流程。

我觉得看一遍 typecho 源码是个不错的选择,可以借鉴下别人阅读代码的经验。比如 @兜兜 写得文章:

你首先要了解这类框架的运行机制,然后需要对框架文件存放路径进行了解,明确文件名和方法命名规则,再然后就是读代码。。。
除此之外,即便是天才,也需要静下心来,仔细的研究一个框架的架构,并且对他各种特性进行使用练习,
这天底下的事情,做到没有用,因为你下一次可能就做不到了,情况不同,你也就是横看成岭侧成峰了
学到和知道更没有用,唯有练习最有用,只有不断的练习才能够发现自己明白的越来越多

其实目前大部分php程序都是面向对向的,建议找一个小点程序通读一下代码。

如果是框架的话更是大同小异。

既然你已经工作了,那么建议先拿接触的最多的即你工作中用的框架的源码看起。除了看代码,还要善于使用xdebug之类的调试工具去跟踪代码执行流程。多看,多运行,才会明白得越来越多

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. 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,
