PHP中的函数在哪里能看到 想研究一下函数的底层实现????
百度了 都没有 只有函数的用法!
------解决思路----------------------
看源码去呀!

那你在哪里下载 php 的?
www.php.net 这是 php 的官网

去官网上下载PHP的源码包,然后配置个Ctags啥的。就可以慢慢看了。
其中一些函数,实际上是宏定义。
而大多数的PHP函数,都是通过PHP_FUNCTION(function_name)这样实现的。
源码目录中, ext目录包含了PHP的大多数扩展的函数定义。例如数组的一些操作是在标准扩展standard中,也就是ext/standard/array.c中实现的,字符串的相关函数是在ext/standard/string.c中实现的。
自己慢慢看吧。

------解决思路----------------------
我觉得既然选择了php语言,就没必要过多研究底层,可能往框架或者网络架构那边发展更合适一些
------解决思路----------------------
如果是一年经验,还是先不要看源码好。先看看框架的实现吧。

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,
