为啥php开源社区不为php开发一个编译器
为什么php开源社区不为php开发一个编译器？
asp.net、jsp都已经可以编译成字节码文件了。这样一来他们执行的速度都得以大幅提升。我一直搞不清楚，除了动态语言本生的因素以外，为什么不开发一个编译器，让php解释器直接解释字节码呢？这可以减少运行时编译的开销，真搞不懂。大家来讨论一下。希望畅所欲言。顺便散分。

gOOGLE搜索 hhvm ，由Facebook打造。这个应该能够满足你的要求。

楼主不必多虑。第一你的想法，php早已经实现了，只不过你不知道罢了。
第二，php运行速度比你讲的jsp,asp.net要快。我做过实验的。你不信可以提出一个问题，用三者实现，然后看结果。php是其它的2倍以上速度。
php语言的独特机制，优化比你想想的要好。
jsp你学过是编译性语言。其实只有php这种脚本语言速度的1/2。是不是让你大跌眼睛？
如果你不相信我的话。可以测试下。

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,
