内容中含有 "S 等字符干扰正则的解决办法
我发现内容中含有某些字符文章显示，正则匹配方面就有问题了，比如如下字符：
"s 和 { } 等。
比如discuz的门户文章显示也没有很好的处理这个问题，我发布一篇文章含有 "S 这个字符，发布之后，文章显示空白。初步猜测是这些特殊字符跟正则的某些元字符冲突造成的，请问如何解决这个问题？好像加了转义也不可以呀。
回复讨论(解决方案)
转义下，模式修正符再加个“i”试试？
转义应该就可以了，你的代码是如何写的？

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,
Describe the SOLID principles and how they apply to PHP development.
Apr 03, 2025 am 12:04 AM
The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
