是这个意思但是文件夹images前面的目录也是未知的,不一定是 www.abc/n1/n2 有可能是m1不要闭门造车!不存在这种可能性
img 如果没有真实存在的 url,则图片是不可能显示的,所以图片路径不可能是不确定的
如果你是抓取网页图片,完全可以根据抓取后保存的图片路径自己构造 url,并不需要再原 url 上修改
如果你只是想做个练习,那么请不要把精力放在这个臆想的题目上

这是真实情况,因为某些原因,现在网址是动态的,所以图片录入进去以后,更换动态网址后,图片地址不对应了,所以得仅仅images目录后面的路径,前面的路径是动态的。并且文件夹images后面的目录也是可以动态添加的

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,

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.

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.
