php xml和json数据产生接口

调用方法getData()传入不同的参数可分别生成xml数据或json格式数据
getData($data, '', 'json'); //返回json数据
{"result":"success","msg":"","info":{"data_info":[{"goods_id":"1","last_modify":"1423937979"},{"goods_id":"2","last_modify":"1425595831"},{"goods_id":"3","last_modify":"1423937959"},{"goods_id":"4","last_modify":"1423942862"}],"counts":"4"}}
getData($data, '', 'xml'); //返回xml数据

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.
