关于php和DAO的问题
摆渡了一下php+dao关键字,好像没有多少这方面资料。在坛子里搜索了一下,结果居然没有。不知道那位实际运用了DAO+php,交流一下经验。
------解决方案--------------------
如果想要用DAO,通常都要用接口抽象化操作。
PHP也是可以办到的,而且,我在实际的开发中也常用。
不过,任何一种模式都不会独立存在于系统之中,
建议,lz可以参考一下J2EE的设计模式。
把它的模型,用PHP实现,大体模块应该就清晰了。
设计模式是不受语言限制的,还是先理解传统OOP语言中的DAO,在把它转到php上的好。

此DAO非彼DAO也
VB里面的DAO(Data Access Objects)是操作数据库的一组函数库,后来被ADO取代(微软发明的类似的缩写词还有ODBC,MDAC等等,也算微软的一大特色)
设计模式里面的DAO(Data Access Object)是OO Design的一种设计策略,用来抽象和封装对数据源的访问

dao==数据岛概念。有点数据仓储的味道~
是数据操作的高度抽象化。
作为,开源的东西,自写类还是不错的。~

DeepSeek cannot convert files directly to PDF. Depending on the file type, you can use different methods: Common documents (Word, Excel, PowerPoint): Use Microsoft Office, LibreOffice and other software to export as PDF. Image: Save as PDF using image viewer or image processing software. Web pages: Use the browser's "Print into PDF" function or the dedicated web page to PDF tool. Uncommon formats: Find the right converter and convert it to PDF. It is crucial to choose the right tools and develop a plan based on the actual situation.

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,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
