请教关于PHP中关联多表相关字段,并做分页处理的SQL语句写法
我有四个表,分别是tb_bookinfo。tb_booktype。tb_bookcase。tb_publishing。在这几个表中有相互关联的字段,下面是我没有加分页的SQL语句,在do....while()中输出正常。问题是数据越来越大,现在想添加分页功能。代码一直未能改成功,请各位PHP达人帮我看看(不要网上复制过来的分页代码,请根据我的这个SQL语句,改动一下,让我能够实现分页)附分页要求“共N条记录,每页显示N条,当前第N页,第一页,上一页,下一页,尾页”。小弟在此先谢过了。
$query=mysql_query("select b.*,c.name as bookcasename,p.pubname,t.typename from tb_bookinfo b left join tb_bookcase c on b.bookcase=c.id join tb_publishing p on b.ISBN=p.ISBN join tb_booktype t on b.typeid=t.id");

------解决方案--------------------
加上 limit 参数不就可以实现分页了

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. 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. 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.
