php如何输出表格内容比较快捷高效。

比如我现在有test表。
里面有id,fenlei,mc
分别代表,id,自动增长,
fenlei,参赛地区
mc,具体的评选参数
id     fenlei    mc
1       北京      卫生好
2       上海      卫生好
3       上海      服务好
4       天津      卫生好
5       天津      服务好

csv

啥意思,我是要在线输出,

这些都是最基础的统计
善用数组的交并差、array_count_values、array_sum、count 组合一下就是了

我是新手,还请领导给一个示例,感谢了。。

你先给个数组,我懒得打字

完全新手入门,还请领导多多指教。

这叫数组啊?

这叫数组啊?

我不知道这个不叫数组,问题是我给了你数组,到时候我怎么生成数组呢。。。
所以,我想看到你把生成数字的过程,我刚刚给的书数据表的记录。

我刚刚给的是数据表的记录,不是数组,问题我怎么通过这个表来生成数组,我也不是很清楚。。
还请领导动动手,感谢。

在线等领导的好代码。感谢。。

select a.fenlei, count(*), count(*)/(select count(*) from test)*100 as percentage, constitutefrom test a, (select fenlei, group_concat(mc,',',cnt) as constitute from(select fenlei, mc, count(*) as cnt from test group by 1,2) t group by 1) t1where a.fenlei=t1.fenlei group by 1

执行该 SQL 指令,可得到这样的数据
Array(    [0] => Array        (            [fenlei] => 北京            [count(*)] => 2            [percentage] => 25.0000            [constitute] => 服务好,1,卫生好,1        )    [1] => Array        (            [fenlei] => 上海            [count(*)] => 4            [percentage] => 50.0000            [constitute] => 服务好,2,卫生好,2        )    [2] => Array        (            [fenlei] => 天津            [count(*)] => 2            [percentage] => 25.0000            [constitute] => 服务好,1,卫生好,1        ))
Copy after login
输出时需对 constitute 列做一下处理

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.
