HomeBackend DevelopmentPHP Tutorial进来帮帮忙忙,数据库查询有关问题

各位高手们进来帮帮忙忙,数据库查询问题
有一表存着客户的信息,相对这些地方我们设定了特定的顺序,按着这些顺序罗列出来
这个表的信息如:小李 上海
  小张 陕西西安
  小杨 武汉洪山区
  小黄 北京
  小金 新疆
  小黄 河南郑州
  小周 西藏
我们设定的优先级是 北京,上海,武汉 ,西安,新疆 对没有排序的随便跟在后面就好。
结果是:
小黄 北京
小李 上海
小杨 武汉洪山区
小张 陕西西安
小金 新疆
小黄 河南郑州
小周 西藏
有一个“按地域进行排名”的按钮。点击此按钮的时候将表中的数据按照上面的结果罗列出来。注意模糊查询哦。

------解决方案--------------------
最快捷的方法是单独查你优先级的数据。接下来再查非优先级的数据。两个组合一起就ok了
------解决方案--------------------
1、你需要设有排序键字段,排序时按此字段排序
2、如果你需要的排序顺序与民政部的行政区划代码一致,可直接使用这样可直接排序到县区

------解决方案--------------------
添加新列,按地区指定数值,比如北京001,上海002,,随便的直接100000,然后按这列值排序。

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
