我一直以为他可以像MYSQL一个，一个KEY整存多行多行哪样，但实际不行啊，比如存文章只能一个KEY对一个HASH，但现在有一个需求就是，我要知道这个KEY里面的某个字段是否等于某个值，如果等于我就直接取，就像MYSQL的WHERE一样。但好像REDIS没有这样的命令，直接取字段把值拿出来然后在程序里面对比？求大神

回复内容：

redis是纯粹的存储，不是计算，他能做的是提供快速的读写操作，当然心情好也提供一些计算，比如排序

redis是Key-Value结构，属于非关系型数据库，狭义地说，他仅有的查询方式就是根据Key查Value

MySQL是关系型数据库
Where是关系型数据库特有的指令

你需要的是mset……

Dependency 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.

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
