首页有十五个sql语句涉及7个数据表，加载速度极慢（大概6秒,2Mb带宽),有什么办法优化吗？
回复讨论(解决方案)
直接拿sql分析 desc select * from tabname …… 关键字段加索引，优化程序写法。
看来是要优化你的SQL了。index，缓存
2mb 6sec 并不能说极慢，只是稍慢
你可以缓存首页查询结果，使数据库查询的影响减到最小
如果效果不明显，则说明是你的页面布局不合理，嵌套太多
建议多多看看相关书籍吧，会有认识的。

首页缓存起来吧，动态数据的话，就用ajax请求。另外建立必要的索引

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AMSelect 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 AMDependency 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.
