有什么方法可以把一堆数据打乱排效率较好?
网站的首页

我想取出最新50条，然后打乱排序，因为PHP取出50条
在前台只显示15条
SMARTY设了每15分钟更新一次

这样某程度上就像15分钟就更新数据一次了

SQL方面我已单纯只是 order by `time` desc

想在PHP/SMARTY下手脚

section 找了很久很久都没有乱排序的方案

那只能用PHP数组的处理?

我该如何打乱?

SQL数据是用$stmt->fetchAll(PDO::FETCH_ASSOC); 找出来的

所以是二位数组

------解决思路----------------------
先select出来，然后shuffle
------解决思路----------------------
{$row_v[list].title}
你不是按固定顺序输出第二维的吗？

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.
