array_column和foreach，性能明智哪个更好？ [英] array_column and foreach, performance wise which is better?

问题描述

与常规的foreach循环相比，我对php函数array_column的性能感到好奇。
在我的情况下，我想从数据库表中获取单列数据到数组中。我的查询结果大约有1万到5万条记录，所以我应该在这里使用常规的foreach循环还是array_column更好？

I am curious about performance of php function array_column as compared to regular foreach loop. In my case I want to get single column data from db table into array. My query results ~10k to ~50k records, so should I go with regular foreach loop or array_column is better here?

推荐答案

array_column 是一个内置函数，可能最快。因此，我的测试还显示 array_column 比foreach循环快％50。

Since array_column is a built-in function, it would probably be fastest one. Hence my tests also showed array_column is %50 faster than a foreach loop.
