在正则表达式中仅匹配字母的最佳方法是什么? [英] What is the best way to match only letters in a regex?

问题描述

我真的很想使用\ w，但是它也与下划线匹配，所以我要使用[A-Za-z]，它感觉到不必要的冗长和以美国为中心.有一个更好的方法吗?像[\ w ^ _]之类的东西(我怀疑语法是否正确)?

I would really like to use \w but it also matches underscores so I'm going with [A-Za-z] which feels unnecessarily verbose and America centric. Is there a better way to do this? Something like [\w^_] (I doubt I got that syntax right)?

推荐答案

您也可以使用/[a-z]/i或/[[:alpha:]]/.实际上，\w包含数字，因此甚至无法使用.

You could use /[a-z]/i or /[[:alpha:]]/ just as well. In fact, \w includes numbers so that won't even work.
