如何在字符串中独立于它们各自的位置匹配两个值 [英] How to match two values independently of their respectiv postions in a string

问题描述

我正在寻找同时匹配两个值的最佳方法.

I'm searching for the best way to match two values simultaneously.

如果两个值都在一个字符串中，我想得到一个真值，但我不知道它们在字符串中的出现顺序(例如 abcdef 或 bedfa 以防我想匹配 a 和 b)

I'd like to get a true value if both values are in a string but i don't know in which order they appear in the string (e.g. abcdef or bedfa in case i want to match a and b)

是否有比以下更好的解决方案(特别是如果以后我需要更复杂的值来匹配):

Is there a better solution (especially if later I would need more complex values to match) than:

$string =~ m/(a.*b)|(b.*a)/i

推荐答案

$string =~ /a/i && $string =~ /b/i;
