哪里可以找到完整的regex引用?

时间:2022-03-19 13:34:15

I came across some regular expressions that I've never seen before, and I can't find any information on what they do. Here's an example:

我遇到了一些我以前从未见过的正则表达式,我找不到它们的任何信息。这里有一个例子:

/[\p{Z}\p{Cc}\p{Cf}\p{Cs}\p{Pi}\p{Pf}]/u

I'm looking for a full reference for regex.

我在寻找regex的完整参考资料。

P.S. I think the example provided only words in certain languages. It works in PHP but not Javascript.

附注:我认为这个例子只提供了某些语言的词汇。它使用PHP而不是Javascript。

What you're looking at are Unicode character properties, also in the PHP docs, as well as the regular expression modifiers for the u at the end of the regex.

您所看到的是Unicode字符属性(也在PHP文档中),以及regex末尾u的正则表达式修饰符。
