PHP Regex: How to match \r and \n without using [\r\n]?

Question

I have tested \\v (vertical white space) for matching \\r\\n and their combinations, but I found out that \\v does not match \\r

Answer 1

This doesn't answer the question for alternatives, because \v works perfectly well

\v matches any character considered vertical whitespace; this includes the platform's carriage return and line feed characters (newline) plus several other characters, all listed in the table below.

• "#\\v+#" escape the backslash

or

• '#\v+#' use single quotes

In both cases, you will get a match for any combination of \r and \n.
