Escape Regex Newline

Question

How do I make a match \ n in a regex? I want the actual two ASCII values ​​92 and 110 to be matched (as a string).

I am using preg from PHP Thanks

Answer 1

You can either escape the first slash: \\n

Or wrap the first slash in []: [\]n

Answer 2

if you do not want to match the real string, but a string (with two characters), such as '\n' , you just need to avoid the backslash with another \\n so that it is not recognized as linebreak.

But most programming languages ​​are slightly different when it comes to escaping, so you need to check your language documents for this, but maybe two backslashes will work.
