Description:
------------
---
From manual page: https://php.net/function.preg-replace
---

The documentation states: "replacement may contain references of the form \\n or $n"

I think it should be "\n" instead of "\\n", see test-script 

Test script:
---------------
echo(preg_replace('/#.*#/', 'A\0B', '#test#'));


Expected result:
----------------
A\0B

Actual result:
--------------
A#test#B

\\n is because people are liable to use double-quoted strings so the backslash would have to be escaped. Doubled backslashes will work for both types of strings without needing a second thought. But IMO the section there is a bit overzealous on the "you need doubled backslashes" when the truth is that PCRE only wants one, so maybe it could be adjusted a bit.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
