Description:
------------

From manual page: http://www.php.net/regexp.reference.back-references
---
(If I'm off-base here, just ignore me)
This page should have the "$n" form of the backreference. "being the preferred one".  See http://php.net/manual/en/function.preg-replace.php

This is not a bug. It seems you are confusing back references within a pattern, with references in a replacement string.

Numeric back references are used within a regex pattern to match what has been matched by an earlier (more left) subpattern. These use the backslash-number syntax only.

Replacement strings can use the backslash-number syntax, or the alternative and preferred dollar-number syntax, to refer to subpatterns from the match, to insert into the replacement.

Thanks. And thanks for being polite.
