I don't understand your question. Emacs' regexps facilities are
explained in the manual, (info "(emacs)Regexps") . You will find on that
page a link to further details for programmers. I don't know what new
non-standard ops perl and php and ruby have, but if they aren't in the
Emacs manual, then they most probably aren't in Emacs.

It sounds like you're trying to use a manual for one group of
applications to learn another application. No question, that must be
quite a bear. Probably easier to use the manual for Emacs to learn
Emacs.
