The LINK and UNLINK methods are draft status, subject to change and/or not being accepted as a specification at all.

https://tools.ietf.org/html/draft-snell-link-method-11

I don't think it is a good idea to introduce verbs that may not ever be accepted or widely used into the test server.

I fully agree. Therefore I'm suspending this request.

Guys, don't we need to move forward?

LINK/UNLINK is a draft but I can attest that many people already use it. The usage drives everything & BTW it's just a debate about an HTTP verb, nothing more!

In fact, php is using nodejs http-parser https://github.com/nodejs/http-parser code.

And guess what... nodejs http-parser code has adopted LINK/UNLINK support since few months!
https://github.com/nodejs/http-parser/commit/e557b62744e4f487a303b25b27c56947d7a8bacc

Maybe it's time to backport that in php source?

I can make the pull request and everything needed to have this pull request merged. Furthermore it could be backported to every actively supported php version.

> LINK/UNLINK is a draft […]

The latest respective draft which I could find is "HTTP Link and
Unlink Methods|draft-snell-link-method-12"[1], which has been
expired on March 24, 2016. Can you point to a more recent RFC?

> The usage drives everything & BTW it's just a debate about an

If it is nothing more, we should consider to accept *all*
potentially allowable verbs. That would also simplify the parser.
