====== Request for Comments ======

This page gives an overview of the current RFCs for PHP.

To create a new RFC, see [[rfc:howto|How To Create an RFC]].

Note: An RFC is effectively "owned" by the person that created it. If you want to make changes, get permission from the creator. If no agreement can be found, the only course of action is to create a competing RFC. In this case the old RFC page should be modified to become an intermediate page that points to all the competing RFC's.

A new page in this RFC namespace will automatically be loaded with an RFC [[rfc:template|template]]. Customize as needed.
