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

Note: An RFC page is effectively “owned” by the person that created it. If you want to add changes, get permission by 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 will 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 a template for an RFC. Customize as needed.
