Note, to those that wonder: It moved to git.php.net as github only contains a mirror. And other parts of the PHP project are still in transition. There's also a mercurial mirror. The PHP source module is named php-src.

While that is true they now encourages people to submit patches as github pull requests: https://wiki.php.net/vcs/gitworkflow

Thanks for the clarification. It's been mirrored on github for a long time, but it's almost always a pretty old release.

To OP, "hosted on git" and "hosted on github" are two very different things.
