Anybody who programs in PHP can be a contributing member of the community that develops and deploys it; the task of deploying PHP, documentation and associated websites is a never ending one. With every release, or release candidate comes a wave of work, which takes a lot of organization and co-ordination.
PHP welcomes pull requests to add tests, fix bugs and to implement RFCs. Please be sure to include tests as appropriate!
If you are fixing a bug, then please submit your PR against the lowest branch
of PHP that the bug affects, or the oldest fully supported version (the first
green branch on
the supported version page. For
example, at the time of writing in mid-2015, this is PHP 5.5, which corresponds
to the PHP-5.5 branch in Git. Please also make sure you add a link to the PR
in the bug on the bug tracker.
Pull requests to implement RFCs should be submitted against master.
Bugs can be filed on the PHP bug tracker. If this is the first time you've filed a bug, we suggest reading the guide to reporting a bug.
Where possible, please include a self-contained reproduction case!
Feature requests are generally submitted in the form of Requests for Comment, ideally accompanied by pull requests. You can find the extremely large list of RFCs that have been previously considered on the PHP Wiki.
You may want to read The Mysterious PHP RFC Process for additional notes on the best way to approach submitting an RFC.
We love getting new tests! PHP is a huge project and improving code coverage is a huge win for every PHP user.
Our QA site includes a page detailing how to write test cases. Please note that the section on submitting pull requests is outdated: in addition to the process listed there, you can also submit pull requests.
There are two ways to contribute to the PHP manual. You can edit the manual and send patches anonymously via the online editor, or you can check the XML source out from Subversion and edit that and build it per the instructions on the documentation site. Patches created that way should be sent to the documentation mailing list.
If you are having trouble contributing to PHP, or just want to talk to a human about what you're working on, you can contact us via the internals mailing list, or the documentation mailing list for documentation issues.
Although not a formal channel, you can also find a number of core developers on the #php.pecl channel on EFnet. Similarly, many documentation writers can be found on #php.doc.
