Welcome,
Some useful guides you should read:
* PHP: Documentation Tools
* PHP: Documentation Tools
All the docs repos can be found in the PHP GitHub ( php.net · GitHub ) and are named 'doc-<language>' - eg. 'doc-en' for English, 'doc-de' for German, etc.
If you know the page you want to make changes to but don't know which file it is in the repo, there's a "Submit a Pull Request" button at the bottom of each documentation page on the website that will take you to the file.
I think the easiest way to get started, if you don't already have any changes you want to propose, is to browse the open issues at Issues · php/doc-en · GitHub and create a pull request for any you think you can resolve.
There's also the pinned tracker issues for version updates, and several other tracker issues:
* Missing classes: Document missing classes · Issue #2162 · php/doc-en · GitHub
* Missing functions: Document missing functions/methods · Issue #2163 · php/doc-en · GitHub
* Interactive examples: Enable More Examples for WASM · Issue #4799 · php/doc-en · GitHub
Do check if something still needs to be done on the trackers (including any pending PRs) before working on changes as the issues are not always kept up-to-date.
If you're able to write in multiple languages, you may be able to help with translations. PHP: Documentation Tools can help you find pages that need updating.
If you have further queries, as well as posting here you can ask on the #php-doc channel on the PHP Community Discord: https://discord.phpc.social - a number of docs contributors hang out there.
