A patch adding the PHP library according to this planned structure is in review here. We'll need the standard PHP, JS, and Java jobs to run for the projects in their respective subdirectories, and we'll need to figure something out for Swift.
- Can the existing CI jobs handle this repo structure, or will modifications be needed?
- Can Wikimedia CI support iOS library testing, which may require proprietary Apple SDKs? (TODO: Investigate if https://github.com/apple/swift-corelibs-xctest will meet our needs.)
