As is mentioned by the Laravel News site and announced on the GitHub blog, repositories that have PHP have a new feature - introspection showing what methods and functions have changed in pull requests.
The file finder makes it easy to review pull requests and understand how changes impact your code. Now PHP developers can navigate to changed methods and functions right in their pull requests, too.
Searching the file finder for the term function or the name of a changed function in a PHP file will provide you with a filtered view of the results, so you can easily identify and view the most impactful parts of a pull request. Check out the documentation to learn more.
An animation in the post shows the feature at work, making use of the "Jump to" menu to show a drop-down listing of all files changed and the methods changed inside them. These can then be used to jump to parts of the pull request (rather than having to search through the entire thing for changes).
