Laravel's collections are awesome!
This project provides a "jsfiddle" style environment to test, run & share collection code.

The playground usespib to evaluate PHP code directly inside the browser.
When you load the playground, Vue downloads a compiled web assembly build of PHP. This is used by they playground tolocally eval your code as you type.

The disadvantages of this approach are the limited browser support - for it to work you need to be running a desktopversion of Chrome or Firefox that is recent. Safari & Edge aren't support at the moment.Seethis issue for more information.

The playground is built as a PWA, which provides several advantages.

• Caching of downloaded PHP binary (no need to re-download the binary on each page load)
• Support for using offline (since the code is eval'd locally, it will work without any internet)

• api contains the lambda function that is used to save playground as github gists, so they can be saved & shared.
• php-app contain a small PHP application that is used to evaluate the collection code, catch errors and return itback to the client as json.
• php-src contains the scripts to build the in web assembly build, containing PHP + thephp-app code.
• playground contains the Vue application which communicates with PHP to run your code, and display the results
