Run PHP in WASM?

[Lewiscowles1986]

Hello 👋

With the rise of projects such as WordPress playground, and php-wasm. Do you think it might make more sense to run PHP on the client, to save server costs?

I Logged into Exercism today to find out if this was the model pivoted to, and found you're still apparently using Docker and an older PHP version.

Why I think this is a good idea. Using caching headers, service-workers and a WASM-ified PHP, with a little work, a lot could be saved, and other types of exercise could be made possible.

PHP.net is using something similar as an example of live-docs

I made my own toy of this wanting multiple runtime versions, which I intend to use in my own notes for evergreen miro-labs

uses

https://github.com/Lewiscowles1986/php-wasm-builder based from Derick Rethans own https://github.com/derickr/php-wasm-builder (which I believe is used for PHP.net)

Challenges I foresee:

• Decide if single static artifact or multiple artifact / request
• Integrating PHPUnit
• Saving and loading user code
• re-writing / adding experiment flags to make all of this safe
