Building PHP extensions with WebAssembly
What if PHP extensions could be written not just in C, but in almost any programming language, safely, securely, and without steep learning curves?
With WebAssembly and FrankenPHP, this is possible. Wasm lets you create PHP extensions using Rust, Go, or JS, running untrusted code securely in a sandbox. This talk shows how you can build multi-language Wasm plugins for PHP with minimal code and run them with FrankenPHP.
