Building PHP extensions with WebAssembly
Session en Anglais - Intermédiaire
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.
PHP, 150x Faster still Legacy Friendly
Session en Anglais - Intermédiaire
Your PHP scripts are constantly waiting for the database, HTTP requests, or files. Solutions exist, but often require rewriting code.
In this talk, I will show you how to push PHP to its limits running scripts 150x faster. The ingredients: FrankenPHP threads, Swow coroutines, PHP Generators, a sprinkle of PHP, and a dash of Go to orchestrate it all. This approach works for any PHP code both legacy and new, including blocking I/O.
