[PHP] Pterocos - Free browser-based PHP editor (no install, no signup)

Hi PHP community,

I built Pterocos (https://pterocos.eu.org) - a free online editor that runs
PHP code entirely in your browser via WebAssembly. No installation, no
account required.

**What Pterocos supports:**
- PHP 🐘
- C# (.NET)
- Rust 🦀
- Python 🐍
- Ruby 💎
- SQL (SQLite and DuckDB)
- Lua
- HTML/CSS/JS

**Why PHP developers might find this useful:**
- Quickly test PHP snippets without XAMPP/MAMP
- Prototype algorithms when away from your main machine
- Share runnable examples in documentation or with learners
- Perfect for beginners who haven't installed PHP yet

The editor runs entirely client-side - your code never leaves your browser.

**Try it:** https://pterocos.eu.org

Would love feedback from the community!
