I built PVM (PHP Version Manager) because switching PHP versions on Windows has always been a clunky, manual process. Most tools are either Linux/macOS-focused or too heavy for quick, developer-friendly usage. I wanted something lightweight, fast, and native to Windows — no WSL, no complicated setups, just a simple PowerShell tool that works out of the box. What’s new and unique is that PVM doesn’t just switch PHP versions — it also manages extensions, php.ini settings, and paths in a way that feels tailored for Windows developers. You can install, enable/disable extensions, and tweak php.ini without digging into folders or restarting services. It’s also designed to be easy to extend, so anyone can add their own commands. I’m most proud that this launch is completely self-contained and dependency-free — no installers, no background services. Just drop it in, and you’re managing multiple PHP versions in minutes. It’s fast, it’s developer-focused, and it finally gives Windows PHP devs the smooth workflow they’ve been missing.
