 **PHP Monitor** (or *phpmon*) is a lightweight macOS utility app that runs on your Mac and displays the active PHP version in your status bar. It's tightly integrated with [Laravel Valet](https://github.com/laravel/valet), so <u>you need to have it set up if you want to use all of the functionality of the app</u> (consult the FAQ below with info about how to set up your environment).
