 # PHP Monitor

 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 also gives you quick access to various useful functionality (like switching PHP versions, restarting services, accessing configuration files, and more).

 For me, it comes in handy when running multiple versions of PHP with Homebrew. If you wish to be able to see at a glance which version is currently linked & active with Laravel Valet, PHP Monitor is your new best friend.
