Paste a snippet, hit run, and 3v4l shows you what it does on dozens of PHP versions side by side. It's handy when your host upgrades PHP and something suddenly stops working.

What you can do with it

  • Test a quick idea without setting up a server
  • Check if code breaks on a newer PHP version
  • Share a link to a snippet when asking for help
