alt Hacker NewsOr FrankenPHP, or hell, there's still even good old Apache. Or avoid the SAPI interface entirely with servers in PHP like Workerman, AMPHP, or Swoole.

Those are great solutions for production deployment, but to the previous commenter's point, for iterating on your local machine during development work, nothing beats just running `php -S`.
Launch the interpreter's built-in dev server in your project directory, load up localhost in your browser, work on your code, and testing incremental changes locally is just a matter of hitting F5.
