PHP 5.4 and later have a built-in web server these days.

You simply run the command from the terminal:

cd path/to/your/app
php -S 127.0.0.1:8000

Then in your browser go to http://127.0.0.1:8000 and boom, your system should be up and running. (There must be an index.php or index.html file for this to work.)

You could also add a simple Router

<?php
// router.php
if (preg_match('/\.(?:png|jpg|jpeg|gif)_SERVER["REQUEST_URI"])) {
    return false;    // serve the requested resource as-is.
} else { 
    require_once('resolver.php');
}
?>

And then run the command

php -S 127.0.0.1:8000 router.php
