$_SERVER['PATH_INFO] variable failing due to mod_rewrite

问题

I'm currently trying to set up a little routing system but when I rewrite my public/index.php to just public/ my $_SERVER['PATH_INFO] variable fails to get any input.

It works fine without the .htaccess file when I visit:

public/index.php/hello

I get:

Welcome! This is the main page.

But when I rewrite to remove index.php and only leave public/ I am dead in the water.

Does anybody know a fix for this or can someone give me an explanation for it?

Simple routing script that echoes content based on the url data that trails the script

   <?php

    // First, let's define our list of routes.
    // We could put this in a different file and include it in order to separate
    // logic and configuration.
    $routes = array(
        '/'      => 'Welcome! This is the main page.',
        '/hello' => 'Hello, World!',
        '/users' => 'Users!'
    );

    // This is our router.
    function router($routes)
    {
        // Iterate through a given list of routes.
        foreach ($routes as $path => $content) {
            if ($path == $_SERVER['PATH_INFO']) {
                // If the path matches, display its contents and stop the router.
                echo $content;
                return;
            }
        }

        // This can only be reached if none of the routes matched the path.
        echo 'Sorry! Page not found';
    }

    // Execute the router with our list of routes.
    router($routes);

    ?>

My .HTACCESS file

RewriteEngine On

RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /(.*)index\.php($|\ |\?)
RewriteRule ^ /%1 [R=301,L]

Update #1

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

You don't have a rule that tells requests like /public/hello to be routed to the index.php file. Apache and PATH INFO isn't smart enough to figure that out. You need to explicitly tell apache that you want a request routed to a script:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^public/(.*)$ /public/index.php/$1 [L]
