php -S 0.0.0.0:8080 index.php

Deploy

Edit index.php and upload index.php and .htaccess (for apache) to root directory to host a reverse proxy for one site
or put index.php to any directory to host a proxy api (should edit .htaccess)

Nginx config example

Ignore this if you use apache.

location / {
        if (!-e $request_filename) {
            rewrite  ^/(\w+)/(.*)$  /$1/index.php/$2  last;
        }
}

Apache config example

Ignore this if you use .htaccess in this repo.

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^/(\w+)/(.*)$ /$1/index.php/$2 [L,E=PATH_INFO:$2]
</IfModule>
