Web Proxy Application built on php-proxy library ready to be installed on your server. Keep in mind that sites/pages that are too script-heavy or with too many “dynamic parts”, may not work with this proxy script. That is a known limitation of web proxies. For such sites, you should use an actual proxy server to route your browser’s HTTP requests through: https://www.proxynova.com/proxy-software/
as a sidenote, the website (https://www.php-proxy.com/) uses google-analytics. But the application seems trade-free. 4/5 because of that.
