README

Adjust the environment of a web app behind Cloudflare protection.

Basically if CloudflareEnvAdjuster detects that the remote address in the current request is from one of Cloudflare's ranges, it transparently replaces $_SERVER["REMOTE_ADDR"] with $_SERVER["HTTP_X_FORWARDED_FOR"] and stores the original REMOTE_ADDR into $_SERVER["X_CF_REMOTE_ADDR"].

Usage in an ATK14 application

<?php
// file: config/after_initialize.php
CloudflareEnvAdjuster::AdjustEnv();

Usage in a non-ATK14 application

Place the call to CloudflareEnvAdjuster::AdjustEnv() as close to the beginning of your PHP script as you can.

Installation

Just use the Composer:

composer require atk14/cloudflare-env-adjuster
