Link Guardian

A simple PHP script for traffic filtering and redirection. Its primary purpose is to protect a webpage/website from bots using pre-defined filters.

Block incoming requests based on:

• Country IP
• Hostname
• Useragent
• Browser
• OS

A request that matches the filters will be redirected to the URL or page specified in the config.php file.

Usage

1. Edit the configuration file config.php and adjust your settings. For accurate results, set the API key for ipinfo.io.

2. In your PHP webpage, include the script blackhole.php (see example.php).

<?php
require_once('blackhole.php');

# Check if the request is allowed
$is_allowed = blackhole();

# Log the request information
log_visit($is_allowed);


# Decide what to do with the request
if(!$is_allowed)
{
	redirect();
	exit;
}




# If request passes the filters defined in config.php
$base_url = 'https://www.example.org';


$path = $_SERVER['REQUEST_URI'];

$u = $base_url . $path;


header("Location: $u");
exit;
