PHP 7 Integration

PHP (using cURL)

<?php
namespace IPHub;

class Lookup {
	public static function isBadIP(string $ip, string $key, bool $strict = false) {
		$ch = curl_init();
		curl_setopt_array($ch, [
			CURLOPT_URL => "http://v2.api.iphub.info/ip/{$ip}",
			CURLOPT_RETURNTRANSFER => true,
			CURLOPT_HTTPHEADER => ["X-Key: {$key}"]
		]);
		try {
			$block = json_decode(curl_exec($ch))->block;
		} catch (Exception $e) {
			throw $e;
		}
		if ($block) {
			if ($strict) {
				return true;
			} elseif (!$strict && $block === 1) {
				return true;
			}
		}
		return false;
	}
}

To query an IP; you save the above php script to a file named iphub.class.php, require it in your application then access the isBadIP method using the Scope Resolution Operator in the IPHub namespace:

<?php
require_once('iphub.class.php');
use IPHub\Lookup as IPHub;

$ip = $_SERVER['REMOTE_ADDR'];

// (string) $ip, (string) $key, (boolean) $strict
if (IPHub::isBadIP($ip, "YOUR_API_KEY_HERE")) {
	die("Request blocked as you appear to be browsing from a VPN/Proxy/Server. Please contact IPHub.info if you believe this is a mistake. Your IP address is $ip.");
}

// Remainder of your page content here

Please note that the code above doesn’t handle exceptions. Use a try/catch statement to avoid throwing errors on your web app:

try {
	$block = IPHub::isBadIP($ip, "YOUR_API_KEY_HERE");
} catch (Exception $e) {
	$block = false;
}
