Detect if user is bot or real user.

Install

Usage

Basic Usage

If there is library that fits your needs and implements CloakerInterface - use it.

use Cloakings\CloakingsCommon\CloakerFactory;
use Cloakings\CloakingsCommon\CloakModeEnum;
use Cloakings\CloakingsCommon\SampleCloaker;

$cloaker = new SampleCloaker();
// or
$cloaker = (new CloakerFactory())->create(SampleCloaker::class);

$result = $cloaker->handle(new Request(server: ['HTTP_USER_AGENT' => 'Chrome 100']));
// $result->mode === CloakModeEnum::Real
// show real site

$result = $cloaker->handle(new Request(server: ['HTTP_USER_AGENT' => 'GoogleBot', 'REMOTE_ADDR' => '8.8.8.8']));
// $result->mode === CloakModeEnum::Fake
// show fake site

$result = $cloaker->handle(new Request(server: ['HTTP_USER_AGENT' => 'GoogleBot', 'REMOTE_ADDR' => '11.22.33.44']));
// $result->mode === CloakModeEnum::Response
// stop and show this response

$result = $cloaker->handle(new Request()); // no user agent
// $result->mode === CloakModeEnum::Error
// decide by yourself: may be show default (fake or real) site, may be try chaining decision to another cloaker

Chaining

If you want visitor to pass several cloakers then use ChainCloaker

use Cloakings\CloakingsCommon\AlwaysRealCloaker;
use Cloakings\CloakingsCommon\CloakerFactory;
use Cloakings\CloakingsCommon\SampleCloaker;

$cloaker = (new CloakerFactory())->createChain([
    AlwaysRealCloaker::class,
    SampleCloaker::class,
]);

Logic:

• if cloaker tells "Fake" - stop and return "Fake"
• if cloaker tells "Response" - stop and return "Response"
• if cloaker tells "Real" - continue to the next cloaker; return last "Real" response
• if cloaker tells "Error" - continue to the next cloaker; return last "Real" response; if all cloakers return "Error" then return last "Error"

Create own Cloaker

Implement CloakerInterface.

Return mode:

• "Real": it seems that visitor is real human user
• "Fake": it seems that visitor is bot user
• "Response": don't show fake or real site but this response: usually temp pages for additional checks like captcha or js challenge
• "Error": cannot decide

Return response: used only in mode "Response" or "Error"

Return probability: how sure you are 0.0 - 1.0. Useful if you have several cloakers and one says "Real", another says "Fake" and you want to decide. Usually just keep default 1.0.
