Example

require('vendor/autoload.php');

use Proxy\Http\Request;
use Proxy\Proxy;

$request = Request::createFromGlobals();

$proxy = new Proxy();

$proxy->getEventDispatcher()->addListener('request.before_send', function($event){

    $event['request']->headers->set('X-Forwarded-For', 'php-proxy');

});

$proxy->getEventDispatcher()->addListener('request.sent', function($event){

    if($event['response']->getStatusCode() != 200){
        die("Bad status code!");
    }

});

$proxy->getEventDispatcher()->addListener('request.complete', function($event){

    $content = $event['response']->getContent();
    $content .= '<!-- via php-proxy -->';

    $event['response']->setContent($content);

});

$response = $proxy->forward($request, "http://www.yahoo.com");

// send the response back to the client
$response->send();

Plugin Example

namespace Proxy\Plugin;

use Proxy\Plugin\AbstractPlugin;
use Proxy\Event\ProxyEvent;

use Proxy\Html;

class MultiSiteMatchPlugin extends AbstractPlugin {

    // Matches multiple domain names (abc.com, abc.de, abc.pl) using regex (you MUST use / character)
    protected $url_pattern = '/^abc\.(com|de|pl)$/is';
    // Matches a single domain name
    //protected $url_pattern = 'abc.com';

    public function onCompleted(ProxyEvent $event){

        $response = $event['response'];

        $html = $response->getContent();

        // do your stuff here...

        $response->setContent($html);
    }
}

Notice that you must use the / character for regexes on $url_pattern
