$starting_url = 'http://yahoo.com';
$options = [
    'type' => 'main', // $type is optional.(Default: main),
    'url_deletion' => true  // Default: true
];
$result = \SearchBot::request($starting_url, $options);

if($result->exists()) {

    // Symfony\Component\BrowserKit\Response
    // See http://api.symfony.com/2.3/Symfony/Component/BrowserKit/Response.html
    $response = $result->response();

    // Symfony\Component\DomCrawler/Crawler
    // See http://api.symfony.com/2.3/Symfony/Component/DomCrawler/Crawler.html
    $crawler = $result->crawler();

    $result->links(function($url, $text){

        // All links including URL & text will come here.

    });

    $result->queues(function($crawler_queue, $url, $text){

        // All links that do not exist in DB will come here.
        // $crawler_queue has already type and url.
        $crawler_queue->save();

    });

} else {
