My code is like

        <?php

    require_once 'vendor/autoload.php';

    use Goutte\Client;

    use Symfony\Component\HttpClient\HttpClient;

    //generate random string

    function generateRandomString($length = 10)

    {

        $characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';

        $charactersLength = strlen($characters);

        $randomString = '';

        for ($i = 0; $i < $length; $i++) {

            $randomString .= $characters[rand(0, $charactersLength - 1)];

        }

        return $randomString;

    }

    //creating Goutte Client

    $client = new Client(HttpClient::create(array(

        'headers' => array(

            'Accept' => 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',

            'Accept-Language' => 'en-US,en;q=0.5',

            'Connection' => 'keep-alive',

        ),

    )));

    //Request

    $crawler = $client->request('GET', 'example.com/login');

    $session_id = generateRandomString(15);

    

    //For write php object in the text file...

    $objData = serialize($crawler);

    $filePath = getcwd() . DIRECTORY_SEPARATOR . "sessions" . DIRECTORY_SEPARATOR . "obj" . $session_id . ".txt";

    $fp = fopen($filePath, "w");

    fwrite($fp, $objData);

    fclose($fp);

    

    //To read the text file to get the object

    $crawler_new = file_get_contents(getcwd() . DIRECTORY_SEPARATOR . "sessions" . DIRECTORY_SEPARATOR . "obj" . $session_id . ".txt");

    $obj = unserialize($crawler_new);

    

    print_r($obj);

    die();

above code results below

any one can help me to store the $crawler object in file??
basically want to ask from client to put reCaptcha by human.
I am working on a project in which I want to perform all process through server using Goutte and for this on login page reCaptcha is applied which I want to get fill by client side and then will continue the other process.

My Answer:
use Goutte\Client;

$client = new Client();
$crawler = $client->request('GET', 'http://www.example.com');

// Store $crawler in a session variable
$_SESSION['crawler'] = $crawler;

// Retrieve $crawler from session variable
$crawler = $_SESSION['crawler'];
