Passing multiple certificates through Curl request using Guzzle

Question

I have an http request that uses a key, certificate, and certificate chain. How can it be translated to Guzzle? The problem is that I do not know how to add all my certificates to the Guzzle request. In the documentation there is an example for only one certificate

Example of my request:

// curl -vvv -X POST --header 'Content-Type: application/x-www-form-urlencoded' --header 'Accept: application/json' --cacert client-bundle.pem --key key.pem --cert cert.pem 'my_url'

My function is sending a request using Guzzle at the moment:

try {
$response = $this->request('POST', 'my_url', [
                'headers' => [
                    'Content-Type' => 'application/x-www-form-urlencoded',
                    'Accept' => 'application/json'
                ],

            ]);

return Json::decode($response->getBody()->getContents());
            $this->checkResponse($result);

        } catch (GuzzleException $e) {
            return $e->getMessage();
}

I tried to find an example of sending a request with the transfer of several certificates. I could not find such an example, using only one certificate does not suit me

To add multiple certificates to a Guzzle request, you can use the ssl_key and cert options in the request options array. The ssl_key option can be set to the path of your private key file, and the cert option can be set to the path of your certificate file.

$certFile = 'cert.pem';
$keyFile = 'key.pem';
$caFile = 'client-bundle.pem';

$client = new GuzzleHttp\Client();

try {
    $response = $client->request('POST', 'my_url', [
        'headers' => [
            'Content-Type' => 'application/x-www-form-urlencoded',
            'Accept' => 'application/json'
        ],
        'cert' => [$certFile, $keyFile],
        'ssl_key' => $keyFile,
        'verify' => $caFile
    ]);

    $result = $response->getBody()->getContents();

    $this->checkResponse($result);

    return Json::decode($result);

} catch (GuzzleHttp\Exception\GuzzleException $e) {
    return $e->getMessage();
}
