Fetch data from an Array or directly from the xml-rpc query

Hello good morning I made a connection with a WebService with PHP through the xml-rpc library and brought some data. Now I am trying to fetch only the i_account and connect_time fields from the array or directly from the query but it is not working for me either way.

I share and hope you can support me.

<?php

include 'lib/xmlrpc/xmlrpc.inc';

    $params = array(new xmlrpcval(array(
            "i_account"          => new xmlrpcval("2893", "int"),
            "start_date"          => new xmlrpcval("00:00:00.000 GMT Mon Mar 09 2020", "string"),
            "end_date"          => new xmlrpcval("23:59:59.000 GMT Mon Mar 09 2020", "string"),
            "limit"          => new xmlrpcval("1", "int"),


    ), 'struct'));

    $msg = new xmlrpcmsg('getAccountCDRs', $params);

    /* replace here URL  and credentials to access to the API */
    $cli = new xmlrpc_client('https://sip.serv.net.mx/xmlapi/xmlapi');
    $cli->setSSLVerifyPeer(false);
    $cli->setSSLVerifyHost(false);
    $cli->setCredentials('ABACOM', 'contraseña', CURLAUTH_DIGEST);

    $r = $cli->send($msg);       /* 20 seconds timeout */

    if ($r->faultCode()) {
      error_log("Fault. Code: " . $r->faultCode() . ", Reason: " . $r->faultString());
      return false;
    }

    print_r($r);

?>
