No action is performed after PayPal Adaptive Payment

I was trying this (Method) for Paypal adaptive payments first part goes well but after completing second part nothing happening and no error to view. I know this is already posted but I view all other answers but all in vain. I tried to look other option to do this functionality but it mostly available on "Ruby" or other frameworks but I need it in PHP

Here is the PHP code

class PaypalTest{
public $app_id = "APP-80W284485P519543T";
public $apiUrl = 'https://svcs.sandbox.paypal.com/AdaptivePayments/';
public $paypalUrl="https://www.paypal.com/webscr?cmd=_ap-payment&paykey=";
public $headers;

function __construct(){
    $this->headers = array(
        "X-PAYPAL-SECURITY-USERID: ".$this->api_user,
        "X-PAYPAL-SECURITY-PASSWORD: ".$this->api_pass,
        "X-PAYPAL-SECURITY-SIGNATURE: ".$this->api_sig,
        "X-PAYPAL-REQUEST-DATA-FORMAT: JSON",
        "X-PAYPAL-RESPONSE-DATA-FORMAT: JSON",
        "X-PAYPAL-APPLICATION-ID: ".$this->app_id,
    );

    $this->envelope = array(
        "errorLanguage" => "en_US",
        "detailLevel" => "ReturnAll"
    );
}

function getPaymentOptions($paykey){
    $packet = array(
        "requestEnvelope" => $this->envelope,
        "paykey" => $paykey
    );

    return $this->_paypalSend($packet,"getPaymentOptions");
}
function setPaymentOptions(){

}
function _paypalSend($data,$call){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $this->apiUrl.$call);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
    curl_setopt($ch, CURLOPT_HTTPHEADER, $this->headers);
    $response = json_decode(curl_exec($ch),true);
    return $response;

}
function splitPay(){

// create the pay request
    $createPacket = array(
        "actionType" =>"PAY",
        "currencyCode" => "USD",
        "receiverList" => array(

    $response = $this->_paypalSend($createPacket,"Pay");
    print_r($response);

$payment = new PaypalTest();
$payment->splitPay();

Adaptive Payments is no longer supported for new integrations and should not be used.

Instead, switch to a supported integration such as PayPal Checkout.

(There is also the more specialized PayPal Commerce Platform, available only to approved PayPal Partners.)
