$SetExpressCheckoutRequestDetails = new stdClass();
$SetExpressCheckoutRequestDetails->SetExpressCheckoutRequestDetails = new
SoapVar( $args1,
SOAP_ENC_OBJECT,
'SetExpressCheckoutRequestDetailsType',
'urn:ebay:api:PayPalAPI'
);
//var_dump($SetExpressCheckoutRequestDetails);
//die();
$params = new SoapVar( $SetExpressCheckoutRequestDetails, SOAP_ENC_OBJECT,
'SetExpressCheckoutRequestDetails' );
$result = $client->SetExpressCheckout( $params );
var_dump($result);
die();
