// After Step 1
$apiContext = new \PayPal\Rest\ApiContext(
    new \PayPal\Auth\OAuthTokenCredential(
        'AYSq3RDGsmBLJE-otTkBtM-jBRd1TCQwFf9RGfwddNXWz0uFU9ztymylOhRS',     // ClientID
        'EGnHDxD_qRPdaLdZz8iCr8N7_MzF-YHPTkjs6NKYQvQSBngp4PTTVWkPZRbL'      // ClientSecret
    )
);

// After Step 2
$creditCard = new \PayPal\Api\CreditCard();
$creditCard->setType("visa")
    ->setNumber("4417119669820331")
    ->setExpireMonth("11")
    ->setExpireYear("2019")
    ->setCvv2("012")
    ->setFirstName("Joe")
    ->setLastName("Shopper");

// After Step 3
try {
    $creditCard->create($apiContext);
    echo $creditCard;
}
catch (\PayPal\Exception\PayPalConnectionException $ex) {
    // This will print the detailed information on the exception. 
    //REALLY HELPFUL FOR DEBUGGING
    echo $ex->getData();
}

//运行php -f paypalDemo.php，　或在apache打开运行
