我正在使用paypal rest API,但是我收到了一个错误.这是我的代码:

function makePaymentUsingPayPal($total, $currency, $paymentDesc, $returnUrl, $cancelUrl) {

    // set billing address
    $addr = new Address();
    $addr->setLine1('fh52 N Main ST');
    $addr->setCity('Johnstownfhf');
    $addr->setCountry_code('UK');
    $addr->setPostal_code('35345');
    $addr->setState('DF');

    $card->setExpire_year('2015');
    $card->setCvv2('123');
    $card->setFirst_name('dgdg');

    $amountDetails = new Details();
    $amountDetails->setSubtotal('57.41');
    $amountDetails->setTax('0.06');
    $amountDetails->setShipping('0.06');

    $amount = new Amount();
    $amount->setCurrency('USD');
    $amount->setTotal('5.47');
    $amount->setDetails($amountDetails);
