JMS串行器錯誤：當不在對象中時使用$ this

Question

我正在處理付款處理頁面。我們正在使用Authorize.net來處理交易。我導入了Authorize的php庫及其所有依賴項。

當我嘗試處理交易測試，我得到以下錯誤：

Fatal error: Using $this when not in object context in /home/ticketstroyfair/public_html/include/authorize/vendor/jms/serializer/src/JMS/Serializer/Serializer.php on line 99 

起初我還以爲這東西在我的代碼，所以我試圖運行授權的PHP樣本交易，並得到同樣的錯誤。

該串行器昨天剛剛從GitHub下載。 https://github.com/schmittjoh/serializer

這裏是授權示例代碼：

<?php 
require 'include/authorize/autoload.php'; 
use net\authorize\api\contract\v1 as AnetAPI; 
use net\authorize\api\controller as AnetController; 

define("AUTHORIZENET_LOG_FILE","phplog"); 

// Common setup for API credentials 
    $merchantAuthentication = new AnetAPI\MerchantAuthenticationType(); 
    $merchantAuthentication->setName("YOU_API_LOGIN_ID"); 
    $merchantAuthentication->setTransactionKey("YOUR_TRANSACTION_KEY"); 
    $refId = 'ref' . time(); 

// Create the payment data for a credit card 
    $creditCard = new AnetAPI\CreditCardType(); 
    $creditCard->setCardNumber("4111111111111111"); 
    $creditCard->setExpirationDate("2038-12"); 
    $paymentOne = new AnetAPI\PaymentType(); 
    $paymentOne->setCreditCard($creditCard); 

// Create a transaction 
    $transactionRequestType = new AnetAPI\TransactionRequestType(); 
    $transactionRequestType->setTransactionType("authCaptureTransaction"); 
    $transactionRequestType->setAmount(151.51); 
    $transactionRequestType->setPayment($paymentOne); 
    $request = new AnetAPI\CreateTransactionRequest(); 
    $request->setMerchantAuthentication($merchantAuthentication); 
    $request->setRefId($refId); 
    $request->setTransactionRequest($transactionRequestType); 
    $controller = new AnetController\CreateTransactionController($request); 
    $response = $controller->executeWithApiResponse(\net\authorize\api\constants\ANetEnvironment::SANDBOX); 

if ($response != null) 
{ 
    $tresponse = $response->getTransactionResponse(); 
    if (($tresponse != null) && ($tresponse->getResponseCode()=="1")) 
    { 
    echo "Charge Credit Card AUTH CODE : " . $tresponse->getAuthCode() . "\n"; 
    echo "Charge Credit Card TRANS ID : " . $tresponse->getTransId() . "\n"; 
    } 
    else 
    { 
    echo "Charge Credit Card ERROR : Invalid response\n"; 
    } 
} 
else 
{ 
    echo "Charge Credit Card Null response returned"; 
} 
?> 

是什麼原因造成的錯誤任何想法？

我敢打賭，你使用的PHP版本比5.4.0老，對不對？

在該版本下不支持在匿名函數中調用$ this。 見Using $this in anonymous function

這裏http://php.net/manual/en/functions.anonymous.php

如果我是正確的，我高度建議至少更新到PHP 5.6.x

希望我能幫助一下。
