我已經下載了PayPal API (SOAP) for PHP。PHP：「無法重新聲明課程...」，即使我更改了課程名稱
我得到這個錯誤：
Fatal error: Cannot redeclare class SOAP_Client in /home/me/app1/plugins/mbpPlatformFrontendPlugin/lib/paypal/PayPal/SOAP/Client.php on line 83
奇怪的是：如果我改變類來還有什麼有史以來名稱，例如SOAP_Client_foo，我得到
Fatal error: Cannot redeclare class SOAP_Client_foo in /home/me/app1/plugins/mbpPlatformFrontendPlugin/lib/paypal/PayPal/SOAP/Client.php on line 83
有什麼想法？

編輯：
我已經輸入...paypal$ grep -R 'Client.php' *，並且我得到這樣的：
PayPal/CallerServices.php://require_once 'PayPal/SOAP/Client.php';
PayPal/SOAP/Client.php:// $Id: Client.php,v 1.1.1.1 2006/02/19
PayPal/SOAP/WSDL.php: //require_once 'PayPal/SOAP/Client.php
這是肯定的，有我的應用程序沒有更多的文件，其中可能包括客戶端.PHP。
