我不得不将 Paypal Payment pro 集成到客户的网站上。我首先在我的服务器上安装 paypal php SDK。它在 php 5.2.17 上运行，似乎运行良好。
当我完成测试时，我将 SDK 从我的服务器移动到运行 php 5.3.2 的客户端服务器，但由于某种原因它不起作用。
一开始我们确定这是权限问题，因为脚本无法写入 paypal.log 文件
大约一个星期以来，我们正在与托管公司合作解决问题。一个想法是将服务器回滚到 5.2.17（以匹配我服务器的 php 版本）。此更改解决了问题，但是服务器上的其他网站被搞砸了，这迫使我们回到 5.3.2
我一直在寻找解决方案。我在这里找到的一个解决方案： PHP 5.3.1 上的 PayPal 错误消息 与梨包有关。
任何人都知道是否需要任何特殊的梨包才能使 SDK 工作？
以下是一些技术信息：
当错误报告设置为 -1 时尝试 doDirectPayment 示例时出现以下错误

和 5 个软管中的 2 个：

我知道这是一个非常具体的问题，熟悉这个问题的人的可能性很低，但我不得不问。
