我已成功将 Limesurvey.org 应用程序 (LAMP) 部署到 Pivotal Cloud。除了 MySQL 数据库不允许应用程序创建表外，该应用程序大部分都按预期工作。激活给定调查后，应用程序需要创建表格来存储响应。

我已经在本地 (Linux) 上安装了相同的应用程序，我没有任何问题。另一个已将相同应用程序（不同版本）部署到 PCF 的团队建议我使用脚本（如下）来捕获 VCAP_SERVICES 信息以连接数据库。然而，在“cf push”之后，应用程序根本无法工作。这是一个 PHP 脚本。我在 Java 中似乎有类似的代码。

为什么我需要向 PCF 上的数据库提供 VCAP_SERVICES 信息？

也许如果我了解脚本试图做什么，我将能够解决这个问题。

任何信息和/或提示将不胜感激。

        $encrypted_password = base64_decode ( $base64_encrypted_password );
        $decryption_result = openssl_private_decrypt ( $encrypted_password, $decrypted_password, $rsa_private_key );

        }

        return $appConfigurations;

这不是给 db 用户适当的权限的问题吗？
