为什么这两个PDO类不同（我怎样才能使它们相同）？

我有一个基于Web的PHP电子邮件客户端（ Roundcube ），我安装在UNIX服务器上，马上就产生了这个错误：

Fatal error: Undefined class constant 'MYSQL_ATTR_FOUND_ROWS' in /path/to/file.php on line 134

这是这行代码：

 $result[PDO::MYSQL_ATTR_FOUND_ROWS] = true; 

本地在我的Windows安装它工作正常，所以我比较这两个PDO类：

• Apache不启动：语法错误… DocumentRoot必须是一个目录
• 如何自动replaceApache中的文件？
• Apache Centos 6.5只加载第一个虚拟主机
• Apache 2.2最终使用所有内存（worker mpm）
• 在apache / centosnetworking服务器上redirect页面的最佳方法

 <?php ReflectionClass::export('PDO'); 

活的UNIX服务器上不存在MYSQL_ATTR_FOUND_ROWS属性和其他一些属性。 我通过对未知值进行硬编码做了一个快速修补，并且效果很好，但是我不能确定没有更多的错误（我们也不想使用被黑客入侵的版本）。

PDO类是绝对加载的，我们实际上需要启用它，以便首先安装带有MySQL / PDO选项的Roundcube。 似乎现场服务器的PDO类需要更新，我猜？ 我没有直接控制现场服务器，但我可以给那些做的人的指示。 任何人都可以帮我弄清楚必须做什么？

为了将这些缺失的属性放到活动服务器的PDO库中，我们需要做的最低要求是什么？ 事实上，这里甚至发生了什么，他们为什么如此不同呢？
