【问题描述】：
我有一个 db.php 文件 & 和 init.php 可以在我的 register.php 文件中使用。
我在 MS SQL Server 中有一个数据库，并尝试使用 PDO 连接到它。
这个错误正在显示，我不明白为什么。我使用相同的代码连接到 MySQL 数据库，这插入了记录，但写入 MSSQLServer 时没有
致命错误：未捕获的异常 'PDOException' 带有消息 'could not 在 C:\ooplr\classes\DB.php:14 中找到驱动程序' 堆栈跟踪：#0 C:\ooplr\classes\DB.php(14): PDO->__construct('mssql:host=myserver;...', 'username', 'pwd') #1 C:\ooplr\classes\DB.php(23): DB->__construct() #2 C:\ooplr\classes\Validate.php(8): DB::getInstance() #3 C:\ooplr\register.php(9): Validate->__construct() #4 {main} 抛出 C:\ooplr\classes\DB.php 第 14 行

我怎样才能让它连接和发送数据？

PDO没有mssql的驱动程序。 please see the manual on how to install it. -
谢谢，我已经成功连接了 :-) 我正在查看我现在遇到的哈希问题！
