我需要使用 PHP 连接到远程 MSSQL 服务器。我已经使用 dblib 成功连接，但它有一些非常“讨厌”的限制。

我发现它无法获取 ntext 格式的列行，有一个简单的解决方法，但它限制了输出（通过查询将 ntext 转换为 nvarchar），然后我注意到它也有获取行的问题以十进制格式（或者看起来，不幸的是，为所有内容抛出的一般错误 4004 并不是很有帮助）。

我喜欢需要太多的黑客攻击，有没有更好的方法来解决这个问题，也许我应该研究一个不同的数据库库来寻找我的连接？

值得注意的是，我使用 mssql_* 取得了巨大成功，但这显然不是一个理想的方法，我希望继续使用 PDO。

值得注意的事情；

我在 Debian 上运行，我知道微软已经发布了 ODBC 驱动程序，但是他们的驱动程序下载有问题，因此不起作用（至少在非 RHEL 系统上似乎没有）

不要使用dblib/mssql:驱动程序。

如果您在 Windows 上，请使用sqlsrv:驱动程序。（您必须下载一些 DLL——链接的说明。）

如果您使用的是 unix，请使用PDOodbc:驱动程序，最好使用 unixODBC 风格。在 Debian 和 Ubuntu 上，您可以通过简单的apt-get install php5-odbc.

当我执行时：

TDSDUMPCONFIG=stdout TDSDUMP=stdout tsql -S <name in TDS.conf> -U '<domain>\<username>' -p 1443 -P <password>

我明白了：
