我试图在Windows Server 2012 R2 VM上安装php应用程序（TestRail），并且在使用SQL驱动程序时遇到了一些麻烦。我开始从光盘安装SQL Server 2012并尝试从Web平台安装程序安装PHP，尽管在IIS中针对SQL Server的PHP v5.6的Microsoft Drivers 3.2下载仍然失败，并指出缺少依赖项是罪魁祸首。浏览日志，我看到了：

看起来依赖是ODBC驱动程序11，由于签名验证而无法安装，因此我决定手动抓取所有内容。我得到了3.2 php驱动程序并将它们放在ext目录中并在php.ini中注册了所有这些，但当我尝试运行msodbcsql.msi包时，我遇到了Web平台安装程序的问题，我一直收到错误安装失败，因为我的操作系统不支持它。但是，Microsoft网站上的下载页面将Server 2012列为兼容，当我运行sqlsrv_errors（）时，我得到：
[message] => This extension requires the Microsoft ODBC Driver 11 for SQL Server. Access the following URL to download the ODBC Driver 11 for SQL Server for x86: http://go.microsoft.com/fwlink/?LinkId=163712 )
和
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified [message] => [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified ) )
所以它看起来仍然在寻找那个ODBC驱动程序，但是当我尝试从错误消息中指定的链接下载它时，它告诉我它与我的操作系统不兼容，当我尝试使用WPI失败的签名验证。这里我唯一看到的其他帖子建议抓取x64版本而不是x86版本，但这不是页面上的选项，Web平台安装程序甚至会尝试安装不兼容的驱动程序似乎很奇怪。如何安装此驱动程序？
