“找不到驱动程序”错误。 如何在IIS 7中使用SQL Server配置PHP？

I have a PHP website using SQL Server as the database. I want to put it on the windows server. The server using IIS 7. I have a problem to run my website, when I try to login I always get an error :

PDOException in Connector.php line 55: could not find driver

I did put the pdo sql driver in my php ext. and I already registered that in php.ini but I still got that error.

And in my phpinfo() I could not find the "sqlsrv" words at all. Do you know why and how to fix this?

If you are using IIS for PHP, you should load dlls with nts (non-thread safe) version.

php_sqlsrv_56_nts.dll
php_pdo_sqlsrv_56_nts.dll
