This is the ad hoc tutorial on how to enable PHP PDO for MSSQL. First, we will download and install necessary files and packages. Then we will make the needed system configurations. Finally, we will install the pdo_sqlrv package, create the PHP configuration file and test the connection with PDO to MSSQL server.
