 **Welcome to the Microsoft Drivers for PHP for Microsoft SQL Server**
 
-The Microsoft Drivers for PHP for Microsoft SQL Server are PHP extensions that allow for the reading and writing of SQL Server data from within PHP scripts. The SQLSRV extension provides a procedural interface while the PDO_SQLSRV extension implements PHP Data Objects (PDO) for accessing data in all editions of SQL Server 2008 and later (including Azure SQL DB). These drivers rely on the Microsoft ODBC Driver for SQL Server to handle the low-level communication with SQL Server.

 This release contains the SQLSRV and PDO_SQLSRV drivers for PHP 7.* with improvements on both drivers and some limitations (see Limitations below for details).  Upcoming releases will contain additional functionality, bug fixes, and more (see Plans below for more details).

 ## Building and Installing the Drivers on Windows
 
 The drivers are distributed as pre-compiled extensions for PHP found on the [releases page](https://github.com/Microsoft/msphpsql/releases). They are available in thread-safe and non thread-safe versions, and in 32-bit and 64-bit versions. The source code for the drivers is also available, and you can compile them as thread safe or non-thread safe versions. The thread safety configuration of your web server will determine which version you need. 
  
-If you choose to build the drivers, you must be able to build PHP 7 without including these extensions. For help building PHP on Windows, see the [official PHP website][phpbuild]. For details on compiling the drivers, see the [documentation](https://github.com/Microsoft/msphpsql/tree/dev/buildscripts#windows) -- a buildscript is provided, but you can also compile the drivers manually.

-To load the drivers, make sure that the driver is in your PHP extension directory and enable it in your PHP installation's php.ini file by adding `extension=php_sqlsrv.dll` and/or `extension=php_pdo_sqlsrv.dll` to it.  If necessary, specify the extension directory using `extension_dir`, for example: `extension_dir = "C:\PHP\ext"`. Note that the precompiled binaries have different names -- substitute accordingly in php.ini. for more details on loading the drivers, see [Loading the PHP SQL Driver](https://docs.microsoft.com/en-us/sql/connect/php/loading-the-php-sql-driver) on MSDN.
