System Requirements (Microsoft Drivers for PHP for SQL Server)

To access data in a SQL Server 2005 or later database using the Microsoft Drivers for PHP for SQL Server, you must have the following components installed on your computer:

  • A supported operating system, such as:

    • Windows Server 2003 Service Pack 1

    • Windows XP Service Pack 3

    • Windows Vista Service Pack 1 or later

    • Windows Server 2008

    • Windows Server 2008 R2

    • Windows 7

  • PHP 5. For information about how to download and install the latest stable binaries, visit http://php.net.

    The Microsoft Drivers for PHP for SQL Server works with PHP 5.2.4 or later. If possible, use PHP 5.2.13, or later.

  • A version of the driver file must be in your PHP extension directory. See Driver Versions later in this topic for information about the different driver files. See Loading the Microsoft Drivers for PHP for SQL Server for information on configuring the driver for the PHP runtime.

    (See The Data Center for the Microsoft Drivers for PHP for SQL Server for information on where to download the Microsoft Drivers for PHP for SQL Server.)

  • A Web server. Your Web server must be configured to run PHP. For information about hosting PHP applications with Internet Information Services (IIS) 6.0, see Using FastCGI to Host PHP Applications on IIS 6.0. For information about hosting PHP applications with IIS 7.0, see Using FastCGI to Host PHP Applications on IIS 7.0.

    The Microsoft Drivers for PHP for SQL Server has been tested using IIS 6 and IIS 7 with FastCGI.

  • Microsoft SQL Server 2008 R2 Native Client installed on the same computer on which PHP is running.

    If you are using the SQLSRV driver, sqlsrv_client_info will return information about which version of SQL Server Native Client is being used by the Microsoft Drivers for PHP for SQL Server. If you are using the PDO_SQLSRV driver, you can use PDO::getAttribute to discover the version.

  • Microsoft SQL Server 2008 R2 Native Client is required to use Microsoft Drivers for PHP for SQL Server. (The x86 version of SQL Server Native Client will be installed with the X64 version of SQL Server Native Client.) To download and install SQL Server 2008 R2 Native Client now, click on the appropriate link below:

    Download the X86 package

    Download the X64 package
