System Requirements for the Microsoft Drivers for PHP for SQL Server

DownloadDownload PHP Driver

This article lists the components that must be installed on your system to access data in a SQL Server or Azure SQL Database using the Microsoft Drivers for PHP for SQL Server.

Versions 3.2 and later of the Microsoft PHP Drivers for SQL Server are officially supported. For full details on support lifecycles and requirements of the PHP drivers, see the support matrix.

PHP

For information about how to download and install the latest stable PHP binaries, see the PHP web site. The Microsoft Drivers for PHP for SQL Server require the right versions of PHP as detailed in PHP Version support.

ODBC Driver

The correct version of the Microsoft ODBC Driver for SQL Server is required on the computer on which PHP is running. You can download all supported versions of the driver for supported platforms on this page.

If you are downloading the Windows version of the driver on a 64-bit version of Windows, the ODBC 64-bit installer installs both 32-bit and 64-bit ODBC drivers. If you use a 32-bit version of Windows, use the ODBC x86 installer. On non-Windows platforms, only 64-bit versions of the driver are available.

PHP for SQL Server driver version →

5.8 5.6 5.3 5.2 4.3 4.0 3.2
ODBC Driver 17+ Y Y Y Y
ODBC Driver 13.1 Y Y Y Y Y Y
ODBC Driver 13 Y
ODBC Driver 11 Y Y Y Y Y Y Y

If you are using the SQLSRV driver, sqlsrv_client_info returns information about which version of SQL Server Microsoft ODBC Driver for SQL Server 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.

For information about using PHP with Azure SQL Database, see Connecting to Microsoft Azure SQL Database.

Driver Versions

This section lists the driver files that are included with each version of the Microsoft Drivers for PHP for SQL Server. Each installation package contains SQLSRV and PDO_SQLSRV driver files in threaded and non-threaded variants. On Windows, they are also available in 32-bit and 64-bit variants. To configure the driver for use with the PHP runtime, follow the installation instructions in Loading the Microsoft Drivers for PHP for SQL Server.

On supported versions of Linux and macOS, the appropriate drivers can be installed using PHP's PECL package system, following the Linux and macOS installation instructions. Alternatively, you can download prebuilt binaries for your platform from the Microsoft Drivers for PHP for SQL Server GitHub project page -- the tables below list the files found in the prebuilt binary packages.
