Introduction
PDO_SQLSRV is a driver that implements the PHP Data Objects (PDO) interface to enable access from PHP to MS SQL Server (starting with SQL Server 2005) and SQL Azure databases.
Installation
The PDO_SQLSRV extension is enabled by adding appropriate DLL file to your PHP extension directory and the corresponding entry to the php.ini file. The PDO_SQLSRV download comes with several driver files. Which driver file you use will depend on 3 factors: the PHP version you are using, whether you are using thread-safe or non-thread-safe PHP, and whether your PHP installation was compiled with the VC6 or VC9 compiler. For example, if you are running PHP 5.3, you are using non-thread-safe PHP, and your PHP installation was compiled with the VC9 compiler, you should use the php_pdo_sqlsrv_53_nts_vc9.dll file. (You should use a non-thread-safe version compiled with the VC9 compiler if you are using IIS as your web server). If you are running PHP 5.2, you are using thread-safe PHP, and your PHP installation was compiled with the VC6 compiler, you should use the php_pdo_sqlsrv_52_ts_vc6.dll file.
For more information about system requirements, see » SQLSRV System Requirements.
The PDO_SQLSRV extension is only compatible with PHP running on Windows. For Linux, see ODBC and » Microsoft's SQL Server ODBC Driver for Linux.
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:
-
Supported operating systems for version 3.0 of the driver include:
-
Windows Server 2008 R2 SP1
Windows Vista SP2
Windows Server 2008 SP2
Windows 7 SP1
-
-
Supported operating systems for version 2.0 of the driver include:
-
Supported operating systems for version 2.0 of the driver include:
-
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.
Microsoft Drivers for PHP for SQL Server, version 3.0 requires PHP 5.3.0 or later. If possible, use PHP 5.3.6, or later. The version 2.0 driver 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.
-
The x86 version of SQL Server Native Client is required on the computer where PHP is running. If you are using a 64-bit operating system, the x86 version of SQL Server Native Client will be installed with the x64 version of SQL Server Native Client (do not install the x86 version of SQL Server Native Client on an x64 operating system).
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.
-
Version 3.0 of the driver requires Microsoft SQL Server 2012 Native Client. You can download Microsoft SQL Server 2012 Native Client from the SQL Server 2012 feature pack page.
-
Version 2.0 of the driver requires Microsoft SQL Server 2008 R2 Native Client. Click on the appropriate link below:
-
This section lists the drivers that are installed for version 2.0 and version 3.0 of the Microsoft Drivers for PHP for SQL Server. PHP version 5.2 is not supported in version 3.0 of the Microsoft Drivers for PHP for SQL Server.
Follow the installation instructions in Loading the Driver to configure the driver for use with the PHP runtime.
Microsoft Drivers 2.0 for PHP for SQL Server installs several versions of the driver:
