The SQLSRV extension can be used on the following operating systems:
- Windows Vista Service Pack 2 or later
- Windows Server 2008 Service Pack 2 or later
- Windows Server 2008 R2
- Windows 7
The SQLSRV extension requires that the Microsoft SQL Server 2012 Native
Client be installed on the same computer that is running PHP. If the Microsoft
SQL Server 2012 Native Client is not already installed, click the appropriate link below
to download it:
The SQLSRV download comes 8 driver files, four of which are for PDO support.
If you are running non-thread-safe PHP (PHP 5.3), use the php_sqlsrv_53_nts.dll
file. (You should use a non-thread-safe version if you are using IIS as your
web server). If you are running thread-safe PHP, use the php_sqlsrv_53_ts.dll
file. Similarly for PHP 5.4, use the php_sqlsrv_54_nts.dll or php_sqlsrv_54_ts.dll
depending on whether your PHP installation is non-thread-safe or thread-safe.
The most recent version of the driver is available for download here:
» SQLSRV 4.0 download. If you need support
for PHP 5.2 and/or PHP compiled with VC6, use the 2.0 release of the driver:
» SQLSRV 2.0 download.
