安装

The SQLSRV extension is enabled by adding appropriate DLL file to your PHP extension directory and the corresponding entry to the php.ini file. 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.

For more information about SQLSRV requirements, see » SQLSRV System Requirements.

The SQLSRV extension is only compatible with PHP 5 running on Windows. Since version 4.0 the SQLSRV extension is compatilbe only with PHP 7.0 running on Linux or Windows.

PHP Warning:  PHP Startup: Unable to load dynamic library '...\ext\php_sqlsrv_56_nts.dll' - %1 is not a valid Win32 application.

This error may occur if the Visual C++ runtime required by sqlsrv can not be found. In this case, "Visual C++ Redistributable for Visual Studio 2012 Update 4 (x86)" had to be installed for the x86 compiled PHP running on a x64 OS. For further investigations, have a look at Sysinternals Process Monitor.

SQLSRV doesn't use mssql_connect - it is it's own extension, therefore to connect you'd use sqlsrv_connect:
