让PHP能正常的操作SQL Server，除了上述的PHP扩展，还需要安装 SQL Server Native Client，Version 2.0 需要 Microsoft® SQL Server® 2008 Native Client，Version 3.0 需要 Microsoft® SQL Server® 2012 Native Client。

Version 2.0 相关下载如下：

1、Microsoft® SQL Server® 2008 Native Client

[微软官方]下载：X86版本   X64版本

以 PHP5.3.29 操作SQL Server2008 为例，当前操作系统为 Windows 7 sp1（64位）:

一、软件安装

1、下载安装 X64版本 的 Microsoft® SQL Server® 2012 Native Client。

2、下载 Version 3.0 相关软件。我本地用的是 xampp运行PHP，即 Apache以非fcgi模式运行PHP，故需要选择 “线程安全版”的 php_sqlsrv_53_ts.dll，并拷贝到 PHP的ext目录。

在 php.ini 中配置下扩展：

extension=php_sqlsrv_53_ts.dll

二、操作示例

<?php

$dbHost = "192.168.137.99";

$uid = "blog.snsgou.com";

$pwd = "snsgou08808";

$dbName = 'sg_user';

$charset = 'utf-8';

$connectionInfo = array("UID" => $uid, "PWD" => $pwd, "Database" => $dbName, 'CharacterSet' => $charset);

$conn = sqlsrv_connect($dbHost, $connectionInfo);

if ($conn == false) {

	echo "连接失败！";

	die(print_r(sqlsrv_errors(), true));

}

//++++++++++++++++++++++++++++++++++++++++++++++++++++++++

// 1.查询

$sql = "SELECT TOP 10 * FROM t_user";

$query = sqlsrv_query($conn, $sql);

while ($row = sqlsrv_fetch_array($query)) {

	echo $row['Id'] . "-----" . $row['Email'] . "<br/>";

}

// 2.插入、更新

$sql = "insert into [SnsClass]([year],[month],[day],[className]) values ('2014','02','05', '初三(3)版')";

$query = sqlsrv_query($conn, $sql);

?>
