PHP连接sqlserver2008，怎么连接指定ip地址上的数据库

$serverName = "(local)"; //数据库服务器地址$uid = "sa"; //数据库用户名$pwd = "password123"; //数据库密码$connectionInfo = array("UID"=>$uid, "PWD"=>$pwd, "Database"=>"test");$conn = sqlsrv_connect( $serverName, $connectionInfo);if( $conn == false){    echo "连接失败！";    die( print_r( sqlsrv_errors(), true));}if($conn){echo "连接成功";}

连接成功了，但是怎么把local改成127.0.0.1这样的

回复讨论(解决方案)

直接换成ip地址

$serverName = "ip地址";
或
$serverName = "计算机名";
如果服务器上有多个实例，还需要有实例名

远程连接还需开启远程连接服务
由于 sqlserver 2000 的默认远程连接，导致了 SQL攻击 的盛行。
所以现在都学乖了，不经繁琐的远程连接授权，是无法连接的

header("Content-type: text/html; charset=gb2312");$serverName = "127.0.0.1/MSSQLSERVER"; //数据库服务器地址$uid = "sa"; //数据库用户名$pwd = "password123"; //数据库密码$connectionInfo = array("UID"=>$uid, "PWD"=>$pwd, "Database"=>"test");$conn = sqlsrv_connect( $serverName, $connectionInfo);//$conn= new PDO("sqlsrv:Server=127.0.0.1;Database=test","sa","yyyy1111") or die ("PDO Connection faild.");if( $conn == false){    echo "连接失败！";    die( print_r( sqlsrv_errors(), true));}if($conn){echo "连接成功";}

结果：
连接失败！Array ( [0] => Array ( [0] => 08001 [SQLSTATE] => 08001 [1] => 67 [code] => 67 [2] => [Microsoft][SQL Server Native Client 11.0]Named Pipes Provider: Could not open a connection to SQL Server [67].

1、运行 SQL Server 配置管理器：SQL Server Configuration Manager，打开协议 Protocols
      允许命名管道 "named pipes" 和 "tcp/ip"
2、 右键点击 "tcp/ip"，打开属性 Properties 标签 "IP addresses"
3、 在 TCP 动态端口 "TCP Dynamic Ports" 填入 1433
4、 重启 SQL Server

服务器实例这样写：
$serverName = "127.0.01\sqlexpress, 1542"；1542可以不写，默认是1433；

谢谢两位大哥
