Question

我尝试使用PHP建立与SQL服务器的连接

我可以使用SQL Server Management studio远程访问服务器。

然后如果我跑：

select @@servername + '\' + @@servicename

我明白了：

Server_Name\Instance_Name

（也许值得注意的是我无法使用此Server_Name连接到Management Studio中的服务器 - 我必须使用公共IP，不知道为什么，但我是noob所以也许那是正常的吗？）

我正在运行的PHP脚本（在我用来建立Management Studio Connection的同一台机器上）如下所示：

<?php

$username = "same_user_as_for_management_studio";

$password = "same_pass_as_for_management_studio";

$serverName = "Server_Name\Instance_Name";

$db = "Example";


$connectionInfo = array( "Database"=> $db, "UID"=>$username, "PWD"=>$password);
$conn = sqlsrv_connect( $serverName, $connectionInfo);

if( $conn ) {
     echo "Connection established.<br />";
}else{
     echo "Connection could not be established.<br />";
     die( print_r( sqlsrv_errors(), true));
}
?>

我曾尝试将服务器名称替换为公共IP，但仍然没有乐趣。我得到的错误是：

Array ( [0] => Array ( [0] => 08001 [SQLSTATE] => 08001 [1] => 87 [code] => 87 [2] => [Microsoft][SQL Server Native Client 11.0]SQL Server Network Interfaces: Connection string is not valid [87].

SQL服务器是否在默认端口上运行？

$serverName = "serverName\sqlexpress, 1542"; //serverName\instanceName, portNumber (default is 1433)
