无法建立连接到SQL Server（PHP）

连接我可以远程使用SQL Server Management Studio中访问该服务器。

然后，如果我运行：

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

我得到：

Server_Name\Instance_Name

（也许这是值得注意的是，我不能使用此服务器名称来连接到Management Studio中的服务器 - 我有使用公共IP，不知道为什么，但我是noob，所以也许这是正常的？）

我正在运行的PHP脚本（在我用于建立管理Studio连接的同一台机器上）外观像这样：

<?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)); 
} 
?>

我试着用服务器名称代替公有IP，但仍然没有喜悦。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].

语法错误在这里'$ password =“same_pass_as_for_management_studio”';'一件事。它抛出了语法突出显示。 –

@ Fred-ii-发生这种情况时，我为了发布而更改了变量名称，并且没有出现在实际代码中，但是谢谢 –

您的意思恰恰与“无法建立连接”有关吗？你有什么错误信息吗？ – Paolo

SQL服务器是否在默认端口上运行？

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