無法進行連線到SQL Server 2008 Express數據庫

Question

我試圖讓到Microsoft SQL Server 2008 Express的數據庫的連接，我收到以下錯誤：

Connection could not be established. Array ([0] => Array ([0] => IMSSP [SQLSTATE] => IMSSP [1] => -1 [code] => -1 [2] => Invalid option YSHSDB was passed to sqlsrv_connect. [message] => Invalid option YSHSDB was passed to sqlsrv_connect.))

我下面這個http://php.net/manual/en/function.sqlsrv-connect.php

PHP代碼：

<?php 
    $serverName = "SERV002\SQLEXPRESS"; //serverName\instanceName 
    array("Database" => "YSHDB", "UID" => "sa", "PWD" => "myPassword"); 
    $conn = sqlsrv_connect($serverName, $connectionInfo); 

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

編輯：
我得到f ixed線現在我得到這個：「連接不能建立。

我已經檢查，以查看服務器是否允許遠程連接，它

Answer 1

你以錯誤的順序鍵/值對。

PHP的關聯數組語法是：

array(key => value) 

所以，你的代碼應該是：

array("Database" => "YSHDB", "UID" => "sa", "PWD" => "myPassword"); 

我也注意使用sa帳戶連接到SQL Server是一般不好的做法，而不是使用Windows身份驗證（在IIS中使用應用程序池標識或當前身份驗證方案的用戶）或至少一個具有授予的最小權限集的每個應用程序自定義SQL Server登錄用戶帳戶。

至於一篇社論：SQL Server 2008現在已經過時了7年（就像在2005年運行Windows NT 4一樣），請考慮升級，尤其是出於安全原因。

Answer 2

在我的情況下，問題是例如名稱。如果使用默認實例名稱，則不需要設置實例name.Just設置服務器name.This是我的代碼：

<?php 
$serverName = "serverName"; 
$options = array( "UID" => "sa", "PWD" => "mypassword", "Database" => "DBname"); 
$conn = sqlsrv_connect($serverName, $options); 

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