2012 SQL連接字符串500內部服務器錯誤

Question

我在Windows 2012服務器上使用SQL 2012中的數據庫。我在我的代碼中使用連接字符串連接到它時遇到了一些問題。我已經通過網絡對它進行了測試，並且使用Visual Basic和Excel無任何問題地連接到它。我很難過，因爲我無法連接到它，它與我的代碼有關，我確信它。額外的一雙眼睛會有所幫助。

<?php 
    $database_server = "servername\databaseservername"; 
    $database_port = "1433"; 
    $database_authentication = "SQL Server"; 
    $database_user = "username"; 
    $database_password = "password"; 
    $database_name = "DatabaseName"; 
    $root = $_SERVER["DOCUMENT_ROOT"]; 
?> 

<?php 
require_once("includes/inc_files.php"); 
$current_page = "find"; 
$filter = coalesce($_GET["filter"], "Events"); 
$search = coalesce($_GET["search"], ""); 
$latitude = coalesce($_GET["latitude"], $_SESSION["latitude"], ""); 
$longitude = coalesce($_GET["longitude"], $_SESSION["longitude"], ""); 
if (!empty($latitude) && !isset($_SESSION["latitude"])) $_SESSION["latitude"] = 
$latitude; 
if (!empty($longitude) && !isset($_SESSION["longitude"])) $_SESSION["longitude"] = 
$longitude; 

$query = preg_replace("#[^a-z 0-9?!]#i", "", $search); 
$do_search = false; 
if ($filter == "Events" && !empty($latitude) && !empty($longitude)) { 
$do_search = true; 
$radius = 40; 
$sql_columns = " 
    Events.ID AS eventid, 
    Events.VenueID AS venueid, 
    Events.Title AS title, 
    Events.EventDate AS date, 
    Venues.Name AS venue, 
    Venues.City AS city, 
    ROUND(dbo.GETDISTANCE(Venues.Lat, Venues.Lon, $latitude, $longitude, 'Miles'), 0) AS distance, 
    Venues.ImageName AS photo"; 
$sql_where = " 
    " . (!empty($search) ? "Events.Tags LIKE '%$query%' AND " : "") . "Events.EventDate >= GETDATE() AND CAST(CAST(Events.VenueID AS varchar(10)) AS bigint) IN (
     SELECT ID 
     FROM LiveData 
     WHERE ROUND(dbo.GETDISTANCE(Lat, Lon, $latitude, $longitude, 'Miles'), 0) BETWEEN 0 AND $radius 
    )"; 
$sql = " 
    SELECT $sql_columns 
    FROM LiveData AS Events 
    INNER JOIN LiveData AS Venues ON CAST(CAST(Events.VenueID AS varchar(10)) AS bigint) = Venues.ID 
    WHERE $sql_where"; 
$query_recordsets = $database_mssql->query($sql); 
$query_data = $query_recordsets[0]; 
$page = !empty($_GET["page"]) ? (int) $_GET["page"] : 1; 
$per_page = 20; 
$total_count = count($query_data); 
$pagination = new Pagination($page, $per_page, $total_count); 
$sql = " 
    SELECT * 
    FROM (
     SELECT ROW_NUMBER() OVER(ORDER BY Events.EventDate ASC) AS row, 
       $sql_columns 
     FROM LiveData AS Events 
     INNER JOIN LiveData AS Venues ON CAST(CAST(Events.VenueID AS varchar(10)) AS bigint) = Venues.ID 
     WHERE $sql_where 
    ) AS a 
    WHERE row >= {$pagination->offset()} AND row < {$pagination->offset()} + $per_page"; 
$query_recordsets = $database_mssql->query($sql); 
$query_data = $query_recordsets[0]; 
} 
else if ($filter == "People") { 
$do_search = true; 
$sql = " 
    SELECT username, 
      first_name, 
      last_name, 
      country 
    FROM users 
    WHERE username LIKE '%$query%' OR CONCAT(first_name, ' ', last_name) LIKE '%$query%'"; 
$query_data = User::find_by_sql($sql); 
$page = !empty($_GET["page"]) ? (int) $_GET["page"] : 1; 
$per_page = 20; 
$total_count = count($query_data); 
$pagination = new Pagination($page, $per_page, $total_count); 
$sql .= " LIMIT $per_page OFFSET {$pagination->offset()}"; 
$query_data = User::find_by_sql($sql); 
} 
?> 

我在內部託管所有這些內容並將其推送到網絡上。當我在我的瀏覽器中使用localhost查看它時，我收到500內部服務器錯誤。

任何意見都會很棒！

只是爲此線程添加一個答案，它看起來像IIS和MSSQL 2012安裝不正確。與數據庫端口也有衝突。 MySQL和MSSQL都使用端口1433.
