php - FreeBSD 上 PHP 的 MSSQL 连接

Question

作为我的问题的延伸:Remote connect to SQL Server Standard Edition from PHP/FreeBSD

我正在尝试让我们的 FreeBSD/Apache/PHP 服务器能够查询我们的 WinServer2003/SQL-Server-2000 机器。请注意，这不是针对公共(public)系统，仅针对内部报告功能 - 因此此时性能不是关键。 最初的问题帮助我准备了 MSSQL 服务器以进行连接，现在从它那里得到了某种响应。但是我还没有成功连接到它。

我已经尝试过 PDO_dblib、mssql (FreeTDS) - 还没有尝试过 ODBC。如果我能让 PDO 工作，我会更愿意，所以这就是我的目标 - 它也是我尝试过的两个中最成功的。

我使用 PDO:dblib 的 PHP 脚本

<?php 

ini_set('display_errors', 1); 
ini_set('log_errors', 1); 
ini_set('error_log', dirname(__FILE__) . '/error_log.txt'); 
error_reporting(E_ALL);

$servername = '192.168.1.51';
$port = '1433';
$serverdsn = $servername.':'.$port;
$username = 'webserver';
$password = '123456';
$dbname = 'oneServer_staging';

$sqlstatement = 'SELECT * FROM ordersp';

try 
        {
            $pdo = new PDO ("dblib:host=".$serverdsn.";dbname=".$dbname,$username,$password);
        } 
        catch (PDOException $e)
        {
            echo "Failed to get DB handle: " . $e->getMessage() . "\n";
            exit;
        }
exit; 

此 PDO:dblib 脚本在浏览器中运行时的结果:

Failed to get DB handle: SQLSTATE[28000] Login incorrect. (severity 9)

在 MSSQL 服务器的应用程序日志中，我发现了这个:

在对 FreeTDS 发表评论后进行编辑

我的 PHP 脚本利用 mssql_connect()/FreeTDS

<?php 

ini_set('display_errors', 1); 
ini_set('log_errors', 1); 
ini_set('error_log', dirname(__FILE__) . '/error_log.txt'); 
error_reporting(E_ALL);

$username = 'webserver';
$password = '123456';
$dbname = 'oneServer_staging';

$sqlstatement = 'SELECT * FROM ordersp';

$link = mssql_connect('MYMSDN', $username, $password);

if (!$link) {
    die('Something went wrong while connecting to MSSQL');
}

此 mssql/FreeTDS 脚本在浏览器中运行时的结果:

Warning: mssql_connect(): Unable to connect to server: MYMSDN in

        # Whether to write a TDSDUMP file for diagnostic purposes
        # (setting this to /tmp is insecure on a multi-user system)
        dump file = /tmp/freetds.log
;       debug flags = 0xffff

        # Command and connection timeouts
;       timeout = 10
;       connect timeout = 10

        # If you get out of memory errors, it may mean that your client
        # is trying to allocate a huge buffer for a TEXT field.
        # (Microsoft servers sometimes pretend TEXT columns are
        # 4 GB wide!)   If you have this problem, try setting
        # 'text size' to a more reasonable limit
        text size = 64512

# A typical Microsoft SQL Server 2000 configuration
[MYMSDN]
        host = 192.168.1.51
        port = 1433
        tds version = 8.0
        client charset = UTF-8

文件 /tmp/freetds.log 在执行脚本时没有显示任何内容，但是如果我使用 # tsql -C 命令，它会更新。

下面几行代码行得通吗？

ini_set('display_errors', 1); 
ini_set('log_errors', 1); 
ini_set('error_log', dirname(__FILE__) . '/error_log.txt'); 
error_reporting(E_ALL);

$username = 'webserver';
$password = '123456';
$dbname = 'oneServer_staging';
$servername = '192.168.1.51';

if (!$link = mssql_connect($servername, $username, $password)) {
   exit('Error: Could not make a database connection using ' . $username . '@' . $servername);
}

if (!mssql_select_db($dbname, $link)) {
   exit('Error: Could not connect to database ' . $dbname);
}
?>
