PDO sqlsrv：找不到驱动程序

Question

我尝试用PHP连接到SQL Server。在我的本地机器上使用XAMPP，一切运行良好。但现在我要将我的应用程序带到生产服务器上。

在此服务器上安装了Microsoft IIS 6.1并运行PHP版本7.0.7。我还从here安装了ODBC驱动程序。接下来，我将php.ini文件中的以下行取消注释：

extension=php_sqlsrv_7_nts.dll
extension=php_pdo_sqlsrv_7_nts.dll

我从official microsoft site获得了文件。

我的问题是什么？

不幸的是，在我重新启动IIS之后。 PDO函数抛出PDOException错误，并显示以下消息：

could not find driver

对于连接我正在使用以下功能，该功能在我的本地机器上运行良好：

try {
    $con = new PDO("sqlsrv:Server=" . SERVER . ";Database=" . DATABASE, USERNAME, PASSWORD);
    // set the PDO error mode to exception
    $con->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
    echo "No connection: " . $e->getMessage();
    exit;
}

我还能做什么？

Answer 1

在Windows Server上找到错误日志后，我自己解决了错误。

我的日志中出现此错误：

[21-Apr-2017 07:12:14 UTC] PHP Warning:  PHP Startup: Unable to load dynamic library '...\ext\php_pdo_sqlsrv_7_nts.dll' - %1 is not a valid Win32 application. in Unknown on line 0

然后我再次下载了driver并安装了x64-Driver。最后它没有任何问题。

Answer 2

我花了一些时间解决“无人驾驶”错误。我经历了这里提到的一些步骤，发现了一些新的错误后对我有帮助的步骤。供将来参考：

• 从Microsoft下载最新的驱动程序（如Julian Schmuckli所说）。
• 使用Phpinfo()检查XAMPP是否为64位（！）。如果您使用的是32位，则需要其他驱动程序。
• 将驱动程序添加到Php.ini文件中，并将dll的文件保存在php / ext-folder中（saber tabatabaee yazdi的问题）。
• 对于连接，请使用以下代码：

$dbh = new PDO ("sqlsrv:Server=$server;Database=$dbname",$username,$pw); 

如果添加端口，请使用：

$server = "192.168.1.15, 51022";

其中IP（可以是主机名）是您的服务器，而51022是您的端口。

1. 从此链接-https://docs.microsoft.com/en-us/sql/connect/php/download-drivers-php-sql-server?view=sql-server-ver15

   下载并提取PHP Version - 7.4文件

2. 将文件粘贴到.dll中，您的路径可能会不同。

在C:\xampp\php\ext中

3. 在底部或扩展部分中添加这两行。

   php.ini

4. 重新启动Xampp服务器，我建议重新启动计算机，然后一切都会正常运行。

检查是否启用了SqlSRV

使用 extension=php_sqlsrv_74_ts_x64.dll extension=php_pdo_sqlsrv_74_ts_x64.dll 或http：//localhost/dashboard/phpinfo.php像这样检查-

希望，它将对某人有所帮助。
