我最近从 IIS Express 切换到 Windows Server 上的 IIS。在进行迁移时，我在识别 PHP、ODBC 安装等方面遇到了问题。但是，即使我已经拥有 SSL 证书，我仍收到以下错误。

Array
(
     [0] => Array
         (
             [0] => 08001
             [SQLSTATE] => 08001
             [1] => -2146893019
             [code] => -2146893019
             [2] => [Microsoft][ODBC Driver 18 for SQL Server]SSL

         )

         (

         )

)

我想相信问题出在连接设置上。数据库版本为 Microsoft SQL Server 2019。

"Database", "UID"=>"UID","PWD"=>"PWD");
   $connection = sqlsrv_connect( $serverName, $connectionInfo);

   if( !$connection ) {
     die(print_r( sqlsrv_errors(), true));
   }
