无法在WordPress中打开数据库

Question

我在Wordpress中创建了一个新数据库，但我无法访问它：

PHP代码：

$connect = mysqli_connect($dbhost, $dbuser, $dbpass) or die("Unable to Connect     to '$dbhost'");
mysqli_select_db($dbname) or die("Could not open the db '$dbname'");

我收到了“无法打开数据库”消息。我做错了什么？

试试这个

 $conn = mysqli_connect($dbhost, $dbuser, $dbpass , $dbname) or die("Unable to Connect to database" );

$sql="SELECT * FROM  yourtablename";

if ($result=mysqli_query($conn,$sql))
  {

  while ($row=mysqli_fetch_row($result))
    {
    echo $row[0];
    echo $row[1];

    }

  mysqli_free_result($result);
}

mysqli_close($con);
?>
