使用融合图表连接数据库（Mysql）

I am running PHP Version 5.5.24, i have also included the "fusionchart.php" in the project folder too. When i googled for solution , the browser shows the "did not match any document"

<?php

   include("fusioncharts.php");



   $hostdb = "localhost";  // MySQl host
   $userdb = "root";  // MySQL username
   $passdb = "suba sah 16";  // MySQL password
   $namedb = "world";  // MySQL database name


      $dbhandle = new mysqli($hostdb, $userdb, $passdb, $namedb,'0','/opt/lampp/var/mysql/mysql.sock');


   if ($dbhandle->connect_error) {
    exit("There was an error with your connection: ".$dbhandle->connect_error);
   }
?>

Error:

When i run the code above , i shows the error as follows.. query($strQuery) or exit("Error code ({$dbhandle->errno}): {$dbhandle->error}"); ?>

Your help will be appreciated. Thanks

I tried to run the above code in my localhost, but couldn't find the error mentioned by you. The code is working error free. If you have missed something, I would like to know what did you missed out.

You can even see whether the database connectivity done is correctly done or not.
