My database shows 0mb

My database show 0mb and 0 tables, although I have created a table. Also, when I try this:

<?php
$servername = "localhost";
$username = "id7644931_btm24";
$password = "sexsexsex";
$database = "id7644931_math";

$conn = new PDO("mysql:host=$servername;dbname=$database", $username, $password);
if(!$con){
  	echo 'Not Connected To Server';
}
?>

It says that id didn’t connect to the server.

The database stats from the panel take time to update just ignore.
