$mydb = new wpdb($DB_USER, $DB_PASSWORD, $DB_NAME, $DB_HOST);
$mydb->show_errors();
In above step you have created a variable called "$mydb". Now with the use of this variable you can access the data of your database specified above in any file.$mydb->show_errors();
Example:-
<?php
global $mydb; // Don't forget to initialize this
$sql="SELECT * FROM customer";
$result = $newdb->get_results($sql);
foreach($result as $cust_record)
{
echo $cust_record->name;

$sql="SELECT * FROM customer";
$result = $newdb->get_results($sql);
foreach($result as $cust_record)
