Welcome to Webune Support Forums - We provide PHP hosting with MySQL database. Our support and service is unmatched. We are developers like you and we know what PHP developers needs.

Today we are sharing a very useful script written in PHP to test your database connection. This easy and simple to use script will help you confirm the login information you have been given is correct.

For example, lets say you have a script which uses a MySQL database, but you are getting connection errors like:

Access denied for user 'admin'@'localhost' (using password: NO)

This error simply means you don't have the correct database information like your username because the script tried to connect to your database but it was unsuccessful.

UPDATE: After reading some of your replies, there are some of you that are having trouble because no errors show up. If this is true for you, probably your PHP configuration is setup to hide errors, what you can do is add this line at the beginning of our script:

add this line:
ini_set('display_errors', 1);

this will ensure that if you have any errors, it will show up

Please leave your comments, we appreciate your input.
