Answer 1

Please set the root path to include.

<?php include('db.php'); ?> 

Your issue may be resolved.

Answer 2

If the issue is only on server , the following might help you:

1. Check mysqli is enabled on server or not.
2. Recheck username, password and dbname.
3. Check if your db contains a table named user_info if so check column names also.
4. Try debugging using echo 123;exit; , and find where the code breaks..
5. Also check error log file.

Hope this helps you.
