That might point you in the right direction. Could be GoDaddy doesn’t have your mysql config’ed properly.
Also, you could save this bit of code to a test file called test.php (or whatever you want to call it, so long as it has the .php extension).
<?php phpinfo(); ?>
This will show you php configuration on your webhost. If you don’t see anything for mysql, your hosting probably is not set up to where php and mysql can “talk to each other”
