It will be the other way round, it should be mysqli
The regular mysql extension was removed from PHP 7, so 7.0+ only has the mysqli extension. Even on PHP 5.6, the mysqli extension would typically be installed.
If the config currently has mysqli and it's still not working then you'll need to contact your host, but it sounds like you must be on an incredibly old version of PHP if that's the case.
