Answer 1

You would need to make 2 different connections

Now when you use the $mysqliDB1->.... you are talking to the DB1 database and when you use the $mysqliDB2->.... you are talking to the DB2 database

So

$client = $mysqliDB1->query("SELECT client FROM appointments WHERE ID = $results")
         ->fetch_object();

$locn = $mysqliDB2->query("SELECT state,zipcode 
                           FROM location 
                           WHERE ClientID = {$client->FirstName}")
                  ->fetch_object();
echo $locn->state;
echo $locn->zipcode;

I am guessing the table name and so on, but I am not clarevoyant so you will have to fill that in for yourself.
