Database connection + queries class

Hello, I want to build a class that handles the database connection and the queries. When I have a select query( select name, surname from users where 1 ) for example, I bind the results to let's say $bind1 and $bind2 and while the statement fetches I print the result. My question is how should I return the results outside the class, because there could be more than two binded variables. Probaby the design I'm thinking of isn't very good and should be started from zero.
