Php With Simple Dbo

I need a php file that will take the arguments ‘action, param1, param2, param3’ from ‘file.php?action=action&param1=var_1…’ and call the function action(param1, param2, param3);

this should also include a simple DBO (mysql) that i can config with user,pass, db, and table and make queries like dbo->query(‘SOME sql HERE’);

bids 10 and under will be considered

thank you,
