how to to change value every looop : How to loop and change everytime value

example run for loop 7 times for inserting day names to database

    for ($t = 0 ; $t < 7 $t++){
        $defaultValues = "INSERT INTO workingDays (bussinessID, day, workingHours) VALUES (?,?,?)";
        $pdo->prepare($defaultValues)->execute([$bussinessID, $dayNames, $hours]);
    }

So it inserts to database like this:

Default values:

>BussinessID: 1, Day: Monday, workingHours: 8

>BussinessID: 1, Day: Tuesday, workingHours: 8

>BussinessID: 1, Day: Wednesday, workingHours: 8

>BussinessID: 1, Day: Thursday, workingHours: 8

>BussinessID: 1, Day: Friday, workingHours: 8

>BussinessID: 1, Day: Saturday, workingHours: 8

>BussinessID: 1, Day: Sunday, workingHours: 8
