复选框值数组

I am trying to get the values of selected check boxes within a form however I need to store an array within the value tag which holds an ID and the Day.

Something like so:

echo '<label><input type="checkbox" name="check_list[ind]" id="'.$ind['ID'].'" value="'.$valueArr[$ind['ID']]['Fri'].'">Friday</label>';

echo '<label><input type="checkbox" name="check_list[grp]" id="'.$ind['ID'].'" value="'.$valueArr[$ind['ID']]['Sat'].'">Sat</label>';


if (isset($_POST['check_list'])){
    $indchks = $_POST['check_list']['ind'];
    $grpchks = $_POST['check_list']['grp'];

    $G = count($grpchks);
    $N = count($indchks);

    for($i = 0; $i < $N; $i++){
        //Need to somehow delve into the value array?
        //insertIndBooking($talent_id, $id, $day);
    }

These values will later have to be read and posted to a DB. My problem being, I am not so certain what I am doing is correct or how I am going to read this array.

Any and all help is gratefully received

Kind Regards,
