Resetting values in drop down menu

JaneDoe

After the user clicks a button, I would like to reset the chosen value of a drop down menu. For example, if I have the following drop down menus:
<?
for (i =0; i<7; i++){
?>
<span class="style1">Out</span>
<td width=""><select id="stop<? echo $i ?>" name= "stop<? echo $i ?>">
<option value="0" default></option>
<option value="0">12:00 AM</option>
<option value="0.5">12:30 AM</option>
<option value="1">1:00 AM </option>

<?
}
?>

How can I change the option value from 0 to 12:00 AM so that 12:00 AM gets saved to the database (and not the 0)? Is there something in php that I do something like:

stop1 option value = stop1 option text

Please note, for a good reason (and I dont want to get into because its just a long story), I cannot recode the above option values to the following (if I could, I wouldnt be posting this):

Any help is greatly appreciated! =)

The only thing I can think of is an if/else UPDATE statement...

You can have an array

$time_mappings = array(
'0'=>'12:00 AM',
'0.5'=>'12:30 AM',
...etc
);

And then if $POST['stop2'] is '1', then $time_mappings[$POST['stop2']] is '1:00 AM'.

The only drawback is that before you can do that you have to first make sure that $POST['stop2'] and the rest actually do have values that are in the $time_mappings array; but then you need to do that anyway. In fact, the $time_mappings array makes this bit easy as well, because in_array($POST['stop2'], array_keys($time_mappings)) will return true if and only if $_POST['stop2'] actually does contain a sensible value.
