List to show time

[sfast]

I have to show a select list of time in half an hour interval.
I dont want to insert it manually like -

<option value="oneThirty">1:30AM</option>
<option value="two">2AM</option>

Is there way I can do it using loop in PHP and how?

Thanks

Here you go. This generates values like 1200,1230,1300, which would be easier to process than your textual oneThirty. If you really want to use a textual representation, then you could do an array to convert the hours and conditionally add on 'Thirty' if $mins isn't zero.

<?php
$qty = 10;// How many to generate
// Use this line to start at an arbitrary time:
$st = strtotime('12:00pm',time());
// Uncomment this line to start at current time:
// $st = time();
$mins = date('i',$st);
$hrs = date('G',$st);
// These next lines roll an odd time to the next half-hour interval.
// If you start at an arbitrary time, you can comment/delete
// From here - - - - -
if($mins > 30) {
$mins = 0;
$hrs++;
}
elseif($mins > 0)
$mins = 30;
$st = strtotime("$hrs:$mins",time());
// - - - to here
for($i = 0; $i < $qty; $i++) {
echo '<option value="' . sprintf('%02d%02d',$hrs,$mins) . '">' . date('g:i a',$st) . "</option>\n";
$st += 1800;// 30 minutes
$hrs = date('G',$st);
$mins = date('i',$st);
}// EndFor
?>

Here is another way that starts at 12:00am

$t = strtotime("Midnight"); // set this to your start point...:)
echo "<select name=\"whatever\">\n";
for($i=0; $i<48; $i++)
{
echo "\t<option value=\"" . strftime("%I:%M%p", $t) . "\">" . strftime("%I:%M%p", $t) . "</option>\n";
$t += (30 * 60);
}
echo "</select>";
