Question

I was wondering if I could do some performance tuning for the below PHP Script. What I am trying to do – is get every half hour from 00:00am to 23:30pm into a select list. Here is the code

<?php
$starttime = '00:00';
$time = new DateTime($starttime);
$interval = new DateInterval('PT30M');
$temptime = $time->format('H:i');
do{
   echo '<option value="">'.date("H:i a", strtotime($temptime)).'</option>';
   $time->add($interval);
   $temptime = $time->format('H:i');
}while ($temptime !== $starttime);
?>

I believe there is a way we can do it in an easier manner – but I cannot think of it. Can someone help?

foreach (range(0, 60*24, 30) as $minutes) {
    echo '<option>' . date('H:i a', strtotime('00:00 +' . $minutes . ' minutes')) . '</option>';
}
