    <option value="15:00:00">15:00:00</option>
    <option value="15:30:00">15:30:00</option>
    <option value="16:00:00">16:00:00</option>
    <option value="16:30:00">16:30:00</option>
    <option value="17:00:00">17:00:00</option>
    <option value="17:30:00">17:30:00</option>
    <option value="18:00:00">18:00:00</option>
    <option value="18:30:00">18:30:00</option>
    <option value="19:00:00">19:00:00</option>
    <option value="19:30:00">19:30:00</option>
    <option value="20:00:00">20:00:00</option>
    <option value="20:30:00">20:30:00</option>
    <option value="21:00:00">21:00:00</option>
    <option value="21:30:00">21:30:00</option>
    <option value="22:00:00">22:00:00</option>
    <option value="22:30:00">22:30:00</option>
    <option value="23:00:00">23:00:00</option>
    <option value="23:30:00">23:30:00</option>
</select>

Is there a way to make it a little bit more dynamic, instead of having this huge html ?

Something like this

<?php foreach (date('H:i:s') as $time): ?>
    <option value="<?php echo $time; ?>"><?php echo $time; ?></option>
<?php endforeach; ?>

Why don't you have two drop downs - 1 for hour and 1 for month, seconds are constant in your case - 0 — Thamilhan

This is what I already have. one for date and one for time, like you said — ltdev

You can use while loop to make it,

<?php
    $start = "00:00"; //you can write here 00:00:00 but not need to it
    $end = "23:30";

    $tStart = strtotime($start);
    $tEnd = strtotime($end);
    $tNow = $tStart;
    echo '<select name="schedule_time">';
    while($tNow <= $tEnd){
        echo '<option value="'.date("H:i:s",$tNow).'">'.date("H:i:s",$tNow).'</option>';
        $tNow = strtotime('+30 minutes',$tNow);
    }
    echo '</select>';
?>

Best and simplest method:

<select>
<?php 
for($hours=0; $hours<24; $hours++)
{
    for($mins=0; $mins<60; $mins+=30)
    { 
        $time = str_pad($hours,2,'0',STR_PAD_LEFT).':'.str_pad($mins,2,'0',STR_PAD_LEFT).':00';
        echo '<option value= "'.$time.'">'.$time.'</option>';
    }
}
?>
</select>

hey you can try this code, you can take whatever range $start and $end variable .

  <?php
$start = "12:00:00";
$end = "24:00:00";

$tStart = strtotime($start);
$tEnd = strtotime($end);
$tNow = $tStart;
?>
<select name="schedule_time">
<?php
while($tNow <= $tEnd){ ?>

    <option value="<?php  echo date("H:i:s",$tNow); ?>"> <?php echo date("H:i:s",$tNow);?></option>
    <?php

  $tNow = strtotime('+30 minutes',$tNow);
}
?>

Try with this code.

 <?php 
        $start = '00:00AM';
        $end = '11:59PM';
        $interval = '+30 minutes';
        $now_str = strtotime($start);
        $end_str = strtotime($end);
        echo '<select name="schedule_time">';
        while($now_str <= $end_str){
            ?>
            <option value="<?php echo date('H:i A', $now_str);?>" ><?php echo date('H:i A', $now_str);?></option>
        <?php
        }
         echo '</select>';
 ?>
