Answer 1

strtotime's magic can do this

$start = '09:00:00';
$end = '16:00:00';
$time = strtotime($start);
$timeStop = strtotime($end);

while($time<$timeStop) {
    echo date('H:i', $time);
    $time = strtotime('+30 minutes', $time);
    echo ' - ' . date('H:i', $time) . '
';
}

Result:

09:30 - 10:00
10:00 - 10:30
10:30 - 11:00
11:00 - 11:30
11:30 - 12:00
12:00 - 12:30
12:30 - 13:00
13:00 - 13:30
13:30 - 14:00
14:00 - 14:30
14:30 - 15:00
15:00 - 15:30
15:30 - 16:00
