Question

I am working on an appointment script that takes office opening and closing hours from database and then displays the time in between the opening and closing hours to book f

Answer 1

$start    = new DateTime('09:00:00');
$end      = new DateTime('16:00:01'); // add 1 second because last one is not included in the loop
$interval = new DateInterval('PT30M');
$period   = new DatePeriod($start, $interval, $end);

$previous = '';
foreach ($period as $dt) {
    $current = $dt->format("h:ia");
    if (!empty($previous)) {
        echo " {$previous}-{$current}
";
    }
    $previous = $current;
}
