CodePudding user response：

You can simply your code by using a mixture of DateTime, DatePeriod and DateInterval:

$start = new DateTime($garage->work_time->from);
$end = new DateTime($garage->work_time->to);
$interval = DateInterval::createFromDateString('30 minutes');

$period = new DatePeriod($start, $interval, $end);

$available_times = [];
foreach ($period as $time) {
    $available_times[] = $time->format('h:i a');
}

return $available_times;

Alternatively, since Laravel comes with Carbon, you could use CarbonPeriod instead:

use Carbon\CarbonPeriod;

$periods = CarbonPeriod::create($garage->work_time->from, '30 minutes', $garage->work_time->to);

$available_times = array_map(function ($period) {
    return $period->format('h:i a');
}, $periods->toArray());

i solved it by change time in DB to 24 hours 17:00:00 instead of 5:00:00 in end time

 $available_times = [];

        $from = date("H:i", strtotime($module->from));
        $to = date("H:i", strtotime($module->to));


        if (!in_array(date("h:i a", strtotime($from)), $available_times)) {
            array_push($available_times, date("h:i a", strtotime($from)));
        }

        $time_from = strtotime($from);

        $new_time = date("H:i", strtotime('30 minutes', $time_from));
        if (!in_array(date("h:i a", strtotime($new_time)), $available_times)) {
            array_push($available_times, date("h:i a", strtotime($new_time)));
        }

        while ($new_time < $to) {
            $time = strtotime($new_time);
            $new_time = date("H:i", strtotime(' 30 minutes', $time));
            if ($new_time . ':00' >= $to) {
                break;
            }
//                //Push 3
            if (!in_array(date("h:i a", strtotime($new_time)), $available_times)) {
                array_push($available_times, date("h:i a", strtotime($new_time)));
            }

        }

        return $available_times;
