我有一个Laravel应用程序，其中我需要以15分钟的间隔显示上午9点到凌晨3点之间的所有时隙。时隙不包含日期，只包含时间格式，如(AM和PM(

Answer 1

您的碳CarbonPeriod

use CarbonCarbonPeriod;

$period = new CarbonPeriod('03:00', '15 minutes', '14:00'); // for create use 24 hours format later change format 
$slots = [];
foreach($period as $item){
array_push($slots,$item->format("h:i A"));
}
return $slots;

---

根据您的要求。你需要像这样使用

$today =  today()->format('Y-m-d') . " 2:00 PM";
$tomorrow =  today()->addDays('1')->format('Y-m-d')  . " 3:00 AM";
$period = new CarbonPeriod(new Carbon($today), '15 minutes', new Carbon($tomorrow));
$slots = [];
foreach ($period as $item) {
array_push($slots, $item->format("h:i A"));
}

它重新运行

Answer 2

这里有一个框架无关函数

/**
* get a list of hours btw two range
*
* @param int  $lower  start hours in secondes
* @param int  $upper  end hours in secondes
* @param int  $step   hop btw hours in seconde
* @param null $format output hours format
*
* @return array with hours range interval  
* Exemple of use: // Every 30 Minutes from 8 AM - 5 PM, using Custom Time Format:  hoursRange( 28800, 61200, 60 * 30, 'h:i a' );
*/
function hoursRange($lower = 0, $upper = 86400, $step = 1800, $format = 'H:i')
{
$times = [];

if (empty($format))
{
$format = 'H:i';
}

foreach (range($lower, $upper, $step) as $increment)
{
$increment = gmdate('H:i', $increment);
list($hour, $minutes) = explode(':', $increment);

$date = new DateTime($hour.':'.$minutes);

$times[(string)$increment] = $date->format($format);
}

return $times;
}

输出使用示例：

hoursRange(0, 86400, 1800, 'H:i')
