在PHP中，有没有办法在一组时间中找到最近的时间？

$times = array('10:00', '12:30', '15:45', '18:20');
$targetTime = '14:00';

$closestTime = null;
$closestDiff = null;

foreach ($times as $time) {
    $diff = date_diff(date_create($time), date_create($targetTime));
    $minutesDiff = $diff->format('%i');

    if ($closestDiff === null || $minutesDiff < $closestDiff) {
        $closestTime = $time;
        $closestDiff = $minutesDiff;
    }
}

echo "最近的时间是：" . $closestTime;
