您只需检查CarbonPeriod是否包含您检查的日期：

$from = '2022-11-01';
$to = '2022-11-05';
$date = Carbon\CarbonPeriod::create($from, $to);
if ($date->contains('2022-11-03')) {
    echo 'Got it';
}

它被要求提供一个带有CarbonPeriod的解决方案。但是，如果你只想检查日期是否介于$from和$to之间，则between是更好的选择。

$from = "2022-11-01";
$to = "2022-11-05";
$check = "2022-11-03";
if(Carbon::parse($check)->between($from,$to)){
  echo $check.' is between '.$from.' and '.$to;
} else {
  echo $check.' is not between '.$from.' and '.$to;
}

Try Carbon
如果数据的格式都是yyyy-mm-dd，则简单的字符串比较就足够了。

$from = "2022-11-01";
$to = "2022-11-05";
$check = "2022-11-03";
if($from <= $check AND $check <= $to) {
  echo $check.' is between '.$from.' and '.$to;
} else {
  echo $check.' is not between '.$from.' and '.$to;
}

根据这个问题，可能是您没有使用parse方法来解析日期，所以这可能是问题所在。

$from = "2022-11-01";
        $to = "2022-11-05";
        $dates = CarbonPeriod::create(
            Carbon::parse($from),
            Carbon::parse($to),
        );
        $dateArray = [];
        foreach ($dates as $date) {
            $dateArray[] = $date->toDateString();
        }

这里，$dateArray为您提供了日期数组。
此外，if部分对于上述解决方案也能正常工作：

if(in_array('2022-11-03', $date)){
    echo "Got it";
}
