php - 范围时间与 php 中的间隔

Question

我正在用 PHP 创建一个每日计划程序，我每 30 分钟写一个表行并检查约会是否匹配。但是，我遇到部分约会时间问题，例如我必须检查时间:15:34:58 - 16:34:58，我在 15:30 之间没有匹配 和 16:00。这是我的代码:

try {
    $inizio=new DateTime($r["data"]." ".$r["ora"]); // for me is 15:34:58
    $fine=new DateTime($r["data_fin"]." ".$r["ora_fin"]); // for me is 16:34:58
    $timetoCheck=new DateTime(date("Y-m-d")." ".$h.":".$m.":00"); //dinamically change in 15:30 16:00 and so on..
    $intervallo=new DateInterval("PT30M");
    $range=new DatePeriod($inizio, $intervallo, $fine);
    foreach ($range as $fase){
        if (($timetoCheck>=$inizio) and ($timetoCheck<=$fine)) {
            echo $fase->format("H:i:s")." ". $inizio->format("H:i:s")." - ".$fine->format("H:i:s")."<br/><a href='#' id='evento_".$r["key_id"]."'>".$r["titolo"]."</a><br/>";
        }
    }
} catch (Exception $ecc){
    $logger->error($ecc->getMessage());
}

尝试不同的时间比较方式？

$dateTime = new DateTime("15:40:10");
$startTime = new DateTime("15:30:00");
$endTime = new DateTime("16:00:00");
if ($dateTime->diff($startTime)->format('%R') == '-' && $dateTime->diff($endTime)->format('%R') == '+') {
    // current time is within the appointment period
} else {
    // current time is either before or after the appointment period
}
