PHP从现在到日期之间的天数

我通过邮寄将预订信息从php发送到javascript。使用floor($eventTime/(60*60*24)) - floor(time()/(60*60*24));我告诉我的javascript代码，根据事件的日期将事件放置在何处。$eventTime是Unix时间戳。例如，在21号的任何日期都应该放在第一个方框中，在22号的任何一天都应该放在方框2中，依此类推。我在做什么错了？以小时为单位的时间会影响显示预订的日期，在19日和20日发生的事件混合在一起，等等，但是我将发言时间设置为天数，所以我不明白。明确地说，我想要从现在到另一个日期的天数，但不包括或不考虑小时/分钟。因此，如果今天是10日，那么10日的任何保留，无论在什么时间（00:00:00-23:59:59）都应将其“ timeFrom”变量表示为0。发生的事情是10日和11日的日期在此示例中，当第10位应为0且第11位应为1时，都将0发送为“ days between”变量。

这是相关的PHP

while ($appResult = $stmt->fetch(PDO::FETCH_ASSOC))
{
    $tz = new DateTimeZone('America/Chicago'); // maybe this comes from the client side
    $now = new DateTime('now', $tz);
    $eventTime = new DateTime($appResult["time"], $tz);
    $now->setTime(0, 0);
    $eventTime->setTime(0, 0);
    $diff = $now->diff($eventTime);
    $days = $diff->d;
    $postString .= $days;
    $postString .= ".";
    $postString .= $appResult['id'];
    $postString .= ".";
    $postString .= date("H.i",strtotime($appResult['time']));
    $postString .= ".";
    $postString .= $appResult['members'];
    $postString .= ".";
    $postString .= $appResult['admin'];
    $postString .= ".";
    $postString .= $appResult['message'];
    $postString .= ".";
    $postString .= $appResult['tools'];
    $postString .= ".";
