Question

我通过邮件将预订信息从php发送到javascript。使用floor($eventTime/(60*60*24)) - floor(time()/(60*60*24));我告诉我的javascript代码根据他们的日期将事件放在哪里。 $eventTime是一个unix时间戳。 E.x. 21日的任何日期都应该进入第一栏，22日的任何一天应该进入第2栏，等等。我做错了什么？以小时为单位的时间影响显示预订的日期，19日和20日的事件是混合的等等，但是我在数天内使用楼层，所以我不明白。要清楚，我想要从现在到另一个日期的天数，但不包括或考虑小时/分钟。因此，如果今天是第10天，无论什么时间（00:00:00 - 23:59:59）10日的任何预订应该将它的“timeFrom”变量表示为0.发生的事情是10日和11日的日期在这个例子中，当第10个应该是0而第11个应该是1时，将0作为“days between”变量发送。

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 .= ".";
    $postString .= $appResult['location'];
    $postString .= ".";
    $postString .= $appResult['time'];
    $postString .= ".";
    $postString .= $appResult['userCount'];
    $postString .= ".";
    $postString .= $appResult['class'];
    $postString .= "!";
}

Answer 1

获取时间差异的最简单方法是使用DateTime::diff ...

$tz = new DateTimeZone('Your/Timezone'); // maybe this comes from the client side
$now = new DateTime('now', $tz);

// get event time as a DateTime object.
// Use DateTime::createFromFormat if the input format is non-US or ambiguous
$eventTime = new DateTime('date/time string from client', $tz);

$diff = $now->diff($eventTime);
$days = $diff->d;

当然，这只会获得两个日期/时间之间的实际完整天数。 DateInterval对象（$diff）中有大量其他与区间相关的信息，例如

$hours = $diff->h;
$minutes = $diff->i;

更新

要为每个日期使用一天的开始，请在调用diff()之前使用此内容...

$now->setTime(0, 0);
$eventTime->setTime(0, 0);

$diff = $now->diff($eventTime);
$days = $diff->d;

注意：如果您的日期间隔超过夏令时阈值

，您仍可能会遇到问题

Answer 2

你应该在进行分割之前休息一下，然后将地板（）更精确地休息。问题可能是楼层功能的调整。我会这样做：

floor(($eventTime-time())/(60*60*24))

Answer 3

你可以使用strtotime函数获取任何日期的时间戳，如下所示

    $current_time = strtotime(date('d-m-Y g:i:s A')); // timestamp of current date/time

    $your_last_date = "10-Jan-2014";
    $last_time = strtotime($your_last_date);


//subtract them

$sub_time = $current_time - $last_time;

// divide by timestamp of 1 day which is 60*60*24 = 86400;
// you will get the days

$days = floor($sub_time/86400); // no of days between previous date and now

Php从现在到日期之间得到了几天
