我有两个表格日期:
Start Date: 2007-03-24
End Date: 2009-06-26
现在我需要通过以下形式找到这两者之间的区别:
2 years, 3 months and 2 days
如何在PHP中执行此操作?

当前回答
前段时间,我编写了一个format_date函数,因为它提供了许多关于日期的选项:
function format_date($date, $type, $seperator="-")
{
if($date)
{
$day = date("j", strtotime($date));
$month = date("n", strtotime($date));
$year = date("Y", strtotime($date));
$hour = date("H", strtotime($date));
$min = date("i", strtotime($date));
$sec = date("s", strtotime($date));
switch($type)
{
case 0: $date = date("Y".$seperator."m".$seperator."d",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 1: $date = date("D, F j, Y",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 2: $date = date("d".$seperator."m".$seperator."Y",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 3: $date = date("d".$seperator."M".$seperator."Y",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 4: $date = date("d".$seperator."M".$seperator."Y h:i A",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 5: $date = date("m".$seperator."d".$seperator."Y",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 6: $date = date("M",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 7: $date = date("Y",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 8: $date = date("j",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 9: $date = date("n",mktime($hour, $min, $sec, $month, $day, $year)); break;
case 10:
$diff = abs(strtotime($date) - strtotime(date("Y-m-d h:i:s")));
$years = floor($diff / (365*60*60*24));
$months = floor(($diff - $years * 365*60*60*24) / (30*60*60*24));
$days = floor(($diff - $years * 365*60*60*24 - $months*30*60*60*24)/ (60*60*24));
$date = $years . " years, " . $months . " months, " . $days . "days";
}
}
return($date);
}
其他回答
您还可以使用以下代码通过向上舍入分数来返回日期差异$date1=$duedate;//指定到期日echo$date2=日期(“Y-m-d”);//当前日期$ts1=字符串时间($date1);$ts2=字符串时间($date2);$seconds_diff=$ts1-$ts2;echo$datediff=ceil(($seconds_diff/3600)/24);//天内返回
如果您使用php的floor方法而不是ceil,它将返回舍入分数。请检查此处的差异,有时,如果您的临时服务器时区与现场站点时区不同,在这种情况下,您可能会得到不同的结果,因此请相应地更改条件。
对于遗留代码(PHP<5.3)使用此选项。有关最新的解决方案,请参阅下面jurka的答案
您可以使用strtotime()将两个日期转换为unix时间,然后计算它们之间的秒数。由此很容易计算出不同的时间段。
$date1 = "2007-03-24";
$date2 = "2009-06-26";
$diff = abs(strtotime($date2) - strtotime($date1));
$years = floor($diff / (365*60*60*24));
$months = floor(($diff - $years * 365*60*60*24) / (30*60*60*24));
$days = floor(($diff - $years * 365*60*60*24 - $months*30*60*60*24)/ (60*60*24));
printf("%d years, %d months, %d days\n", $years, $months, $days);
编辑:显然,尤尔卡在下面描述了这样做的首选方式。如果您没有PHP5.3或更高版本,通常只建议使用我的代码。
评论中的一些人指出,上面的代码只是一个近似值。我仍然认为,对于大多数目的来说,这是很好的,因为范围的使用更多地是为了提供时间流逝或剩余时间的感觉,而不是为了提供精度-如果你想这样做,只需输出日期。
尽管如此,我还是决定解决这些投诉。如果您确实需要一个精确的范围,但还没有访问PHP 5.3,请使用下面的代码(它也可以在PHP 4中使用)。这是PHP内部用于计算范围的代码的直接端口,但不考虑夏时制。这意味着它最多休息一个小时,但除此之外,它应该是正确的。

我在PHP5.2中遇到了同样的问题,并用MySQL解决了这个问题。可能并不是你想要的,但这会奏效,并返回天数:
$datediff_q = $dbh->prepare("SELECT DATEDIFF(:date2, :date1)");
$datediff_q->bindValue(':date1', '2007-03-24', PDO::PARAM_STR);
$datediff_q->bindValue(':date2', '2009-06-26', PDO::PARAM_STR);
$datediff = ($datediff_q->execute()) ? $datediff_q->fetchColumn(0) : false;

这是我的职责。所需PHP>=5.3.4。它使用DateTime类。非常快,很快,可以区分两个日期,甚至所谓的“开始时间”。

非常简单:
<?php
$date1 = date_create("2007-03-24");
echo "Start date: ".$date1->format("Y-m-d")."<br>";
$date2 = date_create("2009-06-26");
echo "End date: ".$date2->format("Y-m-d")."<br>";
$diff = date_diff($date1,$date2);
echo "Difference between start date and end date: ".$diff->format("%y years, %m months and %d days")."<br>";
?>
