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
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。

“如果”日期存储在MySQL中,我发现在数据库级别进行差异计算更容易。。。然后根据“天”、“小时”、“分钟”、“秒”输出,分析并显示相应的结果。。。
mysql> select firstName, convert_tz(loginDate, '+00:00', '-04:00') as loginDate, TIMESTAMPDIFF(DAY, loginDate, now()) as 'Day', TIMESTAMPDIFF(HOUR, loginDate, now())+4 as 'Hour', TIMESTAMPDIFF(MINUTE, loginDate, now())+(60*4) as 'Min', TIMESTAMPDIFF(SECOND, loginDate, now())+(60*60*4) as 'Sec' from User_ where userId != '10158' AND userId != '10198' group by emailAddress order by loginDate desc;

4 rows in set (0.00 sec)
$date1 = date_create('2007-03-24');
$date2 = date_create('2009-06-26');
$interval = date_diff($date1, $date2);
echo "difference : " . $interval->y . " years, " . $interval->m." months, ".$interval->d." days ";
使用示例:
echo time_diff_string('2013-05-01 00:22:35', 'now');
echo time_diff_string('2013-05-01 00:22:35', 'now', true);
输出:
4 months ago
4 months, 2 weeks, 3 days, 1 hour, 49 minutes, 15 seconds ago
功能:
function time_diff_string($from, $to, $full = false) {
$from = new DateTime($from);
$to = new DateTime($to);
$diff = $to->diff($from);
$diff->w = floor($diff->d / 7);
$diff->d -= $diff->w * 7;
$string = array(
'y' => 'year',
'm' => 'month',
'w' => 'week',
'd' => 'day',
'h' => 'hour',
'i' => 'minute',
's' => 'second',
);
foreach ($string as $k => &$v) {
if ($diff->$k) {
$v = $diff->$k . ' ' . $v . ($diff->$k > 1 ? 's' : '');
} else {
unset($string[$k]);
}
}
if (!$full) $string = array_slice($string, 0, 1);
return $string ? implode(', ', $string) . ' ago' : 'just now';
}
使用date_diff()尝试这个非常简单的答案,这是经过测试的。
$date1 = date_create("2017-11-27");
$date2 = date_create("2018-12-29");
$diff=date_diff($date1,$date2);
$months = $diff->format("%m months");
$years = $diff->format("%y years");
$days = $diff->format("%d days");
echo $years .' '.$months.' '.$days;
输出为:
1 years 1 months 2 days
