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
当PHP 5.3(分别为date_diff())不可用时,我使用了我编写的以下函数:
function dateDifference($startDate, $endDate)
{
$startDate = strtotime($startDate);
$endDate = strtotime($endDate);
if ($startDate === false || $startDate < 0 || $endDate === false || $endDate < 0 || $startDate > $endDate)
return false;
$years = date('Y', $endDate) - date('Y', $startDate);
$endMonth = date('m', $endDate);
$startMonth = date('m', $startDate);
// Calculate months
$months = $endMonth - $startMonth;
if ($months <= 0) {
$months += 12;
$years--;
}
if ($years < 0)
return false;
// Calculate the days
$measure = ($months == 1) ? 'month' : 'months';
$days = $endDate - strtotime('+' . $months . ' ' . $measure, $startDate);
$days = date('z', $days);
return array($years, $months, $days);
}
其他回答
我投票支持jurka的答案,因为这是我最喜欢的,但我有一个pre-php.5.3版本。。。
我发现自己在解决一个类似的问题——这就是我最初如何回答这个问题——但只是需要时间上的差异。但我的函数也很好地解决了这个问题,而且我自己的库中没有任何地方可以将它保存在不会丢失和遗忘的地方,所以……希望这对某人有用。
/**
*
* @param DateTime $oDate1
* @param DateTime $oDate2
* @return array
*/
function date_diff_array(DateTime $oDate1, DateTime $oDate2) {
$aIntervals = array(
'year' => 0,
'month' => 0,
'week' => 0,
'day' => 0,
'hour' => 0,
'minute' => 0,
'second' => 0,
);
foreach($aIntervals as $sInterval => &$iInterval) {
while($oDate1 <= $oDate2){
$oDate1->modify('+1 ' . $sInterval);
if ($oDate1 > $oDate2) {
$oDate1->modify('-1 ' . $sInterval);
break;
} else {
$iInterval++;
}
}
}
return $aIntervals;
}
测试:
$oDate = new DateTime();
$oDate->modify('+111402189 seconds');
var_dump($oDate);
var_dump(date_diff_array(new DateTime(), $oDate));
结果是:
object(DateTime)[2]
public 'date' => string '2014-04-29 18:52:51' (length=19)
public 'timezone_type' => int 3
public 'timezone' => string 'America/New_York' (length=16)
array
'year' => int 3
'month' => int 6
'week' => int 1
'day' => int 4
'hour' => int 9
'minute' => int 3
'second' => int 8
我从这里得到了最初的想法,我对其进行了修改以供使用(我希望我的修改也会显示在该页面上)。
通过从$aIntervals数组中删除不需要的间隔(例如“周”),或者添加$aExclude参数,或者在输出字符串时过滤掉它们,可以非常容易地删除它们。
“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。。。

使用此函数
//function Diff between Dates
//////////////////////////////////////////////////////////////////////
//PARA: Date Should In YYYY-MM-DD Format
//RESULT FORMAT:
// '%y Year %m Month %d Day %h Hours %i Minute %s Seconds' => 1 Year 3 Month 14 Day 11 Hours 49 Minute 36 Seconds
// '%y Year %m Month %d Day' => 1 Year 3 Month 14 Days
// '%m Month %d Day' => 3 Month 14 Day
// '%d Day %h Hours' => 14 Day 11 Hours
// '%d Day' => 14 Days
// '%h Hours %i Minute %s Seconds' => 11 Hours 49 Minute 36 Seconds
// '%i Minute %s Seconds' => 49 Minute 36 Seconds
// '%h Hours => 11 Hours
// '%a Days => 468 Days
//////////////////////////////////////////////////////////////////////
function dateDifference($date_1 , $date_2 , $differenceFormat = '%a' )
{
$datetime1 = date_create($date_1);
$datetime2 = date_create($date_2);
$interval = date_diff($datetime1, $datetime2);
return $interval->format($differenceFormat);
}
仅根据需要设置参数$differenceFormat例如,我希望你的年龄在到岁之间,以月和日为单位
dateDifference(日期('Y-m-d'),$date,'%Y%m%d')
或其他格式
dateDifference(日期('Y-m-d'),$date,'%Y-%m-%d')
简单的功能
function time_difference($time_1, $time_2, $limit = null)
{
$val_1 = new DateTime($time_1);
$val_2 = new DateTime($time_2);
$interval = $val_1->diff($val_2);
$output = array(
"year" => $interval->y,
"month" => $interval->m,
"day" => $interval->d,
"hour" => $interval->h,
"minute" => $interval->i,
"second" => $interval->s
);
$return = "";
foreach ($output AS $key => $value) {
if ($value == 1)
$return .= $value . " " . $key . " ";
elseif ($value >= 1)
$return .= $value . " " . $key . "s ";
if ($key == $limit)
return trim($return);
}
return trim($return);
}
像这样使用
回波时间差($time_1,$time_2,“天”);
将返回2年8个月2天
