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
$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 ";

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);
}
一便士一英镑:我刚刚回顾了几个解决方案,所有这些方案都使用floor()提供了一个复杂的解决方案,然后四舍五入到26年12个月零2天的解决方案中,原本应该是25年11个月零20天!!!!
这是我对这个问题的看法:可能不优雅,可能编码不好,但如果不计算LEAP年份,则提供了更接近答案的答案,显然闰年可以编码为,但在这种情况下-正如其他人所说,也许您可以提供以下答案:我已经包含了所有测试条件和print_r,以便您可以更清楚地看到结果的构造:在这里,
//设置输入日期/变量::
$ISOstartDate = "1987-06-22";
$ISOtodaysDate = "2013-06-22";
//我们需要将ISO yyyy-mm-dd格式分解为yyyy-mm-d格式,如下所示:
$yDate[]=爆炸('-',$ISOstartDate);print_r($yDate);
$zDate[]=爆炸('-',$ISOtodaysDate);print_r($zDate);
// Lets Sort of the Years!
// Lets Sort out the difference in YEARS between startDate and todaysDate ::
$years = $zDate[0][0] - $yDate[0][0];
// We need to collaborate if the month = month = 0, is before or after the Years Anniversary ie 11 months 22 days or 0 months 10 days...
if ($months == 0 and $zDate[0][1] > $ydate[0][1]) {
$years = $years -1;
}
// TEST result
echo "\nCurrent years => ".$years;
// Lets Sort out the difference in MONTHS between startDate and todaysDate ::
$months = $zDate[0][1] - $yDate[0][1];
// TEST result
echo "\nCurrent months => ".$months;
// Now how many DAYS has there been - this assumes that there is NO LEAP years, so the calculation is APPROXIMATE not 100%
// Lets cross reference the startDates Month = how many days are there in each month IF m-m = 0 which is a years anniversary
// We will use a switch to check the number of days between each month so we can calculate days before and after the years anniversary
switch ($yDate[0][1]){
case 01: $monthDays = '31'; break; // Jan
case 02: $monthDays = '28'; break; // Feb
case 03: $monthDays = '31'; break; // Mar
case 04: $monthDays = '30'; break; // Apr
case 05: $monthDays = '31'; break; // May
case 06: $monthDays = '30'; break; // Jun
case 07: $monthDays = '31'; break; // Jul
case 08: $monthDays = '31'; break; // Aug
case 09: $monthDays = '30'; break; // Sept
case 10: $monthDays = '31'; break; // Oct
case 11: $monthDays = '30'; break; // Nov
case 12: $monthDays = '31'; break; // Dec
};
// TEST return
echo "\nDays in start month ".$yDate[0][1]." => ".$monthDays;
// Lets correct the problem with 0 Months - is it 11 months + days, or 0 months +days???
$days = $zDate[0][2] - $yDate[0][2] +$monthDays;
echo "\nCurrent days => ".$days."\n";
// Lets now Correct the months to being either 11 or 0 Months, depending upon being + or - the years Anniversary date
// At the same time build in error correction for Anniversary dates not being 1yr 0m 31d... see if ($days == $monthDays )
if($days < $monthDays && $months == 0)
{
$months = 11; // If Before the years anniversary date
}
else {
$months = 0; // If After the years anniversary date
$years = $years+1; // Add +1 to year
$days = $days-$monthDays; // Need to correct days to how many days after anniversary date
};
// Day correction for Anniversary dates
if ($days == $monthDays ) // if todays date = the Anniversary DATE! set days to ZERO
{
$days = 0; // days set toZERO so 1 years 0 months 0 days
};
echo "\nTherefore, the number of years/ months/ days/ \nbetween start and todays date::\n\n";
printf("%d years, %d months, %d days\n", $years, $months, $days);
最终结果是:26年零个月零天
这就是我在2013年6月22日做生意的时间——哎呦!
对于php版本>=5.3:创建两个日期对象,然后使用date_diff()函数。它将返回phpDateInterval对象。请参阅文档
$date1=date_create("2007-03-24");
$date2=date_create("2009-06-26");
$diff=date_diff($date1,$date2);
echo $diff->format("%R%a days");
我不知道你是否在使用PHP框架,但很多PHP框架都有日期/时间库和助手来帮助你避免重新发明轮子。
例如,CodeIgniter具有timespan()函数。只需输入两个Unix时间戳,就会自动生成如下结果:
1 Year, 10 Months, 2 Weeks, 5 Days, 10 Hours, 16 Minutes
http://codeigniter.com/user_guide/helpers/date_helper.html
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
