如何使用PHP找到两个日期之间的天数?
当前回答
PHP中两个日期之间的天数
function dateDiff($date1, $date2) //days find function
{
$diff = strtotime($date2) - strtotime($date1);
return abs(round($diff / 86400));
}
//start day
$date1 = "11-10-2018";
// end day
$date2 = "31-10-2018";
// call the days find fun store to variable
$dateDiff = dateDiff($date1, $date2);
echo "Difference between two dates: ". $dateDiff . " Days ";

$dateDiff = dateDiff($date1, $date2);
echo "Difference between two dates: ". $dateDiff . " Days ";
你可以试试下面的代码:
$dt1 = strtotime("2019-12-12"); //Enter your first date
$dt2 = strtotime("12-12-2020"); //Enter your second date
echo abs(($dt1 - $dt2) / (60 * 60 * 24));
如果你有以秒为单位的时间(即unix时间戳),那么你可以简单地减去时间并除以86400(秒/天)
使用这个:)
$days = (strtotime($endDate) - strtotime($startDate)) / (60 * 60 * 24);
print $days;
现在起作用了
我阅读了所有以前的解决方案,没有一个使用PHP 5.3工具:DateTime::Diff和DateInterval::Days
DateInterval::Days精确地包含日期之间的天数。没有必要创造一些特别和奇异的东西。
/**
* We suppose that PHP is configured in UTC
* php.ini configuration:
* [Date]
* ; Defines the default timezone used by the date functions
* ; http://php.net/date.timezone
* date.timezone = UTC
* @link http://php.net/date.timezone
*/
/**
* getDaysBetween2Dates
*
* Return the difference of days between $date1 and $date2 ($date1 - $date2)
* if $absolute parameter is false, the return value is negative if $date2 is after than $date1
*
* @param DateTime $date1
* @param DateTime $date2
* @param Boolean $absolute
* = true
* @return integer
*/
function getDaysBetween2Dates(DateTime $date1, DateTime $date2, $absolute = true)
{
$interval = $date2->diff($date1);
// if we have to take in account the relative position (!$absolute) and the relative position is negative,
// we return negatif value otherwise, we return the absolute value
return (!$absolute and $interval->invert) ? - $interval->days : $interval->days;
}
echo '<h3>2020-03-01 - 2020-02-01: 29 days as it\'s a standard leap year</h3>';
echo getDaysBetween2Dates(new DateTime("2020-03-01"), new DateTime("2020-02-01"), false);
echo '<h3>1900-03-01 - 1900-02-01: 28 days as it\'s a "standard" century</h3>';
echo getDaysBetween2Dates(new DateTime("1900-03-01"), new DateTime("1900-02-01"), false);
echo '<h3>2000-03-01 - 2000-02-01: 29 days as it\'s a century multiple of 400: 2000=400x5</h3>';
echo getDaysBetween2Dates(new DateTime("2000-03-01"), new DateTime("2000-02-01"), false);
echo '<h3>2020-03-01 - 2020-04-01: -28 days as 2020-03-01 is before 2020-04-01</h3>';
echo getDaysBetween2Dates(new DateTime("2020-02-01"), new DateTime("2020-03-01"), false);
