如何使用PHP找到两个日期之间的天数?
当前回答
function howManyDays($startDate,$endDate) {
$date1 = strtotime($startDate." 0:00:00");
$date2 = strtotime($endDate." 23:59:59");
$res = (int)(($date2-$date1)/86400);
return $res;
}

使用这个:)
$days = (strtotime($endDate) - strtotime($startDate)) / (60 * 60 * 24);
print $days;
现在起作用了
使用这个简单的函数。声明函数
<?php
function dateDiff($firstDate,$secondDate){
$firstDate = strtotime($firstDate);
$secondDate = strtotime($secondDate);
$datediff = $firstDate - $secondDate;
$output = round($datediff / (60 * 60 * 24));
return $output;
}
?>
像这样调用这个函数
<?php
echo dateDiff("2018-01-01","2018-12-31");
// OR
$firstDate = "2018-01-01";
$secondDate = "2018-01-01";
echo dateDiff($firstDate,$secondDate);
?>
$datediff = floor(strtotime($date1)/(60*60*24)) - floor(strtotime($date2)/(60*60*24));
如果需要的话:
$datediff=abs($datediff);
易于使用date_diff
$from=date_create(date('Y-m-d'));
$to=date_create("2013-03-15");
$diff=date_diff($to,$from);
print_r($diff);
echo $diff->format('%R%a days');

// Change this to the day in the future
$day = 15;
// Change this to the month in the future
$month = 11;
// Change this to the year in the future
$year = 2012;
// $days is the number of days between now and the date in the future
$days = (int)((mktime (0,0,0,$month,$day,$year) - time(void))/86400);
echo "There are $days days until $day/$month/$year";
