如何使用PHP找到两个日期之间的天数?
当前回答
$early_start_date = date2sql($_POST['early_leave_date']);
$date = new DateTime($early_start_date);
$date->modify('+1 day');
$date_a = new DateTime($early_start_date . ' ' . $_POST['start_hr'] . ':' . $_POST['start_mm']);
$date_b = new DateTime($date->format('Y-m-d') . ' ' . $_POST['end_hr'] . ':' . $_POST['end_mm']);
$interval = date_diff($date_a, $date_b);
$time = $interval->format('%h:%i');
$parsed = date_parse($time);
$seconds = $parsed['hour'] * 3600 + $parsed['minute'] * 60;
// display_error($seconds);
$second3 = $employee_information['shift'] * 60 * 60;
if ($second3 < $seconds)
display_error(_('Leave time can not be greater than shift time.Please try again........'));
set_focus('start_hr');
set_focus('end_hr');
return FALSE;
}
其他回答
function howManyDays($startDate,$endDate) {
$date1 = strtotime($startDate." 0:00:00");
$date2 = strtotime($endDate." 23:59:59");
$res = (int)(($date2-$date1)/86400);
return $res;
}
如果你使用的是PHP 5.3 >,这是目前为止最准确的计算绝对差值的方法:
$earlier = new DateTime("2010-07-06");
$later = new DateTime("2010-07-09");
$abs_diff = $later->diff($earlier)->format("%a"); //3
如果你需要一个相对的(带符号的)天数,可以用这个代替:
$earlier = new DateTime("2010-07-06");
$later = new DateTime("2010-07-09");
$pos_diff = $earlier->diff($later)->format("%r%a"); //3
$neg_diff = $later->diff($earlier)->format("%r%a"); //-3

尝试使用碳
$d1 = \Carbon\Carbon::now()->subDays(92);
$d2 = \Carbon\Carbon::now()->subDays(10);
$days_btw = $d1->diffInDays($d2);
你也可以用
\Carbon\Carbon::parse('')
使用给定的时间戳字符串创建一个Carbon date对象。
从PHP 5.3及以上版本开始,添加了新的日期/时间函数来获得不同:
$datetime1 = new DateTime("2010-06-20");
$datetime2 = new DateTime("2011-06-22");
$difference = $datetime1->diff($datetime2);
echo 'Difference: '.$difference->y.' years, '
.$difference->m.' months, '
.$difference->d.' days';
print_r($difference);
结果如下:
Difference: 1 years, 0 months, 2 days
DateInterval Object
(
[y] => 1
[m] => 0
[d] => 2
[h] => 0
[i] => 0
[s] => 0
[invert] => 0
[days] => 367
)
希望能有所帮助!
// 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";
