计算剩余天数

Question

我想计算一个约会前的剩余天数.在我的数据库中,我有一个与结束日期相对应的时间戳.例如星期五30号.我想说的是这样的话:

剩下7天...... 6,5,4等

你能帮我吗 ？

Answer 1

$future = strtotime('21 July 2012'); //Future date.
$timefromdb = //source time
$timeleft = $future-$timefromdb;
$daysleft = round((($timeleft/24)/60)/60); 
echo $daysleft;

Answer 2

  $date1 = new DateTime("2016-01-01");  //current date or any date
  $date2 = new DateTime("2016-12-31");   //Future date
  $diff = $date2->diff($date1)->format("%a");  //find difference
  $days = intval($diff);   //rounding days
  echo $days;
  //it return 365 days omitting current day
