Calculate number of days remaining

Question

I would like to calculate the number of days remaining before a date. In my database I have a timestamp corresponding to the end date. For example Friday 30. I would like to say something like that :

7 days remaining... 6, 5, 4, etc

Can you help me please ?

What's wrong with floor(($endTimestamp - time()) / 86400); ? — Jonnix, Sep 23 '11 at 15:59
Storing timestamps in a database is not good practice. Your DBMS will provide data types which better suits dates. — str, Sep 23 '11 at 16:11

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

Edited. Future should be the date you are **counting down to** – Mob Sep 23 '11 at 16:22
This doesn't go into negatives. – Grasper Dec 21 '17 at 14:30

  $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

Best solution, choose this for Y2K38. – delato468 Sep 16 '20 at 09:16
Just a question, if the date already passed the returned value is negative? – svelandiag Oct 15 '20 at 22:40

@BobbaFett What returns a timestamp? `$days` should be number of days, I'm pretty sure of it. – Stanislav Shabalin Sep 23 '11 at 17:15
This one works the best, just use `strtotime()` for the timestamp – Grasper Dec 21 '17 at 14:48

$date2=date_create("2013-12-12");
$diff=date_diff($date1,$date2);
echo $diff->format("%R%a days");
