PHP: Days, hours and minutes left to a certain date? -

i'm trying remaining days, hours , minutes date using php.

however strange output code looks this:

-16828 days , -11 hours , -21 minutes , -24 seconds  

the future dates stored in mysql database in format:

29/01/2016 7pm 

so went ahead , done this:

$draw_time = "29/01/2016 7pm";  $date = $draw_time; $timestamp = strtotime($date); $new_date = date('y-m-d a',$timestamp );  $seconds = strtotime($new_date) - time();  $days = floor($seconds / 86400); $seconds %= 86400;  $hours = floor($seconds / 3600); $seconds %= 3600;  $minutes = floor($seconds / 60); $seconds %= 60;   echo "$days days , $hours hours , $minutes minutes , $seconds seconds"; 

but when run code, above strange output!

i understand because of number reasons thing think of fact using a in format?

could please advise on issue?

simply use datetime class as

$draw_time = "29/01/2016 7pm";  $date = datetime::createfromformat("d/m/y ha",$draw_time); $date2 = new datetime();  echo $diff = $date2->diff($date)->format("%a days , %h hours , %i minutes , %s seconds");
