How to split time left in days,hours,minutes,seconds in query - php

Question

Below is my table structure
Now I am in need of a query in whicn I can display the days,hours,minutes,second left for that event.
I have use this query
select title,`date`,subject ,TIMESTAMPDIFF(DAY, CONVERT_TZ(NOW(),##session.time_zone, '+05:30'),'2013-05-25 12:00:00') as dayleft ,TIMESTAMPDIFF(HOUR, CONVERT_TZ(NOW(),##session.time_zone, '+05:30'),'2013-05-25 12:00:00') as hourleft from jos_holidays where `date` > CONVERT_TZ(NOW(),##session.time_zone, '+05:30')
and the above results me
But my need to get exact time left includes days,hours,minutes and seconds and display it in seperate columns. Can I achive this in query? Though this can be achievable in PHP.
Also the date "2013-05-25 12:00:00" value in query is hard coded . Can be make it dynamic too.
Thanks

Query:
SQLFIDDLEExample
SELECT title,
`date`,
subject ,
TIMESTAMPDIFF(DAY, CONVERT_TZ(NOW(),##session.time_zone, '+05:30'), `date`) AS dayleft,
TIMESTAMPDIFF(HOUR, CONVERT_TZ(NOW(),##session.time_zone, '+05:30'), `date`)
- TIMESTAMPDIFF(DAY, CONVERT_TZ(NOW(),##session.time_zone, '+05:30'), `date`)*24 AS hourleft,
TIMESTAMPDIFF(MINUTE, CONVERT_TZ(NOW(),##session.time_zone, '+05:30'), `date`) -
TIMESTAMPDIFF(HOUR, CONVERT_TZ(NOW(),##session.time_zone, '+05:30'), `date`)* 60 AS minuteleft,
TIMESTAMPDIFF(SECOND, CONVERT_TZ(NOW(),##session.time_zone, '+05:30'), `date`)-
TIMESTAMPDIFF(MINUTE, CONVERT_TZ(NOW(),##session.time_zone, '+05:30'), `date`)*60 AS secondleft
FROM jos_holidays
WHERE `date` > CONVERT_TZ(NOW(),##session.time_zone, '+05:30')

Try like
$diff = strtotime($date) - time();
echo "tile left is ".date('Y-m-d H-m-i',$diff);

Answer 3

In PHP you can use
$now = new DateTime(); // or use any start date you want
$date = new DateTime($row['date']); // your sql query result
$diff = $now->diff($date);
This makes $diff a DateInterval object that contains all the information you are looking for. It does require PHP 5.3+.
I'm not sure if it would be possible to get the same information directly from MySQL. But I would assume that it's mainly for display purposes, so calculating this in PHP from available information is not too much overhead.

Answer 4

its work i have used this query
SELECT
TIMESTAMPDIFF(DAY,NOW(),'2013-06-23') AS dafLeft,
TIMESTAMPDIFF(HOUR,NOW(),'2013-06-23')-TIMESTAMPDIFF(DAY,NOW(),'2013-06-23')*24 AS hourLeft,
TIMESTAMPDIFF(MINUTE,NOW(),'2013-06-23')-TIMESTAMPDIFF(HOUR,NOW(),'2013-06-23')*60 AS minLeft,
TIMESTAMPDIFF(SECOND,NOW(),'2013-06-23')-TIMESTAMPDIFF(MINUTE,NOW(),'2013-06-23')*60 AS secLeft;
For dynamic just '2013-06-23' to your field name (date field name) and fetch like you do in other table.
Happy coding!! :)
