PHP和MySQL中的日期时间之间的差异

Question

I have 2 dates from mysql with datetime format.

Date 1 is:

"2012/09/28 09:28:00" (column name is departure_date)

and Date 2 is:

"2012/09/29 10:48:00" (column name is return_date)

So how to get a result like this: "25 hours 20 minutes"

I don't care about the seconds.

I'm using MySQL and PHP for the programming language.

Answer 1

Date difference function already exists

SELECT DATEDIFF('2007-10-04 11:26:00','2007-10-04 11:50:00')

Also you can try TimeDiff

SELECT TIMEDIFF('2007-10-05 12:10:18','2007-10-05 16:14:59') AS duration;

So in your case you have the option to use these two functions like this

SELECT TIMEDIFF(departure_date,return_date) AS duration;
SELECT DATEDIFF(departure_date,return_date) AS duration;

Answer 2

You could use DateInterval class.

$date1 = new DateTime("2012/09/28 09:28:00");
$date2 = new DateTime("2012/09/29 10:48:00");

$diff = $date1->diff($date2);
echo $diff->format('%d days %h hours %i minutes');

Check here for the format.

Answer 3

You can do it example by this:

$date1 = "2012/09/28 09:28:00";
$date2 = "2012/09/29 10:48:00";

$difference = abs(strtotime($date2)-strtotime($date1));

$hours = floor($difference / (60*60));
$minutes = floor(($difference - $hours * 60*60) / 60);

echo "{$hours} hours {$minutes} minutes";

And it will give you exactly what are you looking for:

25 hours 20 minutes

Answer 4

try this:

select concat(substr(mt,1,locate('.',mt)-1),' hours') hours,
       concat(ceil((substr(mt,locate('.',mt)+1) * .60)/100 ),' minutes') 
                                                                     as minutes
from (
select TIMESTAMPDIFF(MINUTE,
                      '2012/09/28 09:28:00','2012/09/29 10:48:00')/60 as mt)a
