get a time difference between two dates

问题:

I would like compare the two dates to get a time (Days, Hours, minutes and seconds) difference in TWIG

{% set todayDate = ( "now"| date("Y-m-d H:i:s") ) %}  //2013-04-17 08:45:28 
{% set endDate =  (enddate|date('Y-m-d H:i:s')) %}    //2013-04-18 23:59:59

How to get hours difference?

回答1:

Finally i got it.. compare the two dates to get a time (Days, Hours and minutes) in controller :

(doctrine query)

TIMESTAMPDIFF(DAY,CURRENT_TIMESTAMP(), a.enddate) AS endday,    
(TIMESTAMPDIFF(HOUR,CURRENT_TIMESTAMP(), a.enddate) - TIMESTAMPDIFF(DAY,CURRENT_TIMESTAMP(),a.enddate)*24) AS endhour,
(TIMESTAMPDIFF(MINUTE,CURRENT_TIMESTAMP(), a.enddate) - TIMESTAMPDIFF(HOUR,CURRENT_TIMESTAMP(), a.enddate)*60) AS endmin,

Created a function for TIMESTAMPDIFF https://github.com/beberlei/DoctrineExtensions/blob/master/lib/DoctrineExtensions/Query/Mysql/TimestampDiff.php

and include a snippet

app->config->config.yml doctrine: dbal: ........

orm:
    entity_managers:
        default:
            auto_mapping: true
            dql:
                datetime_functions:
                    timestampdiff: Acme\BUNDLE\FOLDER\TimestampDiff

Thanks to all ..

Since you pass the enddate to your template, you should do this in your controller and pass the result to your template.

Here is the php code you could use:

$now = new DateTime('now');
$dateToCompare = new DateTime('your date');

$difference = $now->format('U') - $dateToCompare->format('U');
// or if your date to compare is in the future :
// $difference = $dateToCompare->format('U') - $now->format('U');
$time_diff = gmdate('H',$difference);

echo $time_diff;
