在几分钟内找到date_diff？

Question

Can date_diff be used to compute difference in minutes?

$a   = date_create('2016-11-03 00:00:00');
$b   = date_create('2016-11-05 00:19:00');

$dd = date_diff($a, $b);
echo $dd->format('%i');

The above code will return 19 minutes even if it's already been 2 days

Answer 1

Try this

it will output difference in minutes.

$a = new DateTime('2016-11-05 00:00:00');
$b = new DateTime('2016-11-05 00:19:00');
 $diff =  ($b->getTimestamp() - $a->getTimestamp())/60;
 echo $diff;

Answer 2

You can use DateTime()
Get difference in hour , minute , and seconds

$a =   new \DateTime("2016-11-05 00:00:00");
$b =   new \DateTime("2016-11-05 00:19:00");

$dateinterval = $b->diff($a);

$time = sprintf(
    '%d:%02d:%02d',
    ($dateinterval->d * 24) + $dateinterval->h,
    $dateinterval->i,
    $dateinterval->s
);
