datetime - get php DateInterval in total 'minutes'

Question

I am trying to get the PHP "DateInterval" value in "total minutes" value. How to get it? Seems like simple format("%i minutes") not working?

Here is the sample code:

$test = new DateTime("48 hours");
$interval = $test->diff(new DateTime());

Now if I try to get the interval in total days, its fine:

echo $interval->format('%a total days');

It is showing 2 days as output, which is totally fine. What I am trying to get if to get the value in "total minutes", so I tried:

echo $interval->format('%i total minutes');

Which is not working. Any help appreciated to get my desired output.

Answer 1

abs((new DateTime("48 hours"))->getTimestamp() - (new DateTime)->getTimestamp()) / 60

That's the easiest way to get the difference in minutes between two DateTime instances.
