PHP date_diff() - find number of days and convert to hours

Question

I wan't to find the date difference between to days and then convert it into hours

$date_diff = date_diff($latest_date, $oldest_date);
echo $date_diff->format(???);

I have tried to set format as ->format('h'); but didn't work. How can I do this?

So do you know how many hours there are in a day? (ignoring daylight savings shifts) — Mark Baker, May 19 '16 at 14:50
24.. you mean to do the math way? I thought php had a build-in functionality to do this — ltdev, May 19 '16 at 14:53

It does have built-in functionality, but not for every conceivable variation; `$totalHours = $date_diff->days * 24 + $date_diff->h;` — Mark Baker, May 19 '16 at 14:58

This should work:

PHP

$datetime1 = date_create('2009-10-11');
$datetime2 = date_create('2009-10-13');
$interval = date_diff($datetime1, $datetime2);

echo 'Days : ' . $interval->days. '  ';
echo 'Hours : ' . $interval->days * 24;
