计算php datetime并转换为小时

Question

I'd like to calculate the difference in hours between two datetimes elements, but I need to have the exact value of it (like a double variable).

How may I do it?

I have no code samples because I got really stucked in this case, I really need the exact hours of this datetime element and I think date_diff can't give this value in a precise way

You seems to look for the getTimestamp method :

<?php

$date1 = DateTime::createFromFormat('Y-m-d H:i:s', '2016-02-10 07:00:00');
$date2 = DateTime::createFromFormat('Y-m-d H:i:s', '2017-03-11 19:00:00');

$diff = diff_hours($date1, $date2);
var_dump($diff);
function diff_hours(DateTime $date1, DateTime $date2) {
    $diff = $date2->getTimestamp() - $date1->getTimestamp();
    return $diff / ( 60 * 60 );
}
