如何在PHP中的两个日期之间获得差异

I wanted to calculate the difference between two dates in month with PHP but it seems like there is a bug somewhere.

$datetime1 = new DateTime(date('Y-m-d'));
$datetime2 = new DateTime(MyObject->getDate());
echo($datetime1->format('d/m/Y'));
echo($datetime2->format('d/m/Y));

Result:

29/01/2016
27/01/2015

$dateInterval = $datetime1->diff($datetime2);
echo($dateInterval->format(%m months);

Result:

0 months

Why is that? What am i doing wrong ?

    $currentDateTime = new DateTime;
    $dateTimeInTheFuture = new DateTime(MyObject->getDate());
    
    $dateInterval = $dateTimeInTheFuture->diff($currentDateTime);
    
    $totalMonths = 12 * $dateInterval->y + $dateInterval->m;
    
    echo $totalMonths;
