How to use date difference as an integer in PHP

Question

I have found various methods to calculate the number of dates between 2 dates by first using date_create() and passing it the dates (without time) and then using ->diff on one of the them and works perfectly fine.

However when I attempt to do some integer related operations on it, such as comparing it if difference is >0 then it shows an error :

Object of class DateInterval could not be converted to integer

I have used var_dump() and it shows the value in it stores as string, but intval() is also not successful over it. Any other way to change it to integer?

Code is as follows:

$d1 = date_create(); //get current server time
$d2 = date_create("2020-02-01");//some future date
$diff = $d1->diff($d2);

echo $diff->days; //works fine & displays result perfectly
if($diff->days > 30) {echo "month of difference";} //error here

Works for me, so the error isn't there. https://3v4l.org/EZkMn — Charlotte Dunois, Feb 12 '17 at 10:02
You should possibly take a look at the whole error, as it says where the error definitely oncurrs. — Charlotte Dunois, Feb 12 '17 at 10:04
@CharlotteDunois it is showing line number for error at the above mentioned line only — Lincoln, Feb 12 '17 at 14:02
How about subtracting timestamps? See here http://stackoverflow.com/questions/3176609/calculate-total-seconds-in-php-dateinterval — Nitin, Feb 12 '17 at 14:09
Running your code on PHP7 produces the output `1083month of difference` for me without any errors. The cause of the issue must be somewhere else. — SeinopSys, Feb 12 '17 at 14:09

How about using this in order to convert into integer

$diffDays= intval($diff->format("%d"));
if($diffDays > 30) {echo "month of difference";} //error here probably

It isn't, it's a javascript function. – Charlotte Dunois Feb 12 '17 at 14:03
