DateInterval d property is 0 instead of real value 28 #18183
Description
Description
The following code:
<?php
$md_1st = new DateTime("2025-03-01");
$md_last = new DateTime("2025-03-29");
$mn_interval = $md_1st->diff($md_last);
echo $mn_interval->days . " " . $mn_interval->d;Resulted in this output:
28 0
But I expected this output instead:
28 28

Anyway, it is working well in 8.1.25

It works on my machine and on 3v4l: https://3v4l.org/EXC9L
Is this maybe timezone related?
bdtarcsa commentedon Mar 29, 2025
I do not know. Maybe. Based on DateTime object the timezone is Europe/Budapest:
object(DateTime)#6 (3) {
["date"]=>
string(26) "2025-03-01 00:00:00.000000"
["timezone_type"]=>
int(3)
["timezone"]=>
string(15) "Europe/Budapest"
}
object(DateTime)#7 (3) {
["date"]=>
string(26) "2025-03-29 00:00:00.000000"
["timezone_type"]=>
int(3)
["timezone"]=>
string(15) "Europe/Budapest"
}

DateTimeInterface::diff the date 2025-02-28 23:00:00 UTC (2025-03-01 00:00:00 Europe/Budapest) is used instead of the real time before php version 8.1..
Why it happens to your php version 8.3.19 is hard to say. Please, Can you test what the timezone_version_get() function returns?
bdtarcsa commentedon Apr 10, 2025
The timezone_version_get() function returns with this:
2025.2

Sorry, I was looking at the wrong version number of PHP.
Correct version numbers are 8.0.30 and 7.4.33.
As I can see in the snipett the result is the same what I detected.
On my dev machine the PHP version is 8.1.25 and timezone version is 2023.3 and there is no problem.
And as I said earlier there was no problem in November for example or in last 8 years. Interesting.

I don't see the issue. As @nielsdos mentions, checking all PHP versions, behaviour is consistent.

These versions have long been out of bugfix support, the lowest bugfix-supported version is 8.3.x. Given that this works in those versions I'm closing this as invalid.
