Summary: Extending DateInterval and unable to use $this->days
Status: Open
Type: Bug
Package: Date/time related
Operating System: Cent OS 6.4
PHP Version: 5.4.19
Block user comment: N

New Comment:
You are right.
I have extended DateTime object and overrides the diff method with
public function diff ($datetime2 , $absolute = false){
return new DateInterval(parent::diff($datetime2,$absolute));
}
If you look at the sample code that would be return the DateInterval in the
test namespace.
Since I am overriding the diff method I want to return a DateInterval object
that behaves like it would from \DateTime which includes a populated days
property , but I have no way of setting the days property or telling \DateTime
to return a different DateInterval object, so I am unable to return a
DateInteral object with a days property filled and returned from the diff
method as expected.
The manual says:
If the DateInterval object was created by DateTime::diff(), then this is the
total number of days between the start and end dates. Otherwise, days will be
FALSE.
This is the method I have overridden and I am trying to return a extended
DateInterval object, whilst keeping the all of the DateInterval property's
intact including days.

"I am trying to extend DateTime and DaveInterval to add extra functionality to
the core classes, but I have been unable to write to $this->days internally to
the object."
That's not really a bug. "days" is a calculated version that only make sense in
the context of having compared two other DateTime objects. Without those other
two objects presents, its value makes no sense.

Description:
------------
I am trying to extend DateTime and DaveInterval to add extra functionality to
the core classes, but I have been unable to write to $this->days internally to
the object.
As a side note, I have been able to cause a seg fault within our application
when writing to $interval->days = 100 externally, but unable to reproduce on a
small script.
Test script:
