Successive calls to Zipper::make() return the same object

[Bunobuno]

Hi,

I need to work on two different archives at the same time, thus I am trying to get two instances of Zipper to work on. I'm stuck because it seems that successive calls to make() will simply overwrite any previous instance:

$a=Zipper::make('a.zip');
$b=Zipper::make('b.zip');

The two objects become identical after the second call

>>> $a===$b;
=> true

and the internal properties of $a seem to have been overriden by these of $b

>>> print_r($a);
Chumper\Zipper\Zipper Object
(
    [currentFolder:Chumper\Zipper\Zipper:private] =>
    [file:Chumper\Zipper\Zipper:private] => Illuminate\Filesystem\Filesystem Object
        (
        )

    [repository:Chumper\Zipper\Zipper:private] => Chumper\Zipper\Repositories\ZipRepository Object
        (
            [archive:Chumper\Zipper\Repositories\ZipRepository:private] => ZipArchive Object
                (
                    [status] => 0
                    [statusSys] => 0
                    [numFiles] => 17
                    [filename] => /media/project/storage/app/b.zip
                    [comment] =>
                )

        )

    [filePath:Chumper\Zipper\Zipper:private] => /media/project/storage/app/b.zip
)
=> true

Is there a solution to work on multiple instances at the same time?

Thanks
