MongoDB query in PHP different collections, same entry, different types, result on a null

Question

I'm actually working on a web server, I need to look for CardNumber in my client collection.

In order to do that, I get all the Bills where I can find my CardNumber

The problem is : in Bills , CardNumber are Int64 , but in client , CardNumber are double . In PHP my query doesn't work, but when i'm doing it on mongo it works.

Here is my code

foreach ($this->bills as $bill)
    {
        $query = [
             //Already tried to cast, floatvar etc...
            'CARDNUM' => doublevar(($bill['CARDNUM']))
        ];
        $result = $collection->findOne($query);
        var_dump($result); //Always null
    }

For exemple, my first $bill['CARDNUM'] gives me 0123456

If I do this db.getCollection('clientCollec').find({"CARDNUM" : 0123456}) in a mongoShell, I have a result.

Thanks for helping
