Create an empty collection

[Raspberry42]

Hello jerome!

Is it possible to add an empty collection? (without document)

I tried this:

public static function addEmptyCollection (string $collection) {
    $db = self::connectFirestore();
    $db->collection($collection)->document('empty')->set([]);
    $db->collection($collection)->document('empty')->delete();
}

But it also removes the collection ...

You have an idea ?
Thank you.

That's not possible by design: if a collection is empty, it is as if it doesn't exist. It's actually a little bit similar to PHP:

$var = null; // exists, but nothing is in it

But, of course, it's not that simple 😅

Ok I understood.
Thanks Jerome!
