Ability to call toJSON() over a search result

[destegabry]

Maybe I'm doing something wrong, I'm going to start using your great and simple class to perform querying in my webapp.
To retrieve a list of users I'm doing this:

$users = new User();
$users = $users->search();

$list = array();
foreach($users as $u)
    array_push($list, $u->toJSON());
$res->body(json_encode($list, JSON_UNESCAPED_SLASHES ));

Is there a better way to achieve this?

Edit:
I'm doing the foreach sillness to avoid the even sillier _id:{$id:"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"} in my results

Interesting idea. The problem is that search() returns an array, so there's no way to add methods at that point. A better solution would be for search() to return an Iterator, then we could add a toJSON() to that (and also save the pre-fetching of all objects). That's definitely something I'd like to do in the future.
For the time being, your code seems like the best solution. (Minor thing: I use search() statically: $users = User::search(); )

I'm watching you for updates! Anyway, thank you so much for sharing your code

I finally implemented the iterator, which also directly gives you a toJSON() method.

So now you can do User::search()->toJSON().
