There's a sift.js library, which allows you to use MongoDB syntax to query JavaScript arrays.
I've asked for a such PHP class in my question, and got several answers so far with good examples, but they still have some compatibility and performance issues(which I hope will be corrected).
Now I've found that such library already exists in JavaScript, and as it is pretty like PHP.
I wonder - would it be difficult to port this library to PHP, preserving it's style and look, without using PHP SPL?
