Using json_decode to turn a JSON string into an associative array. If it finds duplicate key:value pairs it drops the duplicate.
It would be handy to have an option to keep or not to keep these duplicates.

That's not possible: arrays can't have duplicate keys.

What if it decoded into an array of values? Like {a:1,a:2} decoded to [a=>[1,2]]?

What am I saying? {a:1,a:2} doesn't make sense as JSON either.

Do you have any examples of where this would be useful *and* are not due to flawed JSON encoders?
