How to get data from dynamoDB without specifying types?

Question

PHP

I make query/scan requests and receive output in response in the following format:

"timestamp" => [
      "N" => "1513846596"
    ]

It is inconvenient to work with such a format, since there is also a MAP with tons of such nestings
. I can’t find a parameter for building a query in order to receive data in the normal form
"timestamp" => 1513846596
Or build a recursive loop and rebuild it myself?
