Load a JSON string into a data structure.
Also, create a new data structure and serialize it into JSON.

Use objects and arrays (as appropriate for your language)
and make sure your JSON is valid (https://jsonformatter.org).

$data = json_decode(''{ "foo": 1, "bar": [10, "apples"] }'');
 
$sample = ["blue" => [1, 2], "ocean" => "water"];
$jsonstring = json_encode($sample, ["pretty_print" => true]);
