Answer 1

Have you looked at the API on json_encode of PHP? You just need to get inside your array specifically what value you want returned to the user. Example:

$objectJson= [
  'nome'=>$seuArray['retorno']['contato']['nome']
];
json_encode($objetoJson);
// A saída deve ser: {"nome":"Nome pego do array"}
