How can the JSON output be formatted correctly to avoid the empty dataset issue?

The issue of empty dataset in JSON output can be solved by ensuring that the data being encoded into JSON is not empty. This can be achieved by checking if the data exists before encoding it into JSON format. By implementing a conditional check to ensure that the data is not empty, we can avoid the issue of empty dataset in the JSON output. 

$data = []; // Sample empty dataset

if (!empty($data)) {
    $json_output = json_encode($data);
    echo $json_output;
} else {
    echo json_encode(["error" => "Empty dataset"]);
}
