I have a JSON formatted string that i get from an API call. however the format of the JSON string that i get from the API call is something similar to this.
{"offset":1,"result":{"host":"x.x.x.x","count":123"}}
I want it to be in the following format
{"offset":1,"result":[{"host":"x.x.x.x","count":123"}]}
Note: kindly look at the addition square braces in the folded JSON.
How can i achieve this in PHP . Im fairly new to PHP a little help here is appreciated. Thanks :)

Answer 1

You should be able to do this using PHP's json_decode() and json_encode() functions. Something like:
$jsonFromApi = '{"offset":1,"result":{"host":"x.x.x.x","count":123}}';
$array = json_decode($jsonFromApi, true);
$array['result'] = array($array['result']);
$newJson = json_encode($array);
Edit: Here is an example of using foreach for doing this to a series of comma separated json strings.
$originalData = '{"offset":1,"result":{"host":"x.x.x.x","count":123}},{"offset":2,"result":{"host":"x.x.x.x","count":123}},{"offset":3,"result":{"host":"x.x.x.x","count":123}}';
// Convert original data to valid JSON by wrapping it in brackets []. Makes it a JSON array.
$json = '['.$originalData.']';
$array = json_decode($json, true);
$convertedJsonStrings = array();
foreach ($array as $data) {
$data['result'] = array($data['result']);
$convertedJsonStrings[] = json_encode($data);
}
echo implode(',', $convertedJsonStrings);
Here we can't directly use json_decode() for $originalData since it is not valid JSON as it is.

Answer 2

Convert original into JSON object, take out result.
var originalJSONObj = JSON.parse(original);
var result = originalJSONObj.result;
Create another object with modifiedJSONObj.offset = 1 and modifiedJSONObj.result = [] and finally modifiedJSONObj.result.push(result).

Answer 3

In PHP, something like:
$json = '{"offset":1,"result":{"host":"x.x.x.x","count":123}}';
$data = json_decode($json);
$data->result = [$data->result];
$json = json_encode($data);
var_dump($json);

Answer 4

// i fixed the json that you are able to receive from the api
// maybe you could check it also
$data = '{
"offset": 1,
"result": {
"host": "x.x.x.x",
"count": "123"
}
}';
// decode the json from api
$data = json_decode($data, true);
// create new data from decoded data
$new_data = array(
'ofsset' => $data['offset'],
'result' => array(
$data['result']
)
);
// encode it again
echo json_encode($new_data);
