Php xml data to json encode in specific format - php

Question

This is my php file code where i am fetching data from thecatapi
i needed the specific format for datatable
$xml=file_get_contents('https://thecatapi.com/api/images/get?format=xml&results_per_page=3');
$xml = new SimpleXMLElement($xml);
$datas=array();
$datas['rows'] = $xml->data->images;
echo json_encode($datas, true);
Output is:
{"total":50,
"rows":{"image":[
{"url":"https:\/\/thecatapi.com\/api\/images\/get.php?id=e0i",
"id":"e0i",
"source_url":"http:\/\/thecatapi.com\/?id=e0i"

"id":"MTYwNDE0MQ",
"source_url":"http:\/\/thecatapi.com\/?id=MTYwNDE0MQ"
},{
"url":"https:\/\/thecatapi.com\/api\/images\/get.php?id=bon",

Just came up with an alternativ solution. Change this line:
$datas['rows'] = $xml->data->images;
to this:
$datas['rows'] = $xml->data->images->image;
otherwise you can still do this
Decode the json string into an object and modify it suit your needs.
$stdClassObject = json_decode($jsonData);
$stdClassObject->rows = $stdClassObject->rows->image;
$newJsonData = json_encode($stdClassObject, JSON_PRETTY_PRINT);
echo '<pre>';
print_r($newJsonData);
echo '</pre>';
New output:
{
"total": 50,
"rows": [
{
"url": "https:\/\/thecatapi.com\/api\/images\/get.php?id=e0i",
"id": "e0i",
"source_url": "http:\/\/thecatapi.com\/?id=e0i"
},
{
"url": "https:\/\/thecatapi.com\/api\/images\/get.php?id=MTYwNDE0MQ",
"id": "MTYwNDE0MQ",
"source_url": "http:\/\/thecatapi.com\/?id=MTYwNDE0MQ"
},
{
"url": "https:\/\/thecatapi.com\/api\/images\/get.php?id=bon",
"id": "bon",
"source_url": "http:\/\/thecatapi.com\/?id=bon"
}
]
}
