  "1": { "type": 12, "index": 116, "showType": 1, "achievementType": 0, "desc": "WING" },
  "3": { "type": 12, "index": 118, "showType": 1, "achievementType": 0, "desc": "WING" },
  "2": { "type": 12, "index": 117, "showType": 1, "achievementType": 0, "desc": "WING" }

  "2": { "type": 12, "index": 117, "showType": 1, "achievementType": 0, "desc": "WING" },
  "3": { "type": 12, "index": 118, "showType": 1, "achievementType": 0, "desc": "WING" },
  "4": { "type": 12, "index": 119, "showType": 1, "achievementType": 0, "desc": "WING" }
}

Answer 1

Convert to array, sort by index, then convert to obj.

PHP version

$json = '{
    "0": { "type": 12, "index": 115, "showType": 1, "achievementType": 0, "desc": "WING" },
    "4": { "type": 12, "index": 119, "showType": 1, "achievementType": 0, "desc": "WING" },
    "1": { "type": 12, "index": 116, "showType": 1, "achievementType": 0, "desc": "WING" },
    "3": { "type": 12, "index": 118, "showType": 1, "achievementType": 0, "desc": "WING" },
    "2": { "type": 12, "index": 117, "showType": 1, "achievementType": 0, "desc": "WING" }
}';

$obj = json_decode($json, true);
usort($obj, function ($a, $b) {
    if ($a["index"] > $b["index"]) {
        return 1;
    } else if ($a["index"] < $b["index"]) {
        return -1;
    } else {
        return 0;
    }
});

return $obj;
// or
return json_encode($obj);

JS version

 var obj = { "0": { "type": 12, "index": 115, "showType": 1, "achievementType": 0, "desc": "WING" }, "4": { "type": 12, "index": 119, "showType": 1, "achievementType": 0, "desc": "WING" }, "1": { "type": 12, "index": 116, "showType": 1, "achievementType": 0, "desc": "WING" }, "3": { "type": 12, "index": 118, "showType": 1, "achievementType": 0, "desc": "WING" }, "2": { "type": 12, "index": 117, "showType": 1, "achievementType": 0, "desc": "WING" } } function sort_obj_by_index(obj) { var arr = []; for (var key in obj) { arr.push(obj[key]); } arr.sort(function(a, b) { if (a.index > b.index) { return 1 } else if (a.index < b.index) { return -1 } else { return 0 } }) var result = {} arr.forEach((value, key) => result[key] = value) return result; } var result = sort_obj_by_index(obj) console.log(result)

Answer 2

    $json = '{
    "0": { "type": 12, "index": 115, "showType": 1, "achievementType": 0, "desc": "WING" },
    "4": { "type": 12, "index": 119, "showType": 1, "achievementType": 0, "desc": "WING" },
    "1": { "type": 12, "index": 116, "showType": 1, "achievementType": 0, "desc": "WING" },
    "3": { "type": 12, "index": 118, "showType": 1, "achievementType": 0, "desc": "WING" },
    "2": { "type": 12, "index": 117, "showType": 1, "achievementType": 0, "desc": "WING" }
}';

$obj = json_decode($json, true); // convert json to array
var_dump($obj); // print array before sorting
ksort($obj); // sorting
var_dump($obj); // print array after sorting

Answer 3

$filedata = file_get_contents('test.json');
$details = json_decode($filedata, true);
ksort($details);

Here 2 option

echo json_encode($details, 
JSON_UNESCAPED_UNICODE|JSON_UNESCAPED_SLASHES|JSON_FORCE_OBJECT);
// https://unminify.com/

OR

header('Content-type: text/javascript');
echo json_encode($details, JSON_PRETTY_PRINT);
