This is a schema generator that displays the key:value pair

 "default": [
                    "one": "u0001u0000u0000u0000",
                    "two": "u0002u0000u0000u0000",
                    "three": "u0003u0000u0000u0000"

What I would like to print out is "default": [{"u0001u0000u0000u0000u0002u0000u0000u0000u0003u0000u0000u0000"}]

Similarly if it is an object for instance:

"default": [ "a":
                    "one": "u0001u0000u0000u0000",
                    "two": "u0002u0000u0000u0000",
                    "three": "u0003u0000u0000u0000"

concatenate only values and print like this:

["a": {"u0001u0000u0000u0000u0002u0000u0000u0000u0003u0000u0000u0000"}]

Sample Code Test: // this method gets the value entered by user in json format. The user can put in a nested json format as well. The above examples that I mentioned works. it then calls for scanForNestedType method which scans whether the format contains any array, array>, map etc... Once it scans for nested type, it internally calls $this->encodeValues($unit)which converts the values entered by user from integer to bytes.

Here is an example:

User enters array [{"one": 1, "two": 2, "three": 3}]. After conversion, the result would be as follows: [ { "one": u0001u0000u0000u0000, "two": u00002u0000u0000u0000, "three: u0003u0000u0000u0000 } ]

Now I am getting the values correctly for each key. All I need is to print in this format: [ { u0001u0000u0000u0000u0002u0000u0000u0000u0003u0000u0000u0000 } ]

private function jsonDecode(array $value)
    $strValue = $value['value'];
    $jsonValue = json_decode($strValue);

    return $jsonValue;

private function scanForNestedType(&$value)
    foreach ($value as $key => &$unit) {
        if (is_array($unit) || is_object($unit)) {
        } else {
            $value->$key = $this->encodeValues($unit);

private function encodeValues(int $value)
    $encodedValue = '';

    $bytesArray = unpack("C*", pack("V", $value));
    foreach ($bytesArray as $byte) {
        $encodedValue .= sprintf('u%04x', dechex($byte));
    return $encodedValue;

If I get a working example then it would be great!

    You can use json_decode to convert json to an array. Then implode sub-array ['one'....] using foreach loop.


    $json1 = '[{"one": "u0001u0000u0000u0000", "two": "u0002u0000u0000u0000", "three": "u0003u0000u0000u0000"}]';
    $json2 = '[{ "a": { "one": "u0001u0000u0000u0000", "two": "u0002u0000u0000u0000", "three": "u0003u0000u0000u0000" } }]';
    $arr1 = json_decode($json1,true);
    $arr2 = json_decode($json2,true);
    foreach($arr1 as $data){
        $default1[] = implode($data);
    $default1 = json_encode($default1, JSON_FORCE_OBJECT);
    foreach($arr2 as $key => $child){
        foreach($child as $childKey => $data){
            $default2[$childKey] = implode($data);
    $default2 = json_encode($default2, JSON_FORCE_OBJECT);



    Live Demo

    You can now json_decode $default1, $default2 to get php object/array.
