How can I populate another class function using PHP/Json object - php

Question

so I have this JSON object, which I have converted into a PHP object, for example I can use $apiobject->Response->DataItems and get a response.
This is stored in a class called returnjsonObject with a public function called getJsonObject.
In the same file how can I populate another class using the data from this $apiobject into something like:
class Response
{
public $StatusCode;
}
Then how can I for example echo out $StatusCode
Here is part of my file:
class Response
{
public $StatusCode; //*I want this to equal $apiobject->Response->DataItems*
}
class returnjsonObject{
public function getJsonObject()
{
echo"<pre>";
$apiobject = json_decode($response);
var_dump($apiobject->Response->DataItems);
echo"<pre>";
}
I've heard of using $this but I have to admit I don't understand it.
tl;dr I need to use $apiobject to populate $StatusCode using $apiobject->Response->DataItems
Hope you understand my question :-)

Answer 1

You can use setter and getter
class Response{
public $StatusCode;
/**
......
*/
public function __construct($attributes = Array()){
// Apply provided attribute values
foreach($attributes as $field=>$value){
$this->$field = $value;
}
}
function __set($name,$value){
if(method_exists($this, $name)){
$this->$name($value);
}
else{
// Getter/Setter not defined so set as property of object
$this->$name = $value;
}
}
function __get($name){
if(method_exists($this, $name)){
return $this->$name();
}
elseif(property_exists($this,$name)){
return $this->$name;
}
return null;
}
}
$DataItems =$apiobject->DataItems;
$response = new Response($DataItems);
echo $response->StatusCode;
Code not tested though. Learn more here.

Answer 2

I would first set all attributes in Response Class from $apiobject like this
<?php
class Response {
public $StatusCode;
/* more attributes
...
*/
public $Name
} //end of Response class
Then instantiate Response class and set attributes
$response = new Response();
$response->StatusCode =$apiobject->DataItems->StatusCode;
$response->Name=$apiobject->DataItems->Name;
/* Set all other properties
.......
*/
echo $respose->StatusCode; //output status code
Note: you use $this to make reference to a function or a property in the current class. i.e
Class Example {
public $name;
public function getThatName(){
return $this->name; //we make reference to property `$name`
}
}
$this can only be use in a Class or Object to reference a property or a function in itself.
You can not do this.
$example = new Example();
$this->name; //Wrong because you are not in `Example` class
