php - Getting an error when trying to pull categories from a JSON

Question

i tried to pull the categories in Json but couldn't succeed. i was able to get other fields easily. i tried several foreach intertwined but failed.

JSON example

{
  "MainUnit": "1",
        "ProductCategory": {
            "ID": 160,
            "Name": "Basketball",
            "MainCategory": false,
            "ParentCategoryID": 152,
            "ParentCategory": {
                "ID": 152,
                "Name": "Football",
                "MainCategory": false,
                "ParentCategoryID": 2,
                "ParentCategory": {
                    "ID": 2,
                    "Name": "SPORT",
                    "MainCategory": true,
                    "ParentCategory": null,
                    "ParentCategoryID": 0
                }
            }
            "Brand": "Spect"
        },
    }
    ....

json outputs come in order like this...

$curl = curl_init();
curl_setopt_array($curl, array(
  CURLOPT_URL => 'http://example.com/json/sports',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'GET',
  CURLOPT_HTTPHEADER => array(
    'Content-Type: application/json',
    'Accept: application/json',
    'Authorization: Bearer gd6yaw7gjiLQ8VeytrpLrl9mzU0oUx4966D61PdbuYVrCU178E'
  ),
));
$response = curl_exec($curl);
curl_close($curl);

$response = json_decode($response);
foreach($response as $return){
    foreach($return->ProductCategory as $categories){
            if ($categories != null) {
                echo $categories->ID.'<br />';
                echo $categories->Name.'<br />';
            }
            foreach($categories->ParentCategory as $categorie){
                if ($categorie->parentCategory != null) {
                    echo $categorie->ID.'<br />';
                    echo $categorie->Name.'<br />';
                    echo $categorie->MainCategory.'<br />';
                    echo $categorie->ParentCategoryID.'<br />';
                }else{
                    echo $categorie->ID.'<br />';
                    echo $categorie->Name.'<br />';
                    echo $categorie->MainCategory.'<br />';
                    echo $categorie->ParentCategoryID.'<br />';
                }
                foreach($categorie->ParentCategory as $category){
                    if ($category->parentCategory != null) {
                        echo $category->ID.'<br />';
                        echo $category->Name.'<br />';
                        echo $category->MainCategory.'<br />';
                        echo $category->ParentCategoryID.'<br />';
                    }else{
                        echo $category->ID.'<br />';
                        echo $category->Name.'<br />';
                        echo $category->MainCategory.'<br />';
                        echo $category->ParentCategoryID.'<br />';
                    }
                }
            }
        }
}

I pull the json data with the curl method as above, and solve it with json_decode. How can I pull categories in a healthy way?
