Parsing nested Values of AC list of Associative Arrays PHP

Issue

New to PHP, trying to parse the values of an associative array that is in a list in PHP.

I come from a Pythonic background and am faced with refactoring a code I wrote in Python to a PHP CLI Script. Working Pythonic Script - https://replit.com/@Terry-BrooksJr/AccesingDataAPI?v=1 (Note: To see Output CSV must edit in workspace)

Sample Payload

Having Trouble with Accessing the Nested Values in an Assoc. Array. - Seeing Note 4. IN PHP attempt

Here is the Function in Question: Python

def processSessions():
... Stuff to Open CVS File Pointer/Context Manager ... 
        for session in sessions['data']:
            for scoring in session['responses']:
                row_data = session['session_id'],scoring['question_reference'],scoring['question_type'],scoring['score'],scoring['max_score']
                csv_writer.writerow(row_data)

PHP Attempt

function processSessions()
{

    $sessionDataCSV = 'SessionData'. date("Y-m-d") .'.csv';
    $sessions = downloadSessions();
    //NOTE - 1. Marshal/Serializes JSON Session Data to PHP Data Structure (associative array) Using json_decode() method
    $associoatedSessionDataArray = $sessions;

    //NOTE - 2. Opens File pointer to CSV Output
    $csv_output_file_pointer = fopen($sessionDataCSV, 'w');

    //NOTE - 3. Writes field names
    $fieldNames = array(
                        "ID",
                        "Reference",
                        "Type",
                        "Score",
                        "MaxScore"
                        );
    echo($associoatedSessionDataArray['data']);
    fputcsv($csv_output_file_pointer, $fieldNames);
    if (is_array($associoatedSessionDataArray) || is_object($associoatedSessionDataArray))
    {
     // NOTE - 4. Loop to Write Records
        foreach ($associoatedSessionDataArray as $session) {
            foreach ($associoatedSessionDataArray as $scoring) 
            fputcsv($csv_output_file_pointer, [$session['session_id'],$scoring['question_reference'],$session['question_type'],$session['score'],$session['max_score']]);

        }
    }
    // }
    else // If $myList was not an array, then this block is executed. 
    {
  echo "Unfortunately, an error occured.";
    }

    //NOTE - 5. Closes File pointer to CSV Output
    fclose($csv_output_file_pointer);
}

Unexpected Output

ID,Reference,Type,Score,MaxScore
a9c92dc1-725c-456a-acc9-cdd32fd9f81b,,,6,8
ecc0bdb2-2fc9-4489-b2d6-b818a8b0ebc0,,,16,19
ee5ed0c3-f590-40d0-8480-8037914738ba,,,1,2

My Ask

• Explain Why the Script is NOT iterating thru the entire list of responses data['data']['responses'] (See Paste Bin link in #Sample Payload
• Why the output csv is NULL for the Reference,Type fields but parses and extracts the score and max_score when they are on the same level in terms of nesting.
