<?php
include_once "FirebaseToken.php";
require_once 'firebaseLib.php';

$secret = "dHQkvze--"; //FIREBASE SECRET
$tokenGen = new Services_FirebaseTokenGenerator($secret);
$token = $tokenGen -> createToken(array("app_user_id" => 1234, "isAdmin" => true));

$url = 'https://x.firebaseio.com/';

$fb = new fireBase($url, $token);

$response = $fb -> get('/debugNode/');
//echo $response;  //using firebaseLib by default is json, no need to use 'REST API' .json

$jsonArray = json_decode($response);

$tmp = "";
foreach ($jsonArray as $value) {
	$debugChildNode = $value; //node
	
	$tmp .= $debugChildNode -> Comment . "<br>"; //field
}

echo $tmp;

the rule :

       "debugNode": { 
                   ".read": "auth.isAdmin == true",
