Here is my code:

<?php
require __DIR__.'/vendor/autoload.php';

use Kreait\Firebase\Factory;
use Kreait\Firebase\ServiceAccount;

$serviceAccount = ServiceAccount::fromJsonFile(__DIR__.'/google-service-account.json');
$firebase = (new Factory)
    ->withServiceAccount($serviceAccount)
    ->create();

$database = $firebase->getDatabase();

?>

Can you tell us the version of the firebase-php that you are currently using?

If you are using version lower than 5.x please update to the latest version.

https://github.com/kreait/firebase-php

It is using php 7.2^. Current wordpress requires 7.3 so it must be updated to latest version

Here is the documentation as well.

https://firebase-php.readthedocs.io/en/latest/

I don't know exactly what the problem is but it seems the error says you can't access a private method, so you should access it by updating it to public or public static method.

For ver 5.x

// @see https://firebase-php.readthedocs.io/en/5.2.0/troubleshooting.html
$factory = (new Factory)->withServiceAccount(__DIR__.'/google-service-account.json');

$database = $factory->createDatabase();

// if you want auth
//$auth = $factory->createAuth();
