The code you posted is from kreait/firebase-php and shows a private method from the
ServiceAccount class that can not be called directly since release 5.0 of the SDK.
Straight from the troubleshooting section in the documentation:
You probably followed a tutorial article or video targeted at a 4.x version, and your code looks like this:
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();
Change it to the following:
use Kreait\Firebase\Factory; $factory = (new Factory)->withServiceAccount(__DIR__.'/google-service-account.json'); $database = $factory->createDatabase();
