[FIXED] Fatal error: Uncaught Error: Call to undefined method Kreait\Firebase\Factory::getDatabase()

Issue

I'm trying to use php with firebase, but I have this error when I'm trying to run the code.

Fatal error: Uncaught Error: Call to undefined method Kreait\Firebase\Factory::getDatabase() in C:\xampp\htdocs\table\includes\db.php on line 10

the db.php file:

<?php

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

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

$firebase = (new Factory())->withServiceAccount(__DIR__.'/bib-bayitback-firebase-adminsdk-lkch9-44e22401ec.json');

$database = $firebase->getDatabase();



?>

my composer.json file:

{
    "require": {
        "kreait/firebase-php": "5.0"
    }
}

how can I solve it?

Solution

You have installed v5.0.0 of the Firebase Admin SDK for PHP, but the tutorial you followed is for a 4.x version.

This is an issue that happens so often that it has its own section in the "Troubleshooting" section in the SDK's documentation.

With v5.x, the correct way to initialize a Firebase component is:

$factory = (new Factory())->withServiceAccount(__DIR__.'/bib-bayitback-firebase-adminsdk-lkch9-44e22401ec.json');

$database = $factory->createDatabase();

As a side note:

{
    "require": {
        "kreait/firebase-php": "5.0"
    }
}

will install version 5.0 and 5.0. only (the current version is 5.13). You will never receive a newer release of the library because you fixed the version constraint to 5.0.

If you want to be sure to receive new features and bug fixes for the SDK, please add a caret(^) in front of the version number:

{
    "require": {
        "kreait/firebase-php": "^5.0"
    }
}

This will allow your project to receive the latest 5.x release of the SDK.
