I used composer to install firebase admin-sdk with command composer require kreait/firebase-php The resulting downloaded folder structure had

vendor/kreait/firebase-php , vendor/kreait/clock, vendor/kreait/firebase-tokens.

When I ran composer show kreait/firebase-php it did not list firebase-php under the require section. Instead kreait/firebase-tokens and kreait/clock was listed. the version for admin-sdk is 5.26.5. The vendor folder is in the root of my project folder. I added a test.php file with the following code.

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

if (class_exists('Kreait\Firebase\Firebase')) {
    echo "Firebase class found!";
    $firebase = new \Kreait\Firebase\Firebase(); // Or your Firebase initialization code
} else {
    echo "Firebase class NOT found!";
} 

It outputs class not found. Output for php -v is

PHP 8.3.14 (cli) (built: Nov 19 2024 15:53:36) (NTS Visual C++ 2019 x64)

I next tried composer clear-cache composer install. Still it cannot find the sdk location when i run the test.php. There is something wrong with whatever being downloaded by the composer. The folder structure is not the way it should be. Please advise.

• php
• firebase-cloud-messaging
• google-admin-sdk

• 2 Ensure the correct class is being referenced. use Kreait\Firebase\Factory to initialize Firebase. Modify your code like this: require __DIR__ . '/vendor/autoload.php';`` use Kreait\Firebase\Factory;`` $firebase = (new Factory)->create(); echo "Firebase initialized!"; check that the composer.json file lists the package correctly and try clearing the Composer cache – Kamyar Safari Commented Feb 3 at 6:43
• 1 Thank you. This was the correct way. A new Factory() instance was to be created and not a new firebase() like I was doing. I cannot mark your comment as the accepted answer. If you have the time please post it as answer. – adbury Commented Feb 14 at 23:33

Ensure the correct class is being referenced. use Kreait\Firebase\Factory to initialize Firebase. Modify your code like this:

require __DIR__ . '/vendor/autoload.php';
use Kreait\Firebase\Factory;
$firebase = (new Factory)->create();
echo "Firebase initialized!";

check that the composer.json file lists the package correctly and try clearing the Composer cache
