firebase-php

Firebase php wrapper for REST API

##Prerequisites

• PHP >= 5.5
• Firebase >= 1.1.1
• Composer (recommended, not required)

Installation using composer (recommended)

Set your projects minimum stability to dev in composer.json. This is caused by the PHP-JWT dependency. After updating the composer.json file, simply execute: composer require eelkevdbos/firebase-php dev-master

##Installation without composer For a vanilla install, the following dependencies should be downloaded:

• firebase/php-jwt github
• guzzlehttp/guzzle github

Loading the dependencies can be achieved by using any PSR-4 autoloader.

Basic Usage

By setting your firebase secret as token, you gain superuser access to firebase.

use Firebase\Firebase;

$fb = Firebase::initialize(YOUR_FIREBASE_URL, YOUR_FIREBASE_SECRET);

//or set your own implementation of the ClientInterface as second parameter of the regular constructor
$fb = new Firebase([ 'base_url' => YOUR_FIREBASE_BASE_URL, 'token' => YOUR_FIREBASE_SECRET ], new GuzzleHttp\Client());

//retrieve a node
$nodeGetContent = $fb->get('/node/path');

//set the content of a node
$nodeSetContent = $fb->set('/node/path', array('data' => 'toset'));

//update the content of a node
$nodeUpdateContent = $fb->update('/node/path', array('data' => 'toupdate'));

//delete a node
$nodeDeleteContent = $fb->delete('/node/path');

//push a new item to a node
$nodePushContent = $fb->push('/node/path', array('name' => 'item on list'));

Advanced Usage

For more finegrained authentication, have a look at the security rules. Using the token generator allows you to make use of the authentication services supplied by Firebase.

use Firebase\Firebase;
use Firebase\Auth\TokenGenerator;

$tokenGenerator = new TokenGenerator(YOUR_FIREBASE_SECRET);

$token = $tokenGenerator->generateToken(['email' => '[email protected]'])

$fb = Firebase::initialize(YOUR_FIREBASE_BASE_URL, $token);

The above snippet of php interacts with the following security rules:

{
  "rules": {
    ".read": "auth.email == '[email protected]'"
    ".write": "auth.email == '[email protected]'"
  }
}

And will allow the snippet read-access to all of the nodes, but not write-access.

##Concurrent requests Execution of concurrent requests can be achieved with the same syntax as regular requests. Simply wrap them in a Closure and call the closure via the batch method and you are all set.

use Firebase\Firebase;

$fb = Firebase::initialize(YOUR_FIREBASE_BASE_URL, YOUR_FIREBASE_SECRET);

$requests = $fb->batch(function ($client) {
    for($i = 0; $i < 100; $i++) {
        $client->push('list', $i);
    }
});

$pool = new GuzzleHttp\Pool($fb->getClient(), $requests);
$pool->wait();

Integration

At the moment of writing, integration for Laravel 4.* is supported. A service provider and a facade class are supplied. Installation is done in 2 simple steps after the general installation steps:

1. edit app/config/app.php to add the service provider and the facade class

    'providers' => array(
      ...
      'Firebase\Integration\Laravel\FirebaseServiceProvider'
    )
    
    'aliases' => array(
      ...
      'Firebase' => 'Firebase\Integration\Laravel\Firebase'
    )

2. edit app/config/services.php (supplied by default from L4.2) to add token and base_url settings

    'firebase' => array(
      'base_url' => YOUR_FIREBASE_BASE_URL,
      'token' => YOUR_FIREBASE_SECRET
    )

##Eventing

The library supports the EventEmitter pattern. The event-emitter is attached to the Firebase class. Events currently available:
