ScientiaMobile WURFL Cloud Client for PHP

The WURFL Cloud Service by ScientiaMobile, Inc., is a cloud-based mobile device detection service that can quickly and accurately detect over 500 capabilities of visiting devices. It can differentiate between portable mobile devices, desktop devices, SmartTVs and any other types of devices that have a web browser.

This is the PHP Client for accessing the WURFL Cloud Service, and it requires a free or paid WURFL Cloud account from ScientiaMobile: http://www.scientiamobile.com/cloud

Installation

---

Requirements

• PHP 5.3+ (Some HTTP adapters may require 5.4+)
• json extension (almost always included)
• curl extension is recommended

Sign up for WURFL Cloud

First, you must go to http://www.scientiamobile.com/cloud and signup for a free or paid WURFL Cloud account (see above). When you've finished creating your account, and have selected the WURFL Capabilities that you would like to use, you must copy your API Key, as it will be needed in the Client.

Via Composer

composer require scientiamobile/wurflcloud

Via Source

Download the source code

require_once '/path/to/cloud/client/src/autoload.php'; 

Example WURFL Cloud Client

From your web browser, you should go to the WURFL Cloud Client's examples/ folder. You will see the Compatibility Test Script, which will verify that your configuration is compatible with the WURFL Cloud Client.

You should test your API Key from this page by pasting it in the input box, then clicking "Test API Key". If successful, you will see "Your server is able to access WURFL Cloud and your API Key was accepted." If there was a problem, the error message will be displayed instead. Please note that it may take a few minutes from the time that you signup for your WURFL Cloud API Key to become active.

Integration

You should review the included examples (example.php, MyWurfl.php, show_capabilities.php) to get a feel for the Client API, and how best to use it in your application.

Here's a quick example of how to get up and running quickly:

// Include the autoloader - edit this path! 
require_once '../src/autoload.php'; 
// Create a configuration object  
$config = new ScientiaMobile\WurflCloud\Config();  
// Set your WURFL Cloud API Key  
$config->api_key = 'xxxxxx:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';   
// Create the WURFL Cloud Client  
$client = new ScientiaMobile\WurflCloud\Client($config);  
// Detect your device  
$client->detectDevice();  
// Use the capabilities  
if ($client->getDeviceCapability('is_wireless_device')) {  
    echo "This is a mobile device";  
} else {  
    echo "This is a desktop device";  
}

Upgrading from v1.x

---

IMPORTANT: Since version 2.0.0, the WURFL Cloud Client for PHP uses namespaces. In addition, things were moved around a bit to allow for easier configuration.

To upgrade your existing v1 code, you will need to replace calls to the following classes:

old:
require_once '../Client/Client.php';
WurflCloud_Client_Config
WurflCloud_Client_Client
WurflCloud_Cache_Null
WurflCloud_Cache_Cookie

new:
require_once '../src/autoload.php';
ScientiaMobile\WurflCloud\Config
ScientiaMobile\WurflCloud\Client
ScientiaMobile\WurflCloud\Cache\NullCache
ScientiaMobile\WurflCloud\Cache\Cookie

Every other class was also renamed/namespaced, so if you are using them directly, you can follow the mapping above to figure out the new name.

If you were using the MyWurfl.php singleton, you can use the new one and no code changes will be required in your application.

Note that in v2, support for proxy servers was added as well as better support for timeouts. More on these options is found below.

Configuration

---

The WURFL Cloud Client object ScientiaMobile\WurflCloud\Client takes three arguments: Config, Cache, HttpClient.

Config

ScientiaMobile\WurflCloud\Config
Used for setting the WURFL Cloud API Key api_key and adding addCloudServer() / removing clearServers() WURFL Cloud Servers.

Cache (optional)

Caching classes:

• ScientiaMobile\WurflCloud\Cache\NullCache: Disables caching completely
• ScientiaMobile\WurflCloud\Cache\Cookie: Cookie-based caching
• ScientiaMobile\WurflCloud\Cache\File: Filesystem-based caching
• ScientiaMobile\WurflCloud\Cache\APC: APC (or APCu) memory-based caching
• ScientiaMobile\WurflCloud\Cache\Memcache: Memcached distributed memory-based caching using the PHP memcache extension
• ScientiaMobile\WurflCloud\Cache\Memcached: Memcached distributed memory-based caching using the PHP memcached extension

HttpClient (optional)

• ScientiaMobile\WurflCloud\HttpClient\Fsock: Uses native PHP fsock calls
• ScientiaMobile\WurflCloud\HttpClient\FileGetContents: Uses native PHP file_get_contents calls
• ScientiaMobile\WurflCloud\HttpClient\Curl: Uses the PHP extension curl
• ScientiaMobile\WurflCloud\HttpClient\Guzzle: Uses the Guzzle HTTP client (version < 4)
• ScientiaMobile\WurflCloud\HttpClient\GuzzleHttp: Uses the Guzzle HTTP client (version 6+)

Note: to use Guzzle or GuzzleHttp, you must have the Guzzle library loaded. To load it locally, you can run the following command from the root of the WURFL Cloud Client folder:

composer update

Then make sure to use the composer autoloader vendor/autoload.php instead of the built in one (src/sutoload.php).

Proxy Server Configuration

The FileGetContents, Curl, Guzzle and GuzzleHttp HTTP Clients support a proxy server configuration via the setProxy() method:

// Common proxy examples
$http_client = new ScientiaMobile\WurflCloud\HttpClient\Curl();
 
// Socks 4 Proxy
$http_client->setProxy("socks4://192.168.1.1:1080");

// Socks 4a Proxy
$http_client->setProxy("socks4a://192.168.1.1:1080");

// Socks 5 Proxy
$http_client->setProxy("socks5://192.168.1.1:1080");

// Socks 5 Proxy + Authentication
$http_client->setProxy("socks5://someuser:[email protected]:1080");

// HTTP Proxy
$http_client->setProxy("http://192.168.1.1:8080");

// HTTP Proxy + Authentication
$http_client->setProxy("http://someuser:[email protected]:8080");

// Pass $http_client in to the Client to use it
$client = new ScientiaMobile\WurflCloud\Client($config, $cache, $http_client);

HTTP Timeout

The WURFL Cloud Client is set to forcefully terminate the WURFL Cloud request after 1 second if a response has not been received. In some cases you may want to increase this timeout to account for high latency. All of the HTTP Clients support the setTimeout() method:

$http_client = new ScientiaMobile\WurflCloud\HttpClient\Curl();

// Timeout is in milliseconds (10000 == 10 seconds)
$http_client->setTimeout(10000);

// Pass $http_client in to the Client to use it
$client = new ScientiaMobile\WurflCloud\Client($config, $cache, $http_client);

Google App Engine

---

In order to use the WURFL Cloud Client in a Google App Engine PHP application, you may need to make some changes to the default configuration.

First, you should use the FileGetContents HTTP Client since curl and fsock are not supported by default.

$http_client = new ScientiaMobile\WurflCloud\HttpClient\FileGetContents();

Next, you should use either Memcache or File for caching:

Memcache:

$cache = new ScientiaMobile\WurflCloud\Cache\Memcache();

File:

$cache = new ScientiaMobile\WurflCloud\Cache\File();

// Disable UNIX hard links since they aren't supported in Google App Engine
$cache->use_links = false;

// Update this to point to your Google Cloud Storage bucket
$cache->cache_dir = "gs://bucket_name/";

Putting this all together, the following is a fully functional Google App Engine config (using Memcache):

// Create a configuration object
$config = new ScientiaMobile\WurflCloud\Config();

// Set your WURFL Cloud API Key
$config->api_key = 'xxxxxx:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';

// Create the cache adapter
$cache = new ScientiaMobile\WurflCloud\Cache\Memcache();

// Create the HttpClient adapter
$http_client = new ScientiaMobile\WurflCloud\HttpClient\FileGetContents();

// Create the WURFL Cloud Client
$client = new ScientiaMobile\WurflCloud\Client($config, $cache, $http_client);

// Detect device
$client->detectDevice();

Unit Testing

Unit tests are included with the client and can be run with PHPUnit. Before you can run the unit tests, you must install the dependencies via Composer from the root directory:

cd WurflCloudClient-PHP*
curl -sS https://getcomposer.org/installer | php
php composer.phar install

Before you run the PHPUnit tests, you must set your WURFL Cloud API Key in an environment variable so it can be used in the tests. To run the tests, run phpunit from the root directory (where phpunit.xml.dist is located):

export WURFL_CLOUD_API_KEY="123456:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
php vendor/bin/phpunit -v

You can also use the Docker image included in tests/docker to run the test suite as follows:

cd tests/docker
export WURFL_CLOUD_API_KEY="123456:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
docker-compose up

Note that in order to get all the tests to pass, you will need to use the API Key from a Premium WURFL Cloud account with all capabilities enabled. This is because small responses from the WURFL Cloud system are never compressed if they fit within one network packet, and the unit tests that cover compression see this as a failure. If this is the case, you will see failures like this:

There were 3 failures:

1) ScientiaMobile\WurflCloud\HttpClient\CurlTest::testCallCompression
Failed asserting that an array contains 'Content-Encoding: gzip'.

2) ScientiaMobile\WurflCloud\HttpClient\FsockTest::testCallCompression
Failed asserting that an array contains 'Content-Encoding: gzip'.

3) ScientiaMobile\WurflCloud\HttpClient\GuzzleTest::testCallCompression
Failed asserting that an array contains 'Content-Encoding: gzip'.

You will also need to have the extensions apc, memcache, memcached, json, and curl enabled. By default, apc is not enabled in CLI mode, so you may need to launch phpunit like this to force it on:

php -d apc.enable_cli=1 vendor/phpunit/phpunit/phpunit.php -v
