PHP Supported Versions

• PHP >= 5.3.2

Getting Started

Download a release archive from wurfl site and extract it to a directory suitable for your application.

To start using the API you need to set some configuration options.

IMPORTANT: The WURFL API is closely tied to the WURFL.XML file. New versions of the WURFL.XML are compatible with old versions of the API by nature, but the reverse is NOT true. Old versions of the WURFL.XML are NOT guarenteed to be compatible with new versions of the API. Let's restate that: This API is NOT compatible with old versions of the WURFL.XML. The oldest copy of WURFL that can be used with this API is included in this distribution.

For the impatient ones

Please look at the sample of the configuration files in examples/demo/ directory.

$wurflDir = dirname(__FILE__) . '/../../../WURFL';
$resourcesDir = dirname(__FILE__) . '/../../resources';

require_once $wurflDir.'/Application.php';

$persistenceDir = $resourcesDir.'/storage/persistence';
$cacheDir = $resourcesDir.'/storage/cache';

// Create WURFL Configuration
$wurflConfig = new WURFL_Configuration_InMemoryConfig();

// Set location of the WURFL File
$wurflConfig->wurflFile($resourcesDir.'/wurfl.zip');

// Set the match mode for the API ('performance' or 'accuracy')
$wurflConfig->matchMode('performance');

// Setup WURFL Persistence
$wurflConfig->persistence('file', array('dir' => $persistenceDir));

// Setup Caching
$wurflConfig->cache('file', array('dir' => $cacheDir, 'expiration' => 36000));

// Create a WURFL Manager Factory from the WURFL Configuration
$wurflManagerFactory = new WURFL_WURFLManagerFactory($wurflConfig);

// Create a WURFL Manager
/* @var $wurflManager WURFL_WURFLManager */
$wurflManager = $wurflManagerFactory->create();

Now you can use some of the WURFL_WURFLManager class methods;

$device = $wurflManager->getDeviceForHttpRequest($_SERVER);
$device->getCapability("is_wireless_device");
$device->getVirtualCapability("is_smartphone");

Create a configuration object

1. Set the paths to the location of the main WURFL file (you can use zip files if you have the zip extension enabled)

2. Configure the Persistence provider by specifying the provider and the extra parameters needed to initialize the provider. The API supports the following mechanisms:

   • Memcache (http://uk2.php.net/memcache)
   • APC (Alternative PHP Cache http://www.php.net/apc)
   • MySQL
   • Memory
   • File

3. Configure the Cache provider by specifying the provider and the extra parameters needed to initialize the provider. The API supports the following caching mechanisms:

   • Memcache (http://uk2.php.net/memcache)
   • APC (Alternative PHP Cache http://www.php.net/apc)
   • File
   • Null (no caching)

Example Configuration

// Create WURFL Configuration
$wurflConfig = new WURFL_Configuration_InMemoryConfig();
// Set location of the WURFL File
$wurflConfig->wurflFile($resourcesDir.'/wurfl.zip');
// Set the match mode for the API ('performance' or 'accuracy')
$wurflConfig->matchMode('performance');
// Setup WURFL Persistence
$wurflConfig->persistence('file', array('dir' => $persistenceDir));
// Setup Caching
$wurflConfig->cache('file', array('dir' => $cacheDir, 'expiration' => 36000));

Using the WURFL PHP API

Getting the device

You have four methods for retrieving a device:

1. getDeviceForRequest(WURFL_Request_GenericRequest $request) where a WURFL_Request_GenericRequest is an object which encapsulates userAgent, ua-profile, support for xhtml of the device.

2. getDeviceForHttpRequest($_SERVER) Most of the time you will use this method, and the API will create the WURFL_Request_GenericRequest object for you.

3. getDeviceForUserAgent(string $userAgent) Used to query the API for a given userAgent string.

4. getDevice(string $deviceID) Gets the device by its device ID (ex: apple_iphone_ver1).

Usage example:

$device = $wurflManager->getDeviceForHttpRequest($_SERVER);

Getting the device properties and its capabilities

The properties Device ID and Fall Back Device ID are properties of the device:

$deviceID = $device->id;
$fallBack = $device->fallBack;

To get the value of a capability, use getCapability():

$value = $device->getCapability("is_tablet");
$allCaps = $device->getAllCapabilities();

To get the value of a virtual capability, use getVirtualCapability():

$value = $device->getVirtualCapability("is_smartphone");
$allVCaps = $device->getAllVirtualCapabilities();

Useful Methods

The root WURFL device object has some useful functions:

/* @var $device WURFL_CustomDevice */
$device = $wurflManager->getDeviceForHttpRequest($_SERVER);

/* @var $root WURFL_Xml_ModelDevice */
$root = $device->getRootDevice();

$group_names = $root->getGroupNames();
$cap_names = $root->getCapNames();
$defined = $root->isCapabilityDefined("foobar");

WURFL Reloader

WURFL can update the persistence data automatically without any configuration by checking the modification time of the WURFL file. To enable, set allow-reload to true in the config:

$wurflConfig->allowReload(true);
