WURFL (Wireless Universal Resource File) is a database of mobile device capabilities. This class provides a features adapter that utilizes the WURFL PHP API in order to discover mobile device capabilities to inject into UserAgent device instances. Please see the Zend_Http_UserAgent quick start for an example. wurflapi.wurfl_api_version If using the WURFL API, use this key to specify which version you are using; typically, this will be either "1.0" or "1.1". wurflapi.wurfl_lib_dir If using the WURFL API, use this key to specify in which directory the library exists. wurflapi.wurfl_config_file If using the WURFL API, use this key to specify the location of the configuration file you will use; typically, this will be resources/wurfl-config.php within the wurfl_lib_dir. wurflapi.wurfl_config_array.wurfl.main-file If using version 1.1 of the WURFL API, you can omit using a wurfl_config_file, and instead provide an associative array of configuration values. This particular value indicates the location of the wurfl.xml file containing the actual WURFL database. wurflapi.wurfl_config_array.wurfl.patches[] If using version 1.1 of the WURFL API, you can omit using a wurfl_config_file, and instead provide an associative array of configuration values. This particular value is an array of file locations containing patchfiles for the wurfl.main-file (which are used to ammend and extend the primary database file). wurflapi.wurfl_config_array.persistence.provider If using version 1.1 of the WURFL API, you can omit using a wurfl_config_file, and instead provide an associative array of configuration values. This particular value indicates the type of persistence provider used when caching discovered capabilities. See the WURFL documentation for potential values; "file" is a known good value. wurflapi.wurfl_config_array.persistence.dir If using version 1.1 of the WURFL API, you can omit using a wurfl_config_file, and instead provide an associative array of configuration values. This particular value indicates the location where the persistence provider will cache discovered capabilities. getFromRequest array $request, array $config Decompose the request in order to return an array of device capabilities.
