Mobi_Mtld_DA_ApiCached

This class significantly improves core DA PHP Api performance when used on a standard website with a single detection per request. Current optimizations consists of two main parts: 1) tree optimizer - speeds up loading the json file
2) cache provider - caches the results Typical usage:

 $ua = $_SERVER['HTTP_USER_AGENT'];

 $da_cache_provider = new Mobi_Mtld_DA_CacheProvider_FileCacheProvider();
 $da_api_cached = new Mobi_Mtld_DA_ApiCached("json/sample.json",
												$da_cache_provider);

 $properties = $da_api_cached->getProperties($ua);
 

Client side properties Client side properties can be collected and merged into the results by using the DeviceAtlas Javascript detection file. The results from the client side are sent to the server inside a cookie. The contents of this cookie can be passed to the DeviceAtlas getProperty and getProperties methods. The client side properties over-ride any data file properties and also serve as an input into additional logic to determine other properties such as the iPhone models that are otherwise not detectable. The following code shows how this can be done:

 $ua = $_SERVER['HTTP_USER_AGENT'];

 // Get the cookie containing the client side properties
 $cookie_contents = null;
 if (isset($_COOKIE['DAPROPS'])){
   $cookie_contents = $_COOKIE['DAPROPS'];
 }

 $da_cache_provider = new Mobi_Mtld_DA_CacheProvider_FileCacheProvider();
 $da_api_cached = new Mobi_Mtld_DA_ApiCached("json/sample.json",
												$da_cache_provider);

 $properties = $da_api_cached->getProperties($ua, $cookie_contents);
 

Note: It is not recommended to use ApiCached extension for batch processing (i.e. multiple User-Agent detections during a single request). In these situations use standard API interface. See Api.php for more information
