PHP Piwik_DataTable::loadFromSimpleArray方法代碼示例

 /**
  * This method post processes the data resulting from the API call.
  * 
  * - If the data resulted from the API call is a Piwik_DataTable then 
  * 		- we apply the standard filters if the parameters have been found
  * 		  in the URL. For example to offset,limit the Table you can add the following parameters to any API
  *  	  call that returns a DataTable: filter_limit=10&filter_offset=20
  * 		- we apply the filters that have been previously queued on the DataTable
  *        @see Piwik_DataTable::queueFilter()
  * 		- we apply the renderer that generate the DataTable in a given format (XML, PHP, HTML, JSON, etc.) 
  * 		  the format can be changed using the 'format' parameter in the request.
  *        Example: format=xml
  * 
  * - If there is nothing returned (void) we display a standard success message
  * 
  * - If there is a PHP array returned, we try to convert it to a dataTable 
  *   It is then possible to convert this datatable to any requested format (xml/etc)
  * 
  * - If a bool is returned we convert to a string (true is displayed as 'true' false as 'false')
  * 
  * - If an integer / float is returned, we simply return it
  * 
  * @throws Exception If an object/resource is returned, if any of conversion fails, etc. 
  * 
  * @param mixed The initial returned value, before post process
  * @return mixed Usually a string, but can still be a PHP data structure if the format requested is 'original'
