// some filter (must be an instance of Zend_Filter_Interface!)
// - The package comes with HtmlEntitiesFilter and Nl2BrFilter
// - also possible: chaining multiple filters:
//$filter = new OutputFilterChain();
//$filter->pushFilter(new HtmlEntitiesFilter())
// ->pushFilter(new Nl2BrFilter());
$filter = new HtmlEntitiesFilter();

$wrapper = new OutputFilterWrapper($filter);

// black magic!
$wrapper->wrap($data);

// demonstration, execute this file to see how it works!
