Array can filter ?

[yljphp]

    `$articles = array (
        array ( 'id' => 1, 'title' => 'Article 1', ),
        array ( 'id' => 2, 'title' => 'Article 2', ),
    );

    $filter = DataFilter::source ( $articles );

    $filter->add ( 'id', 'ID', 'text' );
    $filter->add ( 'title', 'Title', 'text' );
    $filter->submit ( '搜索' );
    $filter->reset ( '重置' );
    $filter->build ();
    $grid = DataGrid::source($filter);
    $grid->add('id','ID', true);
    $grid->add('title','Title', true);
    $grid->paginate ( 1 );`
