Вот код:

if ($preview) { 
        $out = '<img src="preview.php?type=1&amp;img=' . urlencode($preview) . '" alt="preview" />'; 
    } 
    $out .= '<img src="' . $filesroot . '/images/' . (file_exists($filesroot . '/images/' . $format_file . '.png') ? $format_file . '.png' : 'file.gif') . '" alt="file" /> '; 
    $out .= '<a href="?act=view&amp;id=' . $res_down['id'] . '">' . checkout($res_down['rus_name']) . '</a> (' . $res_down['field'] . ')'; 
   if ($rights == 4 || $rights > 6) { 
   $out .= '(<a href="index.php?act=rename&amp;id=' . $res_down['id'] . '">R</a>)';} 
    if (is_file('about/' . $res_down['id'] . '.txt')) { 
        $about = file_get_contents('about/' . $res_down['id'] . '.txt'); 
        if (mb_strlen($about) > 100) 
            $about = mb_substr($about, 0, 90) . '...'; 
        $out .= '<div class="sub">' . checkout($about, 2) . '</div>'; 
    } 
    $out .= '<div class="sub"><a href="index.php?act=comms&amp;id=' . $res_down['id'] . '">Комментарии</a> (' . $res_down['total'] . ')</div>'; 
    return $out; 
}

if ($rights == 4 || $rights > 6) { 
   $out .= '(<a href="index.php?act=rename&amp;id=' . $res_down['id'] . '">R</a>)';}
