        }
        $value = strtr($value, get_html_translation_table(HTML_ENTITIES));    // mask the content

            if($key == $searchkey) {
                $str = $value;    // just return the value
            }
        } else {    // all meta tags
            $pattern = '/ |,/i';    // ' ' or ','
            $array = preg_split($pattern, $value, -1, PREG_SPLIT_NO_EMPTY);    // split it in an array, so we have the count of words           
            $str .= '
' . $key . ' (' . count($array) . ' words | ' . strlen($value) . ' chars)' . $value . '
