    $sp = new SplitWord(); 

    $titleindexs = explode(" ",trim($sp->GetIndexText($sp->SplitRMM($title)))); 

    //$allindexs = explode(" ",trim($sp->GetIndexText($sp->SplitRMM(Html2Text($body)),200))); 

    if(/*is_array($allindexs) && */is_array($titleindexs)){ 

        foreach($titleindexs as $k){ 

            if(strlen($tag)>=50) break; 

            else $tag .= $k." "; 

        } 

        /*foreach($allindexs as $k){ 

            if(strlen($keywords)>=50) break; 

            else if(!in_array($k,$titleindexs)) $keywords .= $k." "; 

     }*/ 

    } 

    $sp->Clear(); 

    unset($sp); 

    //$tag = preg_replace("/
