destoon自动生成tag插件

1、打开api\extend.func.php
搜索：
?>
在上面增加：
//S 自动生成tag
function substrin($str, $lenth, $start=0)
{
    $len = strlen($str);
    $r = array();
    $n = 0;
    $m = 0;

    for($i=0;$i<$len;$i++){
        $x = subst($str, $i, 1);
        $a = base_convert(or($x), 10, 2);
        $a = subst( ‘00000000 ‘.$a, -8);

        if ($n < $start){
            if (subst($a, 0, 1) == 0) {
            }
            else if (subst($a, 0, 3) == 110) {
              $i += 1;
            }
            else if (subst($a, 0, 4) == 1110) {
              $i += 2;
            }
            $n++;
        }
        else{
            if (subst($a, 0, 1) == 0) {
                 $r[] = subst($str, $i, 1);
            }else if (subst($a, 0, 3) == 110) {
                 $r[] = subst($str, $i, 2);
                $i += 1;
            }else if (subst($a, 0, 4) == 1110) {
                $r[] = subst($str, $i, 3);
                 $i += 2;
            }else{
                 $r[] = ‘ ‘;
            }
            if (++$m >= $lenth){
              break;
            }
        }
    }
    return join(‘‘,$r);
}
function convert_encoding($str,$nfate,$ofate){
    if ($ofate==”UTF-8″){ return $str; }
    if ($ofate==”GB2312″){ $ofate=”GBK”; }
    if(function_exists(“mb_convert_encoding”)){
        $str=mb_convert_encoding($str,$nfate,$ofate);
    }
    else{
        $ofate.=”//IGNORE”;
        $str=iconv( $nfate , $ofate ,$str);
    }
    return $str;
}
function getpage($url,$charset)
{
    $charset = strtoupper($charset);
    $content = “”;
    if(!empty($url)) {
        if( function_exists(‘curl_init‘) ){
            $ch = @curl_init();
            curl_setopt($ch, CURLOPT_URL, $url);
            curl_setopt($ch, CURLOPT_USERAGENT, ‘Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; )‘);
            curl_setopt($ch, CURLOPT_HEADER, 0);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt($ch, CURLOPT_cookie, ‘domain=www.baidu.com‘);
            curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 120);
            curl_setopt($ch, CURLOPT_TIMEOUT, 30);
            $content = @curl_exec($ch);
            curl_close($ch);
        }
        else if( ini_get(‘allow_url_fopen‘)==1 ){
            $content = @file_get_contents($url);
        }
        else{
            die(‘当前环境不支持采集【curl 或 allow_url_fopen】，请检查php.ini配置；‘);
        }
        $content = convert_encoding($content,”utf-8″,$charset);
    }
    return $content;
}
function gettag($title,$content){
    $data = getpage(‘http://keyword.discuz.com/related_kw.html?ics=utf-8&ocs=utf-8&title=‘.rawurlencode($title).‘&content=‘.rawurlencode(substrin($content,500)),‘utf-8‘);
    if($data) {
        $parser = xml_parser_create();
        xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0);
        xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, 1);
        xml_parse_into_struct($parser, $data, $values, $index);
        xml_parser_free($parser);
        $kws = array();
        foreach($values as $valuearray) {
            if($valuearray[‘tag‘] == ‘kw‘) {
                if(strlen($valuearray[‘value‘]) > 3){
                    $kws[] = trim($valuearray[‘value‘]);
                }
            }elseif($valuearray[‘tag‘] == ‘ekw‘){
                $kws[] = trim($valuearray[‘value‘]);
            }
        }
        return implode(‘ ‘,$kws);
    }
    return false;
}
//E 自动生成tag

2、打开module\article\article.class.php
搜索：
if($this->itemid) {
在前面增加：
//S 自动生成tag
if($post[‘tag‘]==‘‘ && $post[‘uptag‘]==1) $post[‘tag‘] = gettag($post[‘title‘],$post[‘content‘]);
//E 自动生成tag
