PHP记录用户通过搜索引擎进网站的关键词并给出相关结果

本文章给大家介绍PHP记录用户通过搜索引擎进网站的关键词并给出相关结果,有需要了解的同学可进入参考,下面是进入你网站的情况的相关实现代码,更多的,大家自己拓展,代码如下:

 'word',
        'google.com' => 'q',
        'sina.com.cn' => 'word',
        'sohu.com' => 'word',
        'msn.com' => 'q',
        'bing.com' => 'q',
        '163.com' => 'q',
        'yahoo.com' => 'p'
    );
    $keyword = '';
    $sengine = $p['host'];
    foreach ($arr_sd_key as $se => $kwd) {
        if (strpos($p['host'], $se) !== false) {
            $keyword = $pa[$kwd];
            $sengine = $se;
            break;
        }
    }
    $sql = "insert into visit_log(domain,key_word,ct)";
}
?>
上面的代码实现不了根据用户来的词给出相关结果,下面我来再进行调上面的函数,代码如下:
> 6)) . chr(0x80 | ($val & 0x3f));
            else $ret.= chr(0xe0 | ($val >> 12)) . chr(0x80 | (($val >> 6) & 0x3f)) . chr(0x80 | ($val & 0x3f));
            $i+= 5;
        } else if ($str[$i] == '%') {
            $ret.= urldecode(substr($str, $i, 3));
            $i+= 2;
        } else $ret.= $str[$i];
    }
    return $ret;
}
function ls_get_delim($ref) {
    $search_engines = array(
        'google.com.hk' => 'q',
        'google.com.tw' => 'q',
        'go.google.com' => 'q',
        'google.com' => 'q',
        'blogsearch.google.com' => 'q',
        'cn.bing.com' => 'q',
        'one.cn.yahoo.com' => 'p',
        'baidu.com' => 'wd',
        'soso.com' => 'w',
        'youdao.com' => 'q',
        'sogou.com' => 'query'
    );
    $delim = false;
    // 判断
    if (isset($search_engines[$ref])) {
        $delim = $search_engines[$ref];
    }
    return $delim;
}
function ls_get_refer() {
    // 判断前一页面的 URL 地址
    $queryString = $_GET['referer'];
    $queryString = unescape($queryString);
    if (!isset($queryString) || ($queryString == '')) return false;
    $referer_info = parse_url($queryString);
    $referer = $referer_info['host'];
    //去除www.
    if (substr($referer, 0, 4) == 'www.') $referer = substr($referer, 4);
    return $referer;
}
function ls_getinfo($what) {
    $referer = ls_get_refer();
    if (!$referer) return false;
    $delimiter = ls_get_delim($referer);
    if ($delimiter) {
        $terms = ls_get_terms($delimiter);
        if ($what == 'isref' && $terms != '') {
            return true;
        }
        if ($what == 'terms') {
            echo $terms;
        }
    }
    return false;
}
function yxiao_seems_utf8($str) {
    $length = strlen($str);
    for ($i = 0; $i < $length; $i++) {
        $c = ord($str[$i]);
        if ($c < 0x80) $n = 0; // 0bbbbbbb
        elseif (($c & 0xE0) == 0xC0) $n = 1; // 110bbbbb
        elseif (($c & 0xF0) == 0xE0) $n = 2; // 1110bbbb
        elseif (($c & 0xF8) == 0xF0) $n = 3; // 11110bbb
        elseif (($c & 0xFC) == 0xF8) $n = 4; // 111110bb
        elseif (($c & 0xFE) == 0xFC) $n = 5; // 1111110b
        else return false; // Does not match any model
        for ($j = 0; $j < $n; $j++) { // n bytes matching 10bbbbbb follow ?
            if ((++$i == $length) || ((ord($str[$i]) & 0xC0) != 0x80)) return false;
        }
    }
    return true;
}
function ls_get_terms($d) {
    //取得查询值
    $queryString = $_GET['referer'];
    $queryString = unescape($queryString);
    $query_str = parse_url($queryString);
    parse_str($query_str[query], $query_str);
    $query = $query_str[$d];
    $query = urldecode($query);
    $query = str_replace("'", '', $query);
    $query = str_replace('"', '', $query);
    $query_array = preg_split('/[s,+.]+/', $query);
    $query_terms = implode(' ', $query_array);
    $terms = htmlspecialchars($query_terms);
    //gbk->utf8
    if (!yxiao_seems_utf8($terms)) {
        $terms = iconv("GBK", "UTF-8//IGNORE", $terms);
    }
    return $terms;
}
if (ls_getinfo('isref')) {
    document . write('

'); < ? php
}
