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.

return $referer;
}

}

}
}
return false;
}
function yxiao_seems_utf8($str) {
$length = strlen($str);
for ($i = 0; $i < $length; $i++) {

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);
