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:
- $rfr = $_SERVER['HTTP_REFERER'];
-
-
- if($rfr)
- {
- $p=parse_url($rfr);
- parse_str($p['query'],$pa);
- $p['host']=strtolower($p['host']);
- $arr_sd_key=array(
- 'baidu.com'=>'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;
- }
- }
- $sql="insert into visit_log(domain,key_word,ct)";
- }
上面的代码实现不了根据用户来的词给出相关结果,下面我来再进行调上面的函数,代码如下:
- <?php
- function unescape($str) {
- $ret = '';
- $len = strlen($str);
- for ($i = 0; $i < $len; $i++) {
- if ($str[$i] == '%' && $str[$i +1] == 'u') {
- $val = hexdec(substr($str, $i +2, 4));
- if ($val < 0x7f)
- $ret .= chr($val);
- else
- if ($val < 0x800)
- $ret .= chr(0xc0 | ($val >> 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];
- }
