说明:在处理时,记得处理好编码的问题,因为不同的搜索引擎,返回的结果,有的可能是GBK,有的则可能是UTF-8格式的内容。

函数2,这个也不错,大家可以试试。 代码如下:

  1. //获取搜索引擎的入口关键字
  2. $_SERVER['HTTP_REFERER']='http://www.baidu.com/s?wd=http://bbs.it-home.org';
  3. echo save_www_iiwnet_com_keyword('http://www.baidu.com/s?wd=http://bbs.it-home.org','http://www.baidu.com/s?wd=http://bbs.it-home.org');
