其它网站通过一链接<a hrer="http://www.myweb.com/pin/index.php?from=7">亲密网</a>到达我的网站 http://www.myweb.com/pin/index.php ,这时我可以把from值取出来,放到我的index.php页面的所有链接中
具体实施我就不记得了,楼主可以用google查一下
她们是<a target='_blank' href="http://www.xxx.com/index.php?val=1" onclick="">第一</a>名.
我们是<a href="http://www.xxx.com/index.php?var=2">第二</a>名.
你们是<a href="http://www.xxx.com/index.php?val=1">第三</a>名.
