PHP版iis日志分析程序

说明: 将日志文件放在网站根目录,并改名为log.log。演示:http://www.jzxue.com/tools/iislog/ http://www.jzxue.com/tools/iislog/demo.gif

/*******************************************************
*功能:iis日志分析,分析出访问IP总数,搜索引擎抓取次数
*说明:
*       将日志文件放在网站根目录,并改名为log.log。
*演示:http://www.jzxue.com/tools/iislog/

*作者:blackli,建站学整理
*问题:搜索引擎蜘蛛地址不准确，尤其是google蜘蛛地址，国内流行的地址列
*       表存在相当大的误差,能力有限,不能够解决这个问题。有兴趣的可以参考
*       下面的网址.
