PHP统计Nginx日志的User Agent数据

即将用到爬虫,于是打算收集一下User Agent(UA)数据。接着马上想到自己网站的访问日志不就是现成的优质数据源吗?于是愉快的决定写个脚本统计一下Nginx访问日志中的UA信息。

这类简单操作,用脚本语言就足够,毫无疑问肯定要用最熟悉的PHP。打开vim就开撸,十几分钟下来,功能简单的统计脚本就搞定了。

脚本目前有三个功能:1. 找出所有的UA信息并排序; 2. 统计操作系统数据; 3. 统计浏览器数据。程序运行截图如下:

  1. UA信息
  2. 操作系统信息
  3. 浏览器

用脚本统计最近一个月的访问日志,得到以下结果:

  1. 搜索引擎爬虫比较频繁,每天有好几千次数据访问;
  2. Windows仍是份额最大的操作系统,Linux桌面依然份额很小;
  3. Chrome目前是浏览器领域的霸主,其次是Firefox,Opera已经很小众了。

最后附上PHP脚本的代码,也可以从本人的Github里找到:https://github.com/qiquanji/Scripts/blob/master/statUA.php
