投票系统的代码总结

分析:  
我们利用一个文件(data.dat)来存储投票栏目.每个栏目占据一行.  
这样一来,便可随意加入和减去想要投票的栏目.  
我们再利用一个文件(votes.dat)来存储我们的投票结果.  
并纪录最近一位投票者的IP地址,简单的防止一人多投.  
所以,您应该在该程序目录下自行建立两个文件data.dat和votes.dat  
程序运行过程部分  
程序运行时应该先有一个投票的HTML表单,等待投票.  
当有人在HTML表单上投票时,判断它的IP是否为最近一位投票者的IP,  
如果此人刚刚投过票,则两个值应该相等,显示"您已投过票了，谢谢您的参与！"   
如果此人没投过票,则两个值不等,将它的投票写入文件(votes.dat)   
(这里得到投票者的IP方法是:Web客户机在对服务器发送请求时需要提供一个表识,  
这个表识就存储在环境变量REMOTE_ADDR里,我们引用它就可以了.)  
最后是显示投票结果,通常我们是以"条形图表+百分数"来显示投票情况.  
所以,我们要选择一个颜色单一的矩形图形,以适应横向缩放的要求.
