首先要说明:这个不是主页计数器,虽然原理和它相同。                               
一:准备一个计数文件,存放链结的url和访问次数,格式如下                          
id|url|count                                                                     
id是用来查找的索引号,url为实际文件的地址,count为次数                           
实例数据:                                                                       
doc01|docs/doc01.html|10                                                         
doc02|docs/doc02.html|10                                                         
二:准备count.php文件,代码如下:                                                
//功能:传入参数id,在计数文件查找相应的url,增加计数,并返回实际的链接           
$countfile="count.txt";                                                          
$lines=file($countfile);//将计数文件内容读到数组$lines中                         
for($i=0;$i{                                                                                
list($sid, $url, $count)=explode("|", $lines[$i]);                               
                                        //分解字符串为$id,$url,$count            
if($sid==$id) //查找指定id                                                       
{                                                                                
$count+=1; //增加计数                                                            
$lines[$i]=$sid . "|" . $url . "|" . "$count" . "\n";//重新生成计数字符串        
break;                                                                           

}                                                                                
}                                                                                
//写入计数信息                                                                   
$fp=fopen($countfile, "w");                                                      
for($i=0;$ifputs($fp, $lines[$i]);                                                          
fclose($fp);                                                                     
Header("Location: $url");                                                        
?>                                                                               
注:这个是phpuser.com上的不完全版本,我加了一些改动,现在应该是能用的。          

三:主页中超链结的调用方式应该改为:                                             
doc01                                           
程序功能是:                                                                     
首先将计数文件内容读到数组中                                                     
再从数组中查找指定id号,如找到则$url为相应的文件的真正链接,再将计数加1,        
重新生成计数信息                                                                 
将计数信息写入文件中                                                             
返回链接                                                                         

四:访问人数引用就是下面这几句,写个function也可以,我偷了把懒,                 
                      谁写好了给我一个  :)                                       
$countfile="count.txt";                                                          
$lines=file($countfile);                                                         
list($sid,$url,$count) = explode("|",$lines[0]);//$lines[0]对应count.txt中       
                                                //第一条记录                     
echo $count;                                                                     
?>
