首先要說明：這個不是主頁計數(shù)器，雖然原理和它相同。                               
一：準(zhǔn)備一個計數(shù)文件，存放鏈結(jié)的url和訪問次數(shù)，格式如下                          
id url count                                                                     
id是用來查找的索引號，url為實際文件的地址，count為次數(shù)                           
實例數(shù)據(jù)：                                                                       
doc01 docs/doc01.html 10                                                         
doc02 docs/doc02.html 10                                                         
二：準(zhǔn)備count.php文件，代碼如下：                                                
<?php                                                                            
//功能：傳入?yún)��?shù)id,在計數(shù)文件查找相應(yīng)的url，增加計數(shù)，并返回實際的鏈接           
$countfile="count.txt";                                                          
$lines=file($countfile);//將計數(shù)文件內(nèi)容讀到數(shù)組$lines中                         
for($i=0;$i<count($lines);$i++)                                                  
{                                                                                
list($sid, $url, $count)=explode(" ", $lines[$i]);                               
                                        //分解字符串為$id,$url,$count            
if($sid==$id) //查找指定id                                                       
{                                                                                
$count+=1; //增加計數(shù)                                                            
$lines[$i]=$sid . " " . $url . " " . "$count" . "\n";//重新生成計數(shù)字符串        
break;                                                                           
                                                                                 
}                                                                                
}                                                                                
//寫入計數(shù)信息                                                                   
$fp=fopen($countfile, "w");                                                      
for($i=0;$i<count($lines);$i++)                                                  
fputs($fp, $lines[$i]);                                                          
fclose($fp);                                                                     
Header("Location: $url");                                                        
?>                                                                               
注：這個是phpuser.com上的不完全版本，我加了一些改動，現(xiàn)在應(yīng)該是能用的。          
                                                                                 
三：主頁中超鏈結(jié)的調(diào)用方式應(yīng)該改為：                                             
<a href="count.php?id=doc01">doc01</a>                                           
程序功能是：                                                                     
首先將計數(shù)文件內(nèi)容讀到數(shù)組中                                                     
再從數(shù)組中查找指定id號，如找到則$url為相應(yīng)的文件的真正鏈接，再將計數(shù)加1，        
重新生成計數(shù)信息                                                                 
將計數(shù)信息寫入文件中                                                             
返回鏈接                                                                         
                                                                                 
四：訪問人數(shù)引用就是下面這幾句，寫個function也可以，我偷了把懶，                 
                      誰寫好了給我一個  :)                                       
<?php                                                                            
$countfile="count.txt";                                                          
$lines=file($countfile);                                                         
list($sid,$url,$count) = explode(" ",$lines[0]);//$lines[0]對應(yīng)count.txt中       
                                                //第一條記錄                     
echo $count;                                                                     
?>
