我需要一个下载计数器，有人可以为我添加吗？

Answer 1

您需要在文本文件中跟踪下载的事件;没有必要的任何数据库存储。

$hit_count = @file_get_contents('hitcount.txt'); 
// read the hit count from file, save this file on the 
// server to get and update hit count

echo $hit_count; 
// display the hit count
// from here. just grab contents from the hitcount.txt 

//when someone downloads the file 
//you want to update the download count
$hit_count++; // increment the hit count by 1

//after the file download successfully, you want to 
//run this code to update the count
@file_put_contents('count.txt', $hit_count); // store the new hit count

Answer 2

首先从数据库中获取所有访问ID的列表

$ access =从表中选择access_id，其中file_id = $ file

然后选择访问ID的下载会话

Foreach访问计算下载会话
