php页面

<?php

$file = $_GET[‘f‘];
$arr = [
    ‘7337e2f117b38edd90ef8ddd50c31406‘ => [‘./images/baobao.jpg‘,‘宝宝图片.jpg‘],‘3c78b35502b2693fefdfc51cba3a53a5‘ => [‘./images/manual.rar‘,‘php手册.rar‘],‘bdd5af62d46f0222f61908a1cff92f16‘ => [‘./images/stu.avi‘,‘视频教程.avi‘]    
];

//告诉浏览器内容类型为8位的二进制数据流
header("Content-Type:application/octet-stream");
//告诉浏览器的数据处置方式,为附件方式保存
header("Content-Disposition:attachment;filename=". iconv(‘utf-8‘,‘gbk‘,$arr[$file][1]));

$handle = fopen($arr[$file][0],‘rb‘);//var_dump()打印看看,果然有resource文件,没问题
while($str = fread($handle,1024) )
{
    echo $str;
}

其中 7337e2f117b38edd90ef8ddd50c31406? 这些是MD5加密后的数据.
