php文件服务实现虚拟挂载其他目录

复制代码 代码如下:

<?php
function base64url_encode($data) {
  return rtrim(strtr(base64_encode($data), \'+/\', \'-_\'), \'=\');
}
function base64url_decode($data) {
  return base64_decode(str_pad(strtr($data, \'-_\', \'+/\'), strlen($data) % 4, \'=\', STR_PAD_RIGHT));
}
function array_verify($var)
  {
   return isset($var)&&is_array($var) && count($var)>0;
  }
  function format_file_size($var)
  {
   if($var<1024) return $var.\' B\';
   if($var<1048576) return ($var/1024.0).\' K\';
   if($var<1073741824) return ($var/1048576.0).\' M\';
   return ($var/1073741824.0).\' G\';
  }

  $dir=\"F:\";//不以/结尾
  $path=\"\";

 if(array_verify($_GET)&&isset($_GET[\"path\"]))
 {
  $path=base64url_decode($_GET[\"path\"]);
  preg_match(\"#^[^/].*$|^.*\\.$|^\\..*$|\\./\\.|/\\.|\\./#\",$path,$temp);
    if(array_verify($temp))
   {
    echo
      \'<html>
               <head>
               <meta http-equiv=\"content-type\" content=\"text/html;charset=gb2312\" />
               <body>\';
           echo \"警告 index.php?path=\".$_GET[\"path\"].\" 非法url<br/></body></html>\";
     exit;
      }

 }

    {
 echo \'<html>

          <meta http-equiv=\"content-type\" content=\"text/html;charset=gb2312\" />
          <body>\';
 echo \"目录   <b>\".$path.\"</b><br/><br/>\";

 $dir_res=opendir($dir.$path);
 while($filen=readdir($dir_res))
     {
      if($filen!=\'.\'&&$filen!=\'..\')
      {
          if(is_file($dir.$path.\'/\'.$filen))

             }else
           {
                echo \'<a href=\"index.php?path=\'.base64url_encode($path.\'/\'.$filen).\'\" >\'.$filen.\"</a><br/>\\n\";
           }

         }else if($filen==\'..\')
             {
               preg_match(\"#([^/]+/{1})*[^/]+(?=/)#\",$path,$parent);
            if(array_verify($parent))
               {
                       echo \'<a href=\"index.php?path=\'.base64url_encode(\'/\'.$parent[0]).\'\" >\'.$filen.\"</a><br/>\\n\";
                  }else
          {

                   }
          }
     }

         </html>\';
 }
    else if(is_file($dir.$path))
        {
                $file_size = filesize($dir.$path);
                header(\"Content-type: application/octet-stream\");
                header(\"Accept-Ranges: bytes\");
                header(\"Accept-Length: \".$file_size);
                Header(\"Content-Disposition: attachment; filename=\".basename($dir.$path));
                readfile($dir.$path);//大文件请选择其他方式
           }else
            echo \"警告:非法访问!\";
