Free multi-user file upload voting system without database 2

This is the download.php of this system, which is mainly responsible for downloading and counting. The file format is explained in the comments.

//Input num is the file number to be downloaded, col= Column to be downloaded
//Add one to the number of IP downloads without timeout
//File format
//0Number<1 Author<2File location<3Vote count<4Introduction<5File size< 6 Number of file downloads
//ip file format Address: project: time
$uploadto="../uploadfile/".$col."/";//Subdirectory uploaded to
$cgiroot="http:// eccct.51.net/cgi-bin/"; //Host plus current directory
$pathtemp=explode("/",$HTTP_ENV_VARS["PATH_INFO"]);
$pathtemp[sizeof($pathtemp)-1]= "";
$cgiroot="http://".$HTTP_HOST.implode("/",$pathtemp);//Host plus current directory
$ipfile=$uploadto.$col.".ipd";// IP file for download
