Free uploading of multi-user files without databases to the voting system (2) _ PHP Tutorial

Free uploading of multi-user files without databases to the voting system (2 ). This is the download.php of the system. The owner is responsible for downloading and recording. the file format is illustrated in. html? The input num in php indicates the file number to be downloaded. the ip address of the column to be downloaded by col does not time out. this is the download of the system. php is mainly responsible for downloading and recording data. the file format is described in the annotations.



// Input num as the file number to be downloaded, col = column to be downloaded
// Ip address no-timeout download count plus one

// File format
// 0 No. <1 Author <2 file location <3 voting count <4 Introduction <5 file size <6 file downloads
// Ip file format address: Project: Time


$ Uploadto = "../uploadfile/". $ col. "/"; // subdirectory to which the file is uploaded
$ Cgiroot = "http://eccct.51.net/cgi-bin/"; // add the current directory to the host

$ Pathtemp = explode ("/", $ HTTP_ENV_VARS ["PATH_INFO"]);
$ Pathtemp [sizeof ($ pathtemp)-1] = "";
$ Cgiroot = "http: //". $ HTTP_HOST.implode ("/", $ pathtemp); // add the current directory to the host

$ Ipfile = $ uploadto. $ col. ". ipd"; // download the ip address file
$ Overtime = 4; // timeout Hour
