Multi-user files without a database free upload voting system (2) _php tutorial

This is the system of download.php, mainly responsible for downloading and counting, wherein the file format is described in the comments.



Incoming num is the file number to download, col= the columns to download
IP does not timeout download count plus one

File format
0 Ref. &LT;1 Author <2 file location <3 poll Count <4 introduction <5 file size <6 file download times
IP file Format address: Project: Time

Remove IP file

Absolute time




Remove the timeout IP
