This is the last article in this article. It mainly introduces how to use the system. Let's use an example to illustrate it:

For example, if we want to upload and vote for flash files, we only need .. /uploadfile/(relative to the location of the system PHP file) create a flash subdirectory and create the following files: flash. if (the title displayed when the record is displayed), flash. ip (Voting ip records), flash. ipd (download ip records), flash. lst (download file information record ). then use view. php? Col = flash, you can use the system. If you want to add a new column/user to upload php files, you only need .. /uploadfile/create another subdirectory php, and the corresponding file, and use view. php? Col = php.
