This is the last article of this article, mainly describes how to use the system, let us use a case to illustrate:
For example, we want to do flash work upload vote, then we just need to in. /uploadfile/(relative to the location of the system PHP file) A Flash subdirectory is built, and in which the following files are created: Flash.if (the caption that appears when the record appears), Flash.ip (voting IP record), FLASH.IPD (download IP record), Flash.lst (download file information record). Then use the View.php?col=flash to use the system, if you want to add new columns/user PHP works upload, just in. /uploadfile/under a different subdirectory PHP, and the corresponding file, and use view.php?col=php can be used</文件下载次数>
The above describes the voting system without the database of multi-user files free upload voting system 3, including the voting system content, I hope the PHP tutorial interested in a friend helpful.
