There are three files in total, namely: index.htm, action.php, main.htm
The principle is that the front page main.htm and the background action.php are organized through the page frame index.htm, and the action. The page width of php is set to 0, which does not affect the display. action.php puts information into cookies, and main.htm implements interaction by reading cookies. In main.htm, you can also control the background CGI program by re-reading action.php.
