You can do an infinite-loop by using this:
do
{
SendDynamicWebPageAndQueryUserFormAction();
ProcessUserAction();
} while (true);
You may ask why in the world do anyone want to do an infinity-loop? I'm not trying to waste CPU
or trying to tie up the system here.
You often need to do this as the main program when someone accesses your dynamic web-page as
"index.php"
When you generate dynamic web-page, and process user's action depending on his/her response,
how in the world do you want to exit the program. If you do, what would the user's web-page
display? A black-hole?!
I suppose you can close their web-window if you are kind enough, or maybe shut-down their computer
if you are dubious enough :)
