your server routine is just a web page,wait for the browser to request.you
set up the autocomplete like this:
$(..).autocomplete(web_page_url,{options..}).every time when the user press
a key,autocomplete will make a request to your web page,you fetch the
parameter q,and you will know what the user have put in the autocomplete
textfield.then you run your routine,and at last,write the response like
this:
fog
fox
one item a line,so autocomplete will know.
the autocomplete plugin bundle file comes with some .php files,that is
server-side code,you can review it.
