Interacting with server without a refresh?

This veers a bit from PHP, but is relevant.

I am building an interactive workshop tool using php and mysql.

I want the facilitator to be able to control which pages the
participants see and to be able to control the data that appears on the
page. The obvious way to do this would be to have regular page
refreshes. This would reload the page bringing in new data from the db,
or could pull in entire new pages using includes.

However, page refreshes are less than elegant - and can cause problems
if, for example, I want to have a form on a page. I am wondering if
there are alternative methods - presumably using something clientside -
that could check the server and only do a refresh if new data/new page
or somesuch is available.

I hope this is clear.

Thanks,

Jeffrey

It's called ajax.

There are tons of tutorials around on the 'net, a quick search will find
you some.
