I have an interface that has constantly changing values (temperatures, date)
done in asp.net. I have a timer that refreshes the page every 5 seconds. The
problem is that the entire page rewrites every 5 seconds and looks horrid.

How might I do this in php? Would I have the same issue (rewrite).

Thanks mucho.
