dynamic mysql search with JavaScript and PHP

[25kuwait]

I'm trying to code a dynamic MySQL search box with JS and PHP. Basically I have a single table, and when the user begins typing a name in the search box, the HTML table below dynamically updates based on what the user is typing (think Google's instant search suggestions). The only other requirement is that it has to also support comma-deliminated lists, so the user could type "john, frank, joe" and it would show all the names that match those results.Any tips / pointers for how I could do this? The Database will have a couple hundred entries -- 1500 at most.Thanks!
