Change DIV content using ajax, php and jQuery

I have a div which contains some text for the database:

<div id="summary">Here is summary of movie</div>

And list of links:

<a href="?id=1" class="movie">Name of movie</a>
<a href="?id=2" class="movie">Name of movie</a>
..

The process should be something like this:

1. Click on the link
2. Ajax using the url of the link to pass data via GET to php file / same page
3. PHP returns string
4. The div is changed to this string
