Is it possible to have an image map submit the coordinates clicked to a PHP script?
I'm pretty sure web browsers let you do this, but not really sure how to make PHP aware that they exist.
What I'm after is a simple script that will tell me the coordinates of the image map that the user selected.

Figured it out, for anybody who's interested.
xHTML:
ismap="ismap" />
The ismap="ismap" attribute makes the browser append the x and y coordinates to the HREF URL as a query string, such as: map.php?125,467, with the x coordinate being first and the y coordinate being second. The PHP script can read this through its $_SERVER['QUERY_STRING'] superglobal
PHP:
$coords = explode(",",$_SERVER['QUERY_STRING']); # Split coordinates.
$x = trim($coords[0]); # Assign $x the x coordinate.
$y = trim($coords[1]); # Assign $y the y coordinate.
?>

Yeah, the x and y coords related to the image, such as "user clicked: x - 172px, y - 65px".
I'm sure that it was built into HTML image maps, but was never sure how it worked, nor if its part of xHTML.
Its been a while since I've done anything major with JavaScript too. Do you mean have JS take note of the coords clicked and then append it to the URL link as a query string?

You mean the x and y coords of the mouse when you click a link? I'm pretty sure JavaScript can do it, but can't remember how exactly.
