It will definitely help to use one of those libraries to simplify making and
handling the response to the AJAX request.

It might also help to remember that it's *just a request* and you can
write and test the server side of it completely independently.

Decide what format you want your data to come back in: JSON, XML,
plain text, HTML snippet, whatever.

Create a PHP "page" that takes your request and any parameters,
fetches the data and formats it appropriately. View that page in your
browser; adjust as necessary. Now you're mostly done.  :-)

Look at your JS library's docs on how to generate an AJAX request.
It'll probably be something like (pseudocode)

AJAXRequest(url, method,
   params: { 'texture' = 'fuzzy' },
   success: { alert('it worked'); },
   error: { alert('aw rats'); })

where you can replace that "success" action with one to, say, replace
the contents of a paragraph with the received content. I'm not familiar
with MooTools documentation but look at the jQuery docs examples,
like <http://api.jquery.com/jQuery.get/>.
