Calling a function

I have a function that will pull data from a php file. I also have a timer that when it finishes a cycle of 10 seconds it will run the function that fuctions that grabs data from the php file.

What my question is if I have a script that is pulling the data:

function loadTestimonials(e:Object):void
	for(var i:int=0; i<e.length; i++)
		testimonials.text = e*.testimonials;
		from.text = e*.from;
		/*trace(e*.testimonials + " - " + e*.from);*/

How do I call that function again from my timer function?

import flash.utils.*;
var tTimer:Timer = new Timer(10000);
tTimer.addEventListener(TimerEvent.TIMER, loadTestimonials);


function changeTestimonials(eventArgs:TimerEvent)
