Accessing variables defined in a function

[BastianR]

Hi all,
I have been playing around with combining flash and PHP/Mysql for some time now, mainly sending one flash variable to a PHP file and then retrieving a result and turning it back into a different flash variable. My problem is i've got to the stage where I need to access these variables from other functions. Now I think I need to find some way of defining them outside of the function, maybe using global vars? Well i'm not gonna pretend I know anything about it. The two functions from which I access my PHP variables is as follows:

function btnDown(event:MouseEvent):void {

var variables:URLVariables = new URLVariables();
var varSend:URLRequest = new URLRequest("http://localhost/test.php");
varSend.method = URLRequestMethod.POST;
varSend.data = variables;
var varLoader:URLLoader = new URLLoader;
varLoader.dataFormat = URLLoaderDataFormat.VARIABLES;
varLoader.addEventListener(Event.COMPLETE, completeHandler);
variables.uname = Username_text.text;
variables.sendRequest = "parse";    
varLoader.load(varSend);
        
        function completeHandler(event:Event):void{
    
    var phpVar1 = event.target.data.var1;

So I need a way to access the phpVar1 variable in a totally seperate function and i'm not really sure how
Any suggestions would be much appreciated, thanks

I'm no genius when it comes to AS, but I think your only two options are to either make the var global by defining it outside your functions or passing it to another function (eg)

function firstFunction():void
{
var someVariable:Number = 10;
secondFunction(someVariable);
}

function secondFunction(passedVariable:Number):void
{
trace (passedVariable);
}

Hope that helps?

define it outside the function. Variables declared inside functions are local variables and don't exist outside of that function.

Thanks for the replies.
What exactly would I define the variable as? Although it's a number defining it as one returns Nan, is there a special term for defining variables coming from PHP?

Define it in the class.

I've never really bothered using classes yet in AS3, could you give me a little snippet of example code to explain what you mean? thanks

class SXdwgewd extends Sprite {
var tsad;
