Convert serialized string from PHP to array in AS3.0

Question

Hi there

I'm busy communicating with my Flash file with a PHP script which in turns communicates with my db, I need to pass an array from PHP back to Flash, which happens correctly I assume, but I'm unable to unserialize the string correctly when it returns, my string looks like this:

memberNum=2&success=1&teamMemberID%5B0%5D=1&teamMemberID%5B1%5D=2

I use this data by using the com.frigidfish.FlasPHP package I got from here: http://www.as3blog.org/?p=18.

My problem is however here:

function processPHPVars(event:Event){
    // put the object that php sends back into a var (in this case phpData)

    phpData = event.target.receivedVars;

    if (phpData.success) {
        trace(phpData.memberNum);
        // I'M STRUGGLING HERE TO TRACE THE CORRECT VALUE FOR THIS ARRAY
        trace(phpData.teamMemberID[0]);
    }
}

I keep getting the following error:

TypeError: Error #1010: A term is undefined and has no properties.

The whole AS3.0 section looks like this:

import com.frigidfish.FlashPHP;

var memberNum:Number = 0;
var teamMemberID:Array = null;
var phpData:*;

var memberNumObject:Object = new Object();
memberNumObject.memberNum = memberNum;
memberNumObject.teamMemberID = teamMemberID;

var flashPHP:FlashPHP = new FlashPHP("http://www.strikeproductions.co.za/team_getMembers.php", memberNumObject);
flashPHP.addEventListener("ready", processPHPVars);

function processPHPVars(event:Event){
    // put the object that php sends back into a var (in this case phpData)

    phpData = event.target.receivedVars;

    if (phpData.success) {
        trace(phpData.memberNum);
        trace(phpData.teamMemberID[0]);
    }
}

The easiest way to communicate between Flash and PHP is to use JSON. Look at this post, this will show you how to use it : http://stackoverflow.com/questions/1653514/actionscript-3-and-json
