Problem with Flash and PHP

So I made this voting thing where you click 6 of 12 boxes and that would send the info to a .php and to a database, but I’m having trouble figuring out how to set up the .php… Here’s my actionscript:

var myLv:LoadVars = new LoadVars();
var resultArray:Array = ["empty"];
var totalPressed:Number = 0;

stop();
for (i=1;i<13;i++) {
    this["box"+i].id = i;
    this["box"+i].onRelease = function() {
        judgeAmount(this,this.id);
    };
    resultArray.push(0);
};

function judgeAmount(box:MovieClip,idNo:Number):Void {
    if (box._currentframe == 2) {
        totalPressed--;
        resultArray[idNo] = 0;
        this["box"+idNo].voting = 0;
        box.gotoAndStop(1);
    }
    else {
        if (totalPressed < 6) {
                box.gotoAndStop(2);
            resultArray[idNo] = 1;
            this["box"+idNo].voting = 1;
            totalPressed++;
        }
    };
    if (totalPressed == 6) 
    {
        submit._alpha = 100;
        submit.enabled = true;
    }
    else 
    {
        submit._alpha = 0
        submit.enabled = false;
    }
}
submit.onRelease = function():Void
{
    sendVars();
    _root.gotoAndStop(2);
}
myLv.onLoad = function():Void
{
trace("data sent");
}
function sendVars():Void
{
    var len:Number = resultArray.length;
    for (i=1;i<len;i++)
    {
        myLv["var"+i]=resultArray*;
    }
    myLv.sendAndLoad("myphp.php",myLv,"POST");
}

Now I’m just wondering how should I set up the .php to receive the information? Do I put all the instance names of the movieclips (box 1, box 2, box 3, etc…) or do I some how set it up to receive the array… I’m really confused on the subject. :puzzle:
