as3 and php variables issue - php

Question

I have a MySQL database and I access it through PHP script. The issue I have is that the variables returned from PHP are always the same.
First time I run the code (add/remove records in the database) every thing is correct, but if I'm running it again (add/remove) PHP reports back to AS3 the same records as before. running the php directly in the browser returns are correct.
hope someone can help me... I'm getting crazy!
here are my codes:
AS3
function sendSqlData(event:Event):void
{
playlistDateString = "&playlistDateString="+playlistDate.getFullYear().toString()+monthDigit+playlistDate.getMonth().toString()+dayDigit+playlistDate.getDate().toString();
playlistSongNr = "&playlistSongNr="+ song;
songTime ="&songTime="+ Math.floor(channel.position);
var phpUrl:String = "send_data.php";
var phpUrlRequest:URLRequest = new URLRequest(phpUrl+parseMe+playlistDateString+playlistSongNr+songTime);
scriptLoader = new URLLoader();
scriptLoader.addEventListener(Event.COMPLETE, sendSqlDataComplete);
scriptLoader.load(phpUrlRequest);
}
function getSqlData(event:Event):void
{
var phpUrl:String = "get_data.php";
var phpUrlRequest:URLRequest = new URLRequest(phpUrl+parseMe);
// phpUrlRequest.method = URLRequestMethod.POST;
scriptLoader = new URLLoader();
// scriptLoader.dataFormat = URLLoaderDataFormat.TEXT;
scriptLoader.addEventListener(Event.COMPLETE, getSqlDataComplete);
scriptLoader.load(phpUrlRequest);
}
function sendSqlDataComplete(event:Event):void
{
scriptLoader.removeEventListener(Event.COMPLETE, sendSqlDataComplete);
var phpVars:URLVariables = new URLVariables();
phpVars.decode(event.target.data);
getSqlData(event);
}
function getSqlDataComplete(event:Event):void
{
scriptLoader.removeEventListener(Event.COMPLETE, getSqlDataComplete);
var phpVars:URLVariables = new URLVariables();
phpVars.decode(event.target.data);
var phpString = event.target.data.toString();
var patterns:Array = ["id\\d{0,5}=\\d{0,5}", "playlistDate\\d{0,5}=\\d{0,8}", "playlistSongNr\\d{0,5}=\\d", "songTime\\d{0,5}=\\d{0,7}"];
for (var j:int = 0; j < 4; j++)
{
var pattern:RegExp = new RegExp(patterns[j],"g");
var tempStrings:Array = phpString.match(pattern);
for (i = 0; i < Number(phpVars.records); i++)
{
switch (j)
{
case 0:
ids[i] = Number(tempStrings[i].substring( tempStrings[i].indexOf("=")+1 ));
break;
case 1:
playlistDates[i] = Number(tempStrings[i].substring( tempStrings[i].indexOf("=")+1 ));
break;
case 2:
playlistSongNrs[i] = Number(tempStrings[i].substring( tempStrings[i].indexOf("=")+1 ));
break;
case 3:

break;
}
}
tempStrings = null;
}
fillDataGrid(Number(phpVars.records));
}

It seems that your response is being cached when you call it from ActionScript. You can add a microtime value to the end of the URL (which will prevent caching).
var phpUrl:String = "get_data.php?" + new Date().getTime();
