Sending and receiving variables with flash and php

Hi there
I am trying to use flash to retrieve variables from a mysql database using php.
the Action Script I am using is

function showContent(){
    
    title_txt.text = this.title_txt;
    
}

var c = new LoadVars();
c.onLoad = showContent;

button.onRelease = function(){
    c.sendAndLoad("ShowFlash.php",c,"POST");
}

considering the php is returning all the variables as a string like [COLOR=Red]“title_text=a title&time_txt=12:45 pm&date_txt=some date[/COLOR]” what would I be doing wrong?
