How to pass data from php to flash?

[Erickk]

Hi, i am a beginner in PHP n Flash.
My question is how to display Facebook logged in username and profile image into Flash by using Flashvar??
Here is the php code please check whether it is correct or not?

 <?php
//include  facebook api etc.
require_once("facebook/facebook.php");

//create  new facebook instance
$facebook = new Facebook('xxx', 'xxx');

//prompt  the user to login
$fb_user = $facebook->require_login();


//check  if the user has added the app
if  (!$facebook->api_client->users_isAppUser()) {
          //if  not, redirect him to add it
               $facebook->redirect($facebook->get_add_url());
}
//select  the profile image
      $photoData =  $facebook->api_client->users_getInfo($fb_user, 'pic_big'); 
       $photo = $photoData[0]['pic_big'];
//select the profile name
       $tmp=$facebook->api_client->fql_query("SELECT name FROM user  WHERE uid=$user");
      $nam=$tmp[0]["name"];


?>
       <!-- flash file -->
      <fb:swf  swfsrc='http://xxx/app/fbtest.swf' allowscriptaccess='never'  bgcolor='#ffffff' wmode='transparent'  flashvars='u_img=<?php echo  urlencode($photo);?>& u_name=<?php echo urlencode($nam);?>'  width='500' height='400'/>

And for the Flash part i do not know how to write the code into it.
The component i will be using is UILoader for the Image and Textfield for name.
Please kindly help me out.
Thankyou.
