Hi, I have a problem with my php/mysql script. It should only output the while loop once but I am getting unlimited loops and an endless page.

$query = mysql_query("SELECT * FROM users WHERE username ='".base64_encode($_SESSION['username'])."' LIMIT 1"); 
$result = mysql_fetch_array($query);
   if(empty($result)){
      echo "No user... Error";
   }else{
   while($row = $result){
   ?>
<a href="index.php?user=<?=$row['id']?>"><?=base64_decode($row['username'])?></a> | <a  href="javascript:void(0);" id="logout">Logout</a>
   <?php
   }
}

I have tried a similar script with these same lines and it works perfectly

  $result = mysql_fetch_array($query);
   if(empty($result)){
      echo "No user... Error";
   }else{
   while($row = $result){
      //Something
   }
}
