I have my simple ajax based chat room, but i don't know how to display all active users on the right side of the chat window

Below is the code:

index.php

<?
session_start();

if(isset($_GET['logout'])){   
   
   //Simple exit message
   $fp = fopen("log.html", 'a');
   fwrite($fp, "<div class='msgln'><i>User ". $_SESSION['name'] ." has left the chat session.</i><br></div>");
   fclose($fp);
   
   session_destroy();
   header("Location: index.php"); //Redirect the user
}

function loginForm(){
   echo'
   <div id="loginform">
   <form action="index.php" method="post">
      <p>Please enter your name to continue:</p>
      <label for="name">Name:</label>
      <input type="text" name="name" id="name" />
      <input type="submit" name="enter" id="enter" value="Enter" />
   </form>
   </div>
   ';
}

if(isset($_POST['enter'])){
   if($_POST['name'] != ""){
      $_SESSION['name'] = stripslashes(htmlspecialchars($_POST['name']));
   }
   else{
      echo '<span class="error">Please type in a name</span>';
   }
}
?>
<head>
<title>Chat - Customer Module</title>
<link type="text/css" rel="stylesheet" href="style.css" />
</head>

<?php
if(!isset($_SESSION['name'])){
   loginForm();
}
else{
?>
<div id="wrapper">
   <div id="menu">
      <p class="welcome">Welcome, <b><?php echo $_SESSION['name']; ?></b></p>
      <p class="logout"><a id="exit" href="#">Exit Chat</a></p>
      <div style="clear:both"></div>
   </div>   
   <div id="chatbox"><?php
   if(file_exists("log.html") && filesize("log.html") > 0){
      $handle = fopen("log.html", "r");
      $contents = fread($handle, filesize("log.html"));
      fclose($handle);
      
      echo $contents;
   }
   ?></div>
   
   <form name="message" action="">
      <input name="usermsg" type="text" id="usermsg" size="63" />
      <input name="submitmsg" type="submit"  id="submitmsg" value="Send" />
   </form>
</div>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script>
<script type="text/javascript">
// jQuery Document
$(document).ready(function(){
   //If user submits the form
   $("#submitmsg").click(function(){   
      var clientmsg = $("#usermsg").val();
      $.post("post.php", {text: clientmsg});            
      $("#usermsg").attr("value", "");
      return false;
   });
   
   
   function loadLog(){      
      var oldscrollHeight = $("#chatbox").attr("scrollHeight") - 20;
      $.ajax({
         url: "log.html",
         cache: false,
         success: function(html){      
            $("#chatbox").html(html);

            var newscrollHeight = $("#chatbox").attr("scrollHeight") - 20;
            if(newscrollHeight > oldscrollHeight){
               $("#chatbox").animate({ scrollTop: newscrollHeight }, 'normal'); //Autoscroll to bottom of div
            }            
           },
      });
   }
   setInterval (loadLog, 2500);   //Reload file every 2.5 seconds
   
   //If user wants to end session
   $("#exit").click(function(){
      var exit = confirm("Are you sure you want to exit?");
      if(exit==true){window.location = 'index.php?logout=true';}      
   });
});
</script>
<?php
}
?>
</body>
-----------------------------------------------------------------------

post.php

<?
session_start();
if(isset($_SESSION['name'])){
   $text = $_POST['text'];
   
   $fp = fopen("log.html", 'a');
   fwrite($fp, "<div class='msgln'>(".date("g:i A").") <b>".$_SESSION['name']."</b>: ".stripslashes(htmlspecialchars($text))."<br></div>");
   fclose($fp);
}
?>

--------------------------------

log.html to put all the text

EDIT: use code tags next time
