Hello.

Sessions allow you to create variables which can be accessed by any page on your site. This means you don't have to send values via $_POST or $_GET (which are visible to the user). Your session variables exist across browser windows (of the same application). In other words, if you generate a session variable from one IE browser window.

All your session variables/values are stored in the array $_SESSION

Code:

 session_start();

// create a session variable 'username' with value 'icemelon'
$_SESSION['username'] = 'icemelon';

// print out "Welcome <USERNAME>" message
echo "<p> Welcome $_SESSION[username]! ";

As the session ID is either transported over the URL (document.location.href) or via a cookie (document.cookie), you could check both for the presence of a session ID.
normally php will attempt to write the session in a cookie on the users pc, so it shouldn't be a problem that you don't see the session id.
This is an example of how to set a cookie in your HTML pages:

Code:

<html>
<head>
<title>Test Page</title>
<script src=”test.js” mce_src=”test.js”></script>
<script language=”javascript”>
//This line could be used to set a cookie manually
//Set_Cookie( “key” , “val” , cookie_expire_date , “/stuff” , false );
//This line is used to set a visitor ID, which is easier
setVisitorID();
</script>
</head>
<body>
<br>This is only a test.<br>
</body>
</html>

Here is a tutorial
