cookies and sessions

[luiddog]

I have this code. What I'm trying to do is if a cookie exsits then the session should equal the cookie. If a cookie does not exsists and a session exsists then leave the session as it was. If a cookie does not exsists and a session doesn't exisit then set a cookie and create a session with the same value. What am I doing wrong with this code:

session_start();
if (!isset($_COOKIE['b'])) {
if (!isset($_SESSION['a'])) {
   $RAND = rand(1,5);
   $_SESSION['a'] = $RAND;
   setcookie(b,$RAND,time()+60*60*24*30);
}
} else {
$_SESSION['a'] = $_COOKIE['b'];
}

It works fine if cookies are enabled but when they are disabled it keeps resettig the session variable.

I think something like this might work:

<?php
session_start(); 

// if cookie exsits:
if(isset($_COOKIE['b'])) 
{ 
	$_SESSION['a'] = $_COOKIE['b']; 
	echo '$_COOKIE[b] is set and equals: '.$_COOKIE['b'];
}

// else no cookie exists:
else
{
	// if session doesn't exist
	if(!isset($_SESSION['a'])) 
	{
		// set cookie and create session var with same value
		$_SESSION['a'] = rand(1,5); 
		$cookie = setcookie('b', $_SESSION['a'],time()+60*60*24*30);
		echo '$_COOKIE[b] and $_SESSION[a] values are being set to: '.$_SESSION['a'];
	} 

// else, cookie does not exsist BUT session var exsists:
else
{ 
	echo 'there is no cookie, but $_SESSION[a] is set and equals: '.$_SESSION['a'];
}
}
?>
