PHP5 and cookie reads

[lfbd]

Can someone tell me why I can't retrieve cookie information inside an object? Is this a bug in php5 or am I doing something wrong here?

class lfp_user {
       var $guid;
	function lfp_user() {
		if (isset($_COOKIE['lfp_guid'])) {
			$this->guid =$_COOKIE['lfp_guid'];
		} else {
			$this->guid = md5(uniqid(rand(0,1)*100,true));
			setcookie("lfp_guid",$this->guid,time()+60*60*24*365*2,"","127.0.0.1",true);
    		$_COOKIE['lfp_guid']= $lfp_guid; 
		}

	echo "LFP_USER.constructor: _COOKIE['lfp_guid']== '".$_COOKIE['lfp_guid']."'<br>";
	echo "LFP_USER.constructor: GUID == ".$this->guid."<br>";

	echo isset($_COOKIE['lfp_guid'])."<br>";
} // end constructor
} // end class

session_start();
session_register(); 					// is this necessary?
if (empty($_COOKIE['PHPSESSID'])) {			
		$_SESSION['lfp_user'] = new lfp_user();	

}	
// reload page again to see nothing in cookie:
print_r($_COOKIE);

If you open your cookies, you will see that it did work, but PHP can't retrieve the info.

Thanks!
