How do i check if user is logged on or not?
i would like to echo different links on each page depending on if the user is logged on or not,
e.g "log on" or "register" if they are not and "change style" if they are,
how do i do this?

thanks..

I think you might want to use the $_SESSION superglobal to do this maybe...

how is your log in set up? when i say that is how do you tell when the user is logged in our not, that is if you have it set up in the 1st place. If not you would parse the user input and check it against the records in the db if everything is set then you would assign the username to a $_SESSION var.
PHP Code:
 $_SESSION['user_name'] = $username_they_entered; 


now if you are testing whether they are logged in or not you would simply go
PHP Code:
if(isset($_SESSION['user_name']))
{
//print something you only want the person logged in to see
//maybe there username
print "Welcome $_SESSION['user_name']" ;
}
else
{
print 'Welcome Guest. Would you like to register?' ;
}
