Find user id

Anonymous
I'm really way out of my depth here in this forum.
But anyway, I'm trying to write a bit of php on a staic page and I wanted to know is there anyway to find out if a user is logged in or not.
Is there a global variable for the users ID. If it isn't set to null then I'd know user is logged in and registered.
Anyone have any ideas?
Regards,

you may need to declare this global depending upon your script...
$_USER['uid'] will be '1' for anonymous, '2' for root, above 2 for logged in members.

I think I have that right. Wink
Hope that helps

$_USER['uid'] may also be empty for anonymous users.

Tried:

global $_USER['uid'];
$test =$_USER['uid'];
echo $test;

Obviously this is not how to declare global variables.
So how is it done?

(There is absolutely nothing else on the page.
I just want to get the user ID into a variable.)

May I suggest reading a book or online resource about PHP?

global $_USER;
echo $_USER['uid'];

bye, Dirk

Aren't global variables not defined elsewhere is geeklog. Like when someone logs in. And all I want to do is use that variable. For example just to simply echo it.
Why is it not as simple as this?

Of course global variables are defined elsewhere, but obviously must be declared wherever I want to use them.
Doh! - that was a mistake

Big Celebration
Found exactly what I was looking for at:
here

For anyone interested, this works for me:

global $_CONF, $_USER;
print ("username={$_USER['username']}
");
print ("userid={$_USER['uid']}
");
print("remote address= {$_SERVER['REMOTE_ADDR']}
");
print("http remote address {$HTTP_SERVER_VARS['REMOTE_ADDR']}
");
print("site url= {$_CONF['site_url']}
");

Big Celebration Very Happy
