hello.. often I'd like to discriminate between anonymous and logged-in users.
I saw that with the right permissions I can use php on my content and I have the feeling that there must be an API function that return the "status" of the user, so I can use it to display separate messages.

Can anyone point me to the right place? Thank you ;-)

There is no API, code just uses the global $user, something like this

<?php
global $user;

if ( $user->uid ) {
  // They are logged in
}
else {
  // They are not loggin in
}
?>

thanks, works greatly ;-)

Where can I get all the globals I can use ?

The easiest way I know of to get a list of all the globals is to print them out in your node or theme file using:

<pre><?php print_r($GLOBALS) ?></pre>

That will give you a formatted list of all the superglobals(all caps) and globals.

For a more detailed explanation see http://drupal.org/node/46200.

To save you some time, if you read past the superglobals and get to drupal's globals you won't find anything else of much interest. Most of the rest hold just a string and some are interesting only in a limited context. A grep in the core files shows:

$GLOBALS['user']

$GLOBALS['db_type']
$GLOBALS['active_db']
$GLOBALS['base_url']
$GLOBALS['base_path']
$GLOBALS['theme']
$GLOBALS['locale']

$GLOBALS['multibyte']
$GLOBALS['access_check']
$GLOBALS['pager_page_array']
$GLOBALS['pager_total']

$GLOBALS['form_values']
$GLOBALS['element']
$GLOBALS['item']
$GLOBALS['tag']

That is all. There are also some statics in some scopes.
