In PHP, how can I get the URL of the current page? Preferably just the parts after http://domain.com.

$_SERVER['REQUEST_URI']
For more details on what info is available in the $_SERVER array, see the PHP manual page for it.
If you also need the query string (the bit after the ? in a URL), that part is in this variable:
$_SERVER['QUERY_STRING']
if you want just the parts of url after http://domain.com, try this:
<?php echo $_SERVER['REQUEST_URI']; ?>
if the current url was http://domain.com/some-slug/some-id, echo will return only '/some-slug/some-id'.
if you want the full url, try this:
<?php echo 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; ?>
$uri = $_SERVER['REQUEST_URI'];
This will give you the requested directory and file name. If you use mod_rewrite, this is extremely useful because it tells you what page the user was looking at.
If you need the actual file name, you might want to try either $_SERVER['PHP_SELF'], the magic constant __FILE__, or $_SERVER['SCRIPT_FILENAME']. The latter 2 give you the complete path (from the root of the server), rather than just the root of your website. They are useful for includes and such.
$_SERVER['PHP_SELF'] gives you the file name relative to the root of the website.
$relative_path = $_SERVER['PHP_SELF'];
$complete_path = __FILE__;
$complete_path = $_SERVER['SCRIPT_FILENAME'];
