Er, N, it's all in the RTFM.
Start from the inside out...
$_SERVER['PHP_SELF'] contains the path of the current file, from the web
root IIRC, something like
/folder/folder/file.ext
_explode_ this into an array, delimited by /
folder,
folder,
file.ext
_array-pop_ the *last* element in the array
file.ext
explode this on .
file,
ext
_array_shift_ the *first* entry out of this array
file
On looking at the above (written the odd several years ago) I admit the
whole thing should now be shortened into a preg_match() or two. May do that
some day. Then again I now my create menus directly from the database and
the routines that access that database know *exactly* what "page" they are
in and they know *precicely* how to write the HTML that will, in due couse,
be selected by the appropriate CSS rules.

True. Just a different programmers coding expression of the "algorithm".

echo "<ul>\r\n";
menuitem('page1','Page 1');
menuitem('page2','Page 2');
echo "</ul>\r\n";
The expression of function menuitem($page,$text) is up to you :-)
