I usually do this:
<select name="something">
<? foreach($foos as $foo): ?>
<option value="<?=$foo?>" <? selected($val, $foo);
?>><?=$foo?></option>
<? endforeach; ?>
</select>
Where the selected() function echo "selected" if the two parameters are
equal. Doing it this way means I can very easily add in a javascript
handler, add an id, specify a class, add a empty item, and so forth.
The loop structure is also flexible. Sometimes I might use a for() loop
instead.
A function that can handle all the possibilities would be rather
complicated. Chances are you won't remember the parameters. This way,
it's just a matter of knowing your HTML. Friendlier for someone who has
to read your code too.

Do this:
foreach((array) $clowns as $name => $clown) { }
Null converts to an empty array.
