$output_fname = (isset($HTTP_POST_VARS['fname'])) ? $HTTP_POST_VARS['fname']
: '';
but the value WILL be set regardless... in this case i'd prefer:
if(isset($HTTP_POST_VARS['fname'])) { $output_fname =
$HTTP_POST_VARS['fname']; }
alternatively, I wrote a nice function to pluck out $_POST vars only if
they're set. you could easily modify it to do $HTTP_POST_VARS instead of
$_POST
