It's called the 'ternary operator' (taking three arguments and stuff).. and
I believe it is the only ternary operator at least in PHP.

It's short circuit IF (I believe that's the right word for it). This is the
same
thing as doing this:
if( $r < 1 ) {
$r = $config['maxResults'];
} else {
$r = $r;
}
