I've always done it like this:

$count = mysql_num_rows( $result );
if( $count == 0 ) then doomething();

But there may be a better way..

In yours it appears you are testing for anything in mysql_num_rows($result)
and a value of 0 in mysql_num_rows($ret). I may be misundertanding you. Do
you mean to test for the value of both to be 0? If that's the case, I was
under the impression that it would have to be if( $foo == 0 AND $bar == 0 )
then doSomething(); but I could be wrong..

Later,
