How to check if Zend select returns a result or not

Question

In Zend framework, how do I check if zend_db_select returns a result or not?

$result = $this->fetchAll();

is there a better way rather than using:

if(count($result) != 0){
    //result found!
}

Answer 1

$rows = $this->fetchAll();
return (!empty($rows)) ? $rows : null;

Answer 2

I like to use the classic:

   //most of these queries return either an object (Rowset or Row) or FALSE 
   if (!$result){
        //do some stuff
    } else {
        return $result;
    }

Answer 3

I've found this way and works fine for me :

if($result->count() > 0) {
    //Do something
}
