Re: recursive function not returning anything..

      $query = mysql_query($sql);

         $data = mysql_fetch_array($query);

         $Path[] = $data["Name"];

         recursePathLookup($data["SubCategoryID"], $Path);

change to:

return recursePathLookup($data["SubCategoryID"], $Path);

      } else {

         //print_r($Path);

         return $Path;

      }

} print_r(recursePathLookup(2)); Any ideas why when I uncomment the //print_r($Path) inside the function it prints the value fine, but when I try to return the value and print it outside the function I get nothing? Thanks, Nate
