You don't really need to check the length if all you want to know is if the array has something in it or not, you can just use "if" with "!" to see if it does:

Expand|Select|Wrap|Line Numbers
  1. @array = ();
  2. $array_ref = \@array;
  3. if (! @{$array_ref}) {
  4.    print "Empty";
  5. };
Note you do have to dereference the array reference to check its status (empty or not).
