You want to use the 'defined' function to test if your array contains anything. 'defined' will return true if the array has any elements, and will return false if it is A: not defined at all, or B: defined null (@arr = () returns false). 
my @one = ('A', 'B', 'C');
my @two = ();
if (defined(@one))
 {
   print "Array one is defined.\n";
 }
if (defined(@two))
 {
   print "Array two is defined.\n";
 }

will print only: 
Array one is defined.
