Re: How to compare an empty key with another empty key in associative array

in reply to How to compare an empty key with another empty key in associative array

$b = {}; is not an associative array. An array containing other arrays may look something like this:

my @two_d_array = ([$x,$y,$z],[1,2,3],['a','b','c']);

To see if an array is empty, you can check it's scalar value for contents.

my $elements = scalar(@two_d_array);

UPDATED: Associative array is considered a hash in Perl, (thanks choroba),

    "Associative array" is "hash" in Perl lingo, not an array.
