Re^2: hash array by johngg (Canon) on Dec 26, 2006 at 14:53 UTC
I find your example rather misleading as your variable `$HASH` is not referring to a hash structure at all but to an array. You are using `push`, which pushes an element onto the right-hand, or top, end of an array and you are using the `@` sigil to dereference `$HASH` to get at the array it refers to. You say "dump the whole hash" when using `Data::Dumper` but again you are supplying a reference to an array and, by enclosing the argument in anonymous hash constructors `Data::Dumper->Dump([$HASH])`, you are actually going to see an array of arrays in your output. Something like `$VAR1 = [ [ 'data1', 'data2', 'data3' ] ];` [download] Later you loop over the array printing out each element but you confuse things again by referring to each as a key. Arrays don't have keys, hashes do. Also, why do you declare the scalar `$value` then never use it? Cheers, JohnGG	[reply] [d/l] [select]

$HASH

Data::Dumper->Dump([$HASH])

$VAR1 = [
           [
              'data1',
              'data2',
              'data3'
