Array in hashes???? 2

[isodbaar]

hi Guys,
I have an hash that look like this (debug)

x %myhash
0 'ParentFolder'
1 '//server/folder1/'
2 'myarray'
3 ARRAY(0x1f6dc08)
0 'January'
1 'February'
2 'March'
3 'April'
4 'May'
5 'June'
6 'July'
7 'August'
8 'September'
9 'October'
10 'November'
11 'December'

What I want to do is to print the array in the key 'myarray'.
I am trying
foreach ($myhash{'myarray'}) {
print "$_\n";

}

All I get is ARRAY(0x1a59d28).

Thanks!!!

In that case, $_ is a reference to an array.

foreach (@{$myhash{'myarray'}}) {
print "$_\n";
}

That will get you the values of the arrayref.

On this topic though, check out Data:umper.

use Data::Dumper;
print Dumper ($myhash);

Data:umper prints out the data structures of hashes and arrays (and references of each)... yours might look like this:

(
   'ParentFolder' => '//server/folder1',
   'myarray'      => [ # square brackets = arrayref
      'February',
      'March',
      'April',
      'May',
      'June',
      'July',
      'August',
      'September',
      'October',
      'November',
      'December',
   ],
);

Data:umper makes it easy to copy/paste your data structure for posts such as this one to Tek-Tips, rather than the way you wrote it out up there.
