in reply to Get one element from anonymous hash

print "$$data{'firstname'}\n";

Likely you want print "$data[0]{'firstname'}\n"; or what ever array index you need. 

for my $i (0 .. $#data) {
    print $data[$i]{firstname}, "\n";    
}

    What if I need to add an element to it?

      You have an "Array of hash-refs" - usually referred to as AOH.

      Adding data is like adding to the end of an array: 

      push @data,
  {
'firstname' => 'Suzy',
 'lastname' => 'Wong',
 'id' => '5253',
 'email' => 'test2@test.com',
'date' => '04/03/2014',
 'olddate' => '04-23-2013',
 'page' => 'no page',
 };
