so i do eager loading and it returned 1 array inside array like this

array(3) {
  [0]=>
  array(6) {
    ["id"]=>
    int(5)
    ["name"]=>
    string(20) "Berita Internasional"
    ["jumlah"]=>
    int(0)
    ["created_at"]=>
    string(20) "-0001-11-30 00:00:00"
    ["updated_at"]=>
    string(19) "2014-10-30 03:14:04"
    ["artikel"]=>
    array(0) {
    }
  }
  [1]=>
  array(6) {
    ["id"]=>
    int(6)
    ["name"]=>
    string(16) "Berita Teknologi"
    ["jumlah"]=>
    int(0)
    ["created_at"]=>
    string(20) "-0001-11-30 00:00:00"
    ["updated_at"]=>
    string(19) "2014-11-05 07:29:47"
    ["artikel"]=>
    array(0) {
    }
  }
  [2]=>
  array(6) {
    ["id"]=>
    int(7)
    ["name"]=>
    string(14) "Berita Ekonomi"
    ["jumlah"]=>
    int(2)
    ["created_at"]=>
    string(20) "-0001-11-30 00:00:00"
    ["updated_at"]=>
    string(20) "-0001-11-30 00:00:00"
    ["artikel"]=>
    array(0) {
    }
  }
}

so as you can see ["artikel"] is containing array (althougth in this code example i make it empty for easy read but i will contain something)

how to echo out ["artikel"] part for each array?
