Accessing config file arrays

[eluser]Unknown[/eluser]
Hi!

I'm interested, is there a method to simplify accessing an array inside a config file.

my_config.php:

Code:

$config['my_array'] = array(
   'key1' => 'value1',
   'key1' => 'value2'
);

Works:

Code:

$this->config->load('my_config');
$values = $this->config->item('my_array');
echo $values['key1'];

Doesn't work:

Code:

$this->config->load('my_config');
echo $this->config->item('my_array')['key1'];

Question is - is it possible to make it work (what changes do i need to do) ??

Sorry, for my english ,
Thanks !
