Loading Config Item in Helper - Pls Help

[eluser]Deep Arora[/eluser]
I am trying to load a config item in helper function I am writing as:

Code:

$S3AWSID = $this->config->item('S3_ACCESS_KEY_ID');

But it throws a message as:

Code:

Fatal error: Using $this when not in object context in customer_helper.php on line 28

How can I call and use config params in helper?

Either

Code:

$ci =& get_instance();
$var = $ci->config->item('setting');

or, more simply

Code:

$var = config_item('setting');
