[Basic PHP] Treat function or method call as an array?

[eluser]danmontgomery[/eluser]
Like the stack overflow post says, you can't treat return values as arrays. You can get rid of one of your lines, though.

Code:

$array = $CI->config->item('returns_indexed_array');
$value = $array[$CI->config->item('returns_index')];

You could also just write a helper function so that it would at least look cleaner.
