Check the PHP documentation about the end() function: http://php.net/manual/en/function.end.php
Quoting the parameters section:
Quote:array
The array. This array is passed by reference because it is modified by the function. This means you must pass it a real variable and not a function returning an array because only actual variables may be passed by reference.
Try this:
PHP Code:
$segments = $this->uri->segment_array();
$section = end($segments);
