How do I call a function in a library from another function in that same library? I have my $CI =& get_instance(); and the function I want to call is say test(). Ive tried calling it via test(), $this->test(), $CI->test(), $CI->lib_name->test() ...
?

That gives a Call to undefined function error.

Then you're doing something else wrong, post some code.

Code:
class my_lib {
function get_locations($location, $filter_array){
...
$nbr_matches = $this->count_key($test, 'full-name');
...
}
function count_key($array, $key) {
$count = 0;
foreach($array as $k => $val) {
if($k == $key)
$count++;
if(is_array($val))
$count += count_key($val, $key);
}
return $count;
}

Great catch, thanks. I was looking at the wrong line number.
