How do you use get_filenames or directory_map in codeigniter?

I'm new to codeigniter and php and am having a really hard time figuring out some of the helpers that don't include examples!

Can someone provide a few lines of code that would show how to use get_filenames or directory_map to echo the list of files in a specific folder?  No need to worry about subfolders as what I'm doing will not have any subfolders, only files.

you can use get_filenames function as following :-

NOTE: your apache user has to have  read access in the target directory.

Regarding  directory_map, its well explained in there documentation:-

$data = get_filenames('/var/www/html/');
