Directory Listing with Pagination
Thu, 2008/03/13 - 05:48 — Jamie
This script is a directory lister that shows whatever files you want using the glob PHP function. It can be configured to show as many or as little files per page are you want. You can also exclude certain directories of your choice. The pagination part perhaps needs a little attention but you should be able to work thing out OK.

//~ disallow browsing of certain directories (lowercase!!)

'private',
