scandir --

Descrição
array
scandir ( string directory [, int sorting_order [, resource context]] )
Returns an array of files and directories from the
directory. If directory
is not a directory, then boolean FALSE is returned, and an error of
level E_WARNING is generated.
By default, the sorted order is alphabetical in ascending order. If
the optional sorting_order is used (set to 1),
then sort order is alphabetical in descending order.
For a description of the context parameter, refer
to Referência CXX, Stream Functions.
Exemplo 1. A simple scandir() example
