One last directory function

array scandir ( string dirname [, int sorting_order [, resource context]])

Scandir() is a neat function that takes a minimum of one parameter with an optional second. Parameter one is the path of a directory you want to work with - scandir() returns an array of all files and directories in the directory you specify here. Parameter two, if included and set to 1, will sort the array returned reverse alphabetically - if it is not set, the array is returned sorted alphabetically.

This next script prints out a list of all the files and directories in the current directory, with reverse sorting:

<?php
    $files = scandir(".", 1);
    var_dump($files);
?>

Using scandir() is a quick alternative to calling readdir() repeatedly, and is particularly helpful when you use the second parameter.
