# scandir

(PHP 5)

scandir -- List files and directories inside the specified path

## Description

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.

Exemplo 1. A simple scandir() example
`<?php $dir = '/tmp'; $files1 = scandir($dir); $files2 = scandir($dir, 1); print_r($files1); print_r($files2); ?>`
Outputs something like:
    Array
    (
        [0] => .
        [1] => ..
        [2] => bar.php
        [3] => foo.txt
        [4] => somedir
    )
    Array
    (
        [0] => somedir
        [1] => foo.txt
        [2] => bar.php
        [3] => ..
        [4] => .
    )

Exemplo 2. PHP 4 alternatives to scandir()
`<?php $dir = "/tmp"; $dh = opendir($dir); while (false !== ($filename = readdir($dh))) { $files[] = $filename; } sort($files); print_r($files); rsort($files); print_r($files); ?>`
Outputs something like:
    Array
    (
        [0] => .
        [1] => ..
        [2] => bar.php
        [3] => foo.txt
        [4] => somedir
    )
    Array
    (
        [0] => somedir
        [1] => foo.txt
        [2] => bar.php
        [3] => ..
        [4] => .
    )

> Dica: Você pode usar uma URL com esta função se fopen wrappers estiver habilitado. Veja fopen() para mais detalhes em como especificar o nome do arquivo e Apêndice L para uma lista de protocolos URL suportados.
