scandir

Description

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.

Example 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] => . ) */ ?>

Example 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] => . ) */ ?>
