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.
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] => . ) |

Tip: You can use a URL as a filename with this function if the fopen wrappers have been enabled. See fopen() for more details on how to specify the filename and Appendix J for a list of supported URL protocols.
