SCANDIR_SORT_DESCENDING
, then the sort order is
alphabetical in descending order. If it is set to
SCANDIR_SORT_NONE
then the result is unsorted.

parameter,
refer to the streams section of
the manual.

on
failure. If directory
is not a directory, then
boolean FALSE

E_WARNING
is generated.

Example #1 A simple scandir() example
<?php
$dir = '/tmp';
$files1 = scandir($dir);
$files2 = scandir($dir, 1);
print_r($files1);
print_r($files2);
?>
The above example will output something similar to:
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);
?>
The above example will output something similar to:
Array ( [0] => . [1] => .. [2] => bar.php [3] => foo.txt [4] => somedir ) Array ( [0] => somedir [1] => foo.txt [2] => bar.php [3] => .. [4] => . )
A URL can be used as a filename with this function if the fopen wrappers have been enabled. See fopen() for more details on how to specify the filename. See the Supported Protocols and Wrappers for links to information about what abilities the various wrappers have, notes on their usage, and information on any predefined variables they may provide.
