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 L for a list of supported
URL protocols.
