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.
Parameters
- directory
The directory that will be scanned.
- sorting_order
By default, the sorted order is alphabetical in ascending order. If
the optional sorting_order is used (set to 1),
then the sort order is alphabetical in descending order.
- context
For a description of the context parameter,
refer to the streams section of
the manual.
Return Values

failure. If directory is not a directory, then
boolean FALSE is returned, and an error of level
E_WARNING is generated.
Examples
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

[3] => ..
[4] => .

$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] => .

[3] => foo.txt
[4] => somedir
)
Array

filename with this function if the fopen wrappers have been enabled.
See fopen() for more details on how to specify
the filename and Appendix M for a list of supported
