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.

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     [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 and List of Supported Protocols/Wrappers for a list of supported URL protocols.
