Parameters
- directory

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] => . )
Notes
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.
