Examples

Example #1 A simple scandir() example

<?php
$dir    
'/tmp';
$files1 scandir($dir);
$files2 scandir($dir1);

print_r($files1);
print_r($files2);
?>

The above example will output something similar to:

$files[] = $filename;
}

sort($files);

print_r($files);

rsort($files);

print_r($files);

Notes

Tip

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.
