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

Returns an array of filenames on success, or FALSE on 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 [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

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 M for a list of supported URL protocols.
