scandir
List files and directories inside the specified path
(PHP 5)
array scandir ( string directory [, int sorting_order [, resource context]] )
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 510. 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 511. 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
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 O, List of Supported Protocols/Wrappers for a list of supported URL protocols.
