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.

Exempel

Exempel 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] => .
)

Exempel 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] => .
)
