Change folder to fetch on filemanager - php

Question

I've the following problem: i'm working on a filemanager consisting in only one index.php file, that fetches all the files and folders from the actual folder there its located in.
So if i have a folder with the filemanager file on it:
Folder01
-folder-A
-folder-B
-file1.php
-image.png
-index.php
The filemanager will show: folder-A, folder-B, file1.php and image.png
The problem is I can't change the folder to fetch it's content, to be able to view, by default, the content of folder-A for example.
$file = isset($_REQUEST['file']) ? urldecode($_REQUEST['file']) : '.';
if(isset($_GET['do']) && $_GET['do'] == 'list') {
if (is_dir($file)) {
$directory = $file;
$result = array();
$files = array_diff(scandir($directory), array('.','..'));
foreach($files as $entry) if($entry !== basename(__FILE__)) {
$i = $directory . '/' . $entry;
$stat = stat($i);
$result[] = array(
'mtime' => $stat['mtime'],
'size' => $stat['size'],
'name' => basename($i),
'path' => preg_replace('#^\./#', '', $i),
'ext' => pathinfo($i, PATHINFO_EXTENSION),
'is_dir' => is_dir($i),
'is_deleteable' => (!is_dir($i) && is_writable($directory)) ||
(is_dir($i) && is_writable($directory) && is_recursively_deleteable($i)),
'is_readable' => is_readable($i),
'is_writable' => is_writable($i),
'is_executable' => is_executable($i),
);
}
} else {
err(412,"Not a Directory");
}
echo json_encode(array('success' => true, 'is_writable' => is_writable($file), 'results' =>$result));
exit;
}
This snippet is the beginning of its php code, which is in charge of fetching the files of the selected folder.
Any idea about how to change that?

Answer 1

try glob function, its like dir command in dos,
it will list all of the dirs and files in the current working directory and put them in an array, which is the return value of the function.
