Would you like to view your directories in your browser this script might come in handy.
<?php
$sub = ($_GET['dir']);
$path = 'enter/your/directory/here/';
$path = $path . "$sub";
$dh = opendir($path);
$i=1;
while (($file = readdir($dh)) !== false) {
if($file != "." && $file != "..") {
if (substr($file, -4, -3) =="."){
echo "$i. $file <br />";
}else{
echo "$i. <a href='?dir=$sub/$file'>$file</a><br />";
}
$i++;
}
}
closedir($dh);
?>
opendir
(PHP 4, PHP 5)
opendir — Ouvre un dossier, et récupère un pointeur dessus
Description
resource opendir
( string $path
[, resource $context
] )
opendir() retourne un pointeur sur un dossier qui pour être utilisé avec les fonctions closedir(), readdir() et rewinddir().
Liste de paramètres
- path
-
Le chemin du répertoire à ouvrir
- context
-
Pour la description du paramètre context , référez-vous à la section des flux du manuel.
Valeurs de retour
Retourne la ressource de dossier en cas de succès ou FALSE en cas d'échec.
Si le paramètre path n'est pas un dossier valide, ou si le dossier ne peut être accédé pour des raisons de permissions ou des erreurs liées au système de fichiers, opendir() retourne FALSE et génère une erreur PHP de niveau E_WARNING. Vous pouvez supprimer cette erreur en ajoutant '@' avant le nom de la fonction.
Historique
| Version | Description |
|---|---|
| 5.0.0 | path supporte l'enveloppe URL ftp:// |
| 4.3.0 | path peut aussi être n'importe quel URL qui supporte le listage de dossiers, par contre, seul l'enveloppe URL file:// supporte ceci en PHP 4. |
Exemples
Exemple #1 Exemple avec opendir()
<?php
$dir = "/tmp/php5";
// Ouvre un dossier bien connu, et liste tous les fichiers
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
echo "fichier : $file : type : " . filetype($dir . $file) . "\n";
}
closedir($dh);
}
}
?>
L'exemple ci-dessus va afficher quelque chose de similaire à :
fichier : . : type : dir fichier : .. : type : dir fichier : apache : type : dir fichier : cgi : type : dir fichier : cli : type : dir

I was trying to access network drives using this opendir function. I read so many posts saying that it was almost impossible to access a network drive and finally, I found the answer; there are 2 steps to be followed to access a network drive with PHP either on the same machine or another machine.
But first of all, here's the error I was getting:
Warning: opendir(\\server\folder1\sub_folder) [function.opendir]: failed to open dir: No error in C:\wamp\www\PMOT\v0.1\REPORT_MENU\index.php on line 17
Firstly, one must make sure that the folder \\server\folder1\sub_folder can be accessed by a user, let's say USER_TEST with a password PASS_TEST. By setting properties to this folder, one can add this given user with the correct password (USER_TEST with PASS_TEST).
Secondly, the APACHE service must be set-up to take this user into account. If no user is specified, APACHE uses an anonymous user and this is where the problem/error message is coming from. One must go in control panel->administrative tools->services. One will see the list of services and must look for APACHE with Apache/2.X.X in the description. (For Wampserver, it will be called wampapache, and so on!) Right click on that and pop up the properties screen. In the tab LOG ON, there are 2 options: local system account and "this account" which will be a user specified account. This is where one must specify the USER_TEST and PASS_TEST.
Following these steps worked perfectly for me but if either the folder privileges or apache log on user is disabled, then I get the initial aforementioned error message.
Anyways, I hope this can help out someone!
Cheers!

An other way to recursively walk a directory and it's content, applying a callback to each file.
Exemple: Update the last modification time of each file in a folder
<?php
clearstatcache();
$sourcepath = "C:/WINDOWS/TEMP";
// Replace \ by / and remove the final / if any
$root = ereg_replace( "/$", "", ereg_replace( "[\\]", "/", $sourcepath ));
// Touch all the files from the $root directory
if( false === m_walk_dir( $root, "m_touch_file", true )) {
echo "'{$root}' is not a valid directory\n";
}
// Walk a directory recursivelly, and apply a callback on each file
function m_walk_dir( $root, $callback, $recursive = true ) {
$dh = @opendir( $root );
if( false === $dh ) {
return false;
}
while( $file = readdir( $dh )) {
if( "." == $file || ".." == $file ){
continue;
}
call_user_func( $callback, "{$root}/{$file}" );
if( false !== $recursive && is_dir( "{$root}/{$file}" )) {
m_walk_dir( "{$root}/{$file}", $callback, $recursive );
}
}
closedir( $dh );
return true;
}
// if the path indicates a file, run touch() on it
function m_touch_file( $path ) {
echo $path . "\n";
if( !is_dir( $path )) {
touch( $path );

A simple function to count all the files and/or dirs inside a dir.
With optional extention when counting files.
Index of /
Some text file.txt

<?php
function num_files($dir, $type, $ext="")

?>
will output:
1 file(s) with php extention
3 file(s)
1 dir(s)
1 file(s) + dir(s)
3 file(s) en 1 dir(s)

In reponse to Tozeiler. Nice short directory dump. However, that displays the "." and "..". This removes those. It also makes an ordered list in case I needed to be on the phone while looking at the page. Easy to call out.
<?php
$path = "your path";
$dh = opendir($path);
$i=1;
while (($file = readdir($dh)) !== false) {
if($file != "." && $file != "..") {
echo "$i. <a href='$path/$file'>$file</a><br />";
$i++;
}
}
closedir($dh);

Using Apache 2.2.4 with PHP and MySQL I was trying to connect to a Novell Netware drive using opendir("R:/") where R: was pointing to a Netware resource on another server. The error returned was
Warning: opendir(R:/) [function.opendir]: failed to open dir: No such file or directory in path/to/my/phpfile/containing/opendir on line 34.
Basically it is a problem with Netware rights and users and how the apache service was trying to connect to the resource.
To get everything working as expected in the end we set up a Windows user account eg: webhost with the same password as a Netware account with username webhost, set the Netware account to have rights to the resource R:/ (we just used admin rights), and set the apache service to run as the webhost user using the username password combo.
Hope this helps someone else out.

This is a script that prints all the file and directory names on your server no matter where the script file is located
(could take a lot of time to execute, if you have a lot of directories and files...)
Hope someone finds it useful...

$root = @opendir($_SERVER['DOCUMENT_ROOT']);
$dirs = array();
while($file = readdir($root)){

$dirs[] = ($_SERVER['DOCUMENT_ROOT'] . "/" . $file);
print "(adding directory)";
}
print "<br />";
}
closedir($root);
print "<br /><br />Inside Dirs: (" . (count($dirs)) . ")<br />";
$i = 0;
while($i < count($dirs)){

Here's a function that will recrusively turn a directory into a hash of directory hashes and file arrays, automatically ignoring "dot" files.
<?php
function hashify_directory($topdir, &$list, $ignoredDirectories=array()) {
if (is_dir($topdir)) {
if ($dh = opendir($topdir)) {
while (($file = readdir($dh)) !== false) {
if (!(array_search($file,$ignoredDirectories) > -1) && preg_match('/^\./', $file) == 0) {
if (is_dir("$topdir$file")) {
if(!isset($list[$file])) {
$list[$file] = array();
}
ksort($list);
hashify_directory("$topdir$file/", $list[$file]);
} else {
array_push($list, $file);
}
}
}
closedir($dh);
}
}
}
?>
e.g.
<?php
$public_html["StudentFiles"] = array();
hashify_directory("StudentFiles/", $public_html["StudentFiles"]);
?>
on the directory structure:
./StudentFiles/tutorial_01/case1/file1.html
./StudentFiles/tutorial_01/case1/file2.html
./StudentFiles/tutorial_02/case1/file1.html
./StudentFiles/tutorial_02/case2/file2.html
./StudentFiles/tutorial_03/case1/file2.html
etc...
becomes:
<?php
print_r($public_html);
/*
outputs:
array(
"StudentFiles" => array (
"tutorial_01" => array (
"case1" => array( "file1.html", "file2.html")
),
"tutorial_02" => array (
"case1" => array( "file1.html"),
"case2" => array( "file2.html")
),
"tutorial_03" => array (
"case1" => array( "file2.html")
)
)
)
*/
?>

An issue that I ran into is that opendir() could care less if you've got server authentication set on sub directories and so any such authentication is bypassed completely when accesses in this way. I did solve it for my application of a pretty file manager, by redirecting to all sub directories thusly:
$fdir = "./subdirectory_I_want_to_visit/";
if ($fdir != './') { //basically where we are or the parent
//redirect the browser to force authentication check on any subdirectories
header("Location: http://my.domain.com".dirname($_SERVER["PHP_SELF"]).substr($fdir,2));
exit;
} else {
$dir = opendir($fdir);

Pointing on the previous post, I'd like to say the following.
You can use opendir on all valid (existant and reachable) folders.
This counts not only for windows but also for linux.
Under linux, you can also read root folders etc.
To avoid access to non-public data, you should check the given parameter for opendir before executing opendir.
Let's say you have this:
/home/users/mrsmith/
/home/users/mrsmith/info.txt
/home/users/mrsmith/test/photo.jpg
/home/users/mradmin/private.txt
Now you don't want mrsmith to access mradmin's folders/files.
In that case you could/should define the path where the data MUST be inside.
Attention:
Don't check the data with substr though, it's not a secure solution.
Exploit example: /home/users/mrsmith/../mradmin/
Exploit example2: /home/users/mrsmith/../../../../../../../../../../../../../dev/
I'd do a case sensitive regex match.
So after the first folder there may not be a subfolder named ".." because that would jump one folder back.
I hope this isn't too offtopic or so but I think it's important to think of that when creating file systems.

Hello,
A friend of mine is running a webhost, I think i found a security leak with this script:
<?php
function select_files($dir, $label = "", $select_name, $curr_val = "", $char_length = 30) {
$teller = 0;
if ($handle = opendir($dir)) {
$mydir = ($label != "") ? "<label for=\"".$select_name."\">".$label."</label>\n" : "";
$mydir .= "<select name=\"".$select_name."\">\n";
$curr_val = (isset($_REQUEST[$select_name])) ? $_REQUEST[$select_name] : $curr_val;
$mydir .= ($curr_val == "") ? " <option value=\"\" selected>...\n" : "<option value=\"\">...\n";
while (false !== ($file = readdir($handle))) {
$files[] = $file;
}
closedir($handle);
sort($files);
foreach ($files as $val) {
if (is_file($dir.$val)) { // show only real files (ver. 1.01)
$mydir .= " <option value=\"".$val."\"";
$mydir .= ($val == $curr_val) ? " selected>" : ">";
$mydir .= (strlen($val) > $char_length) ? substr($val, 0, $char_length)."...\n" : $val."\n";
$teller++;
}
}
$mydir .= "</select>";
}
if ($teller == 0) {
$mydir = "No files!";
} else {
return $mydir;
}
}
echo select_files("C:/winnt/", "", "", "", "60");
?>
Now i can see hist files in his windows dir. Is this a leak? and is it fixable? I'll report this as bug too!

In my previous post I ran into a problem with the "global" definition of $directorylist. If I called the function more than once on the same page it would combine the file lists. I looked at Lasse Dalegaard's example and used the following solution.
remove global definition
global $directorylist;
REPLACE
<?
if ((($maxlevel) == "all") or ($maxlevel > $level)) {
filelist($startdir . $file . "/", $searchSubdirs, $directoriesonly, $maxlevel, $level + 1);
}
?>
WITH
<?
if ((($maxlevel) == "all") or ($maxlevel > $level)) {
$list2 = filelist($startdir . $file . "/", $searchSubdirs, $directoriesonly, $maxlevel, $level + 1);
if(is_array($list2)) {
$directorylist = array_merge($directorylist, $list2);
}
}
?>

I wrote a function to recursively delete files from a starting directory. I had to do this because my server doesn't allow me to delete files that apache writes because I don't have permissions, so... I let apache do the work.
<?php
$dir = "/path/to/base/dir";
recursive_delete($dir);
function recursive_delete( $dir )
{
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false ) {
if( $file != "." && $file != ".." )
{
if( is_dir( $dir . $file ) )
{
echo "Entering Directory: $dir$file<br/>";
recursive_delete( $dir . $file . "/" );
echo "Removing Directory: $dir$file<br/><br/>";
rmdir( $dir . $file );
}
else
{
echo "Deleting file: $dir$file<br/>";
unlink( $dir . $file );
}
}
}
closedir($dh);
}
}
}
?>

oryan's example is still sub-optimal, even if people using it never ever substitute a variable for directory.
Just use PHP's glob() function, which will be faster and more efficient anyway since it doesn't have to launch a shell and run the ls program (that's what the shell_exec does).
$result = glob("directory/*");

There might be a bit of truth to that. If, by chance, the webmaster made a form saying "type a random directory name here" and used that in the function, there'd be a problem. So let's eliminate the 'function' part
$files=shell_exec("ls directory");
$result=explode("\n",$files);
'$result' will now be an array of the directory files. You can use variables in the shell_exec command, but don't use anything that could be user-sent.

The example given by oryan at zareste dot com may also be a "simpler faster way" of creating security holes in your code. The function listed above prevents risking execution of abitrary shell commands listed after a semicolon (;) in your directory name.
Example: $directory = '.;rm -rf /';
Result: List this directory, erase contents of filesystem.

There's a simpler faster way to get a whole directory if you're using PHP 4. This function uses shell_exec - http://us3.php.net/shell_exec - and assumes you're using Unix/Linux and have shell access -
function dir($directory){
$files=shell_exec("ls ".$directory);
return explode("\n",$files);
}
This returns an array with all the files.
This way, you can use modifiers like -t, which shows files in order of modification time ($files=shell_exec("ls -t ".$directory);). Enough tweaking and you can use it on Windows, though I can't say how since I don't have a Windows server to try it on

This function sorts files by name as strings, but without regard to case. It also does some handy string formatting of the file size information.
<?
function getFiles($path) {
//Function takes a path, and returns a numerically indexed array of associative arrays containing file information,
//sorted by the file name (case insensitive). If two files are identical when compared without case, they will sort
//relative to each other in the order presented by readdir()
$files = array();
$fileNames = array();
$i = 0;
if (is_dir($path)) {
if ($dh = opendir($path)) {
while (($file = readdir($dh)) !== false) {
if ($file == "." || $file == "..") continue;
$fullpath = $path . "/" . $file;
$fkey = strtolower($file);
while (array_key_exists($fkey,$fileNames)) $fkey .= " ";
$a = stat($fullpath);
$files[$fkey]['size'] = $a['size'];
if ($a['size'] == 0) $files[$fkey]['sizetext'] = "-";
else if ($a['size'] > 1024) $files[$fkey]['sizetext'] = (ceil($a['size']/1024*100)/100) . " K";
else if ($a['size'] > 1024*1024) $files[$fkey]['sizetext'] = (ceil($a['size']/(1024*1024)*100)/100) . " Mb";
else $files[$fkey]['sizetext'] = $a['size'] . " bytes";
$files[$fkey]['name'] = $file;
$files[$fkey]['type'] = filetype($fullpath);
$fileNames[$i++] = $fkey;
}
closedir($dh);
} else die ("Cannot open directory: $path");

I made a function for finding all files in a specified directory and all subdirectories. It can be quite usefull when searching in alot of files in alot subdirectories. The function returns an array with the path of all the files found.
<?
function getFiles($directory) {
// Try to open the directory
if($dir = opendir($directory)) {
// Create an array for all files found
$tmp = Array();
// Add the files
while($file = readdir($dir)) {
// Make sure the file exists
if($file != "." && $file != ".." && $file[0] != '.') {
// If it's a directiry, list all files within it
if(is_dir($directory . "/" . $file)) {
$tmp2 = getFiles($directory . "/" . $file);
if(is_array($tmp2)) {
$tmp = array_merge($tmp, $tmp2);
}
} else {
array_push($tmp, $directory . "/" . $file);
