getcwd
Here are two versions of the same function to list all files in a directory tree.
The first one is recursive (calls itself while going through subdirectories) :
<?php
function rec_listFiles( $from = '.')
{
if(! is_dir($from))
return false;
$files = array();
if( $dh = opendir($from))
{
while( false !== ($file = readdir($dh)))
{
// Skip '.' and '..'
if( $file == '.' || $file == '..')
continue;
$path = $from . '/' . $file;
if( is_dir($path) )
$files += rec_listFiles($path);
else
$files[] = $path;
}
closedir($dh);
}
return $files;
}
?>
The second one is iterative (uses less memory) :
<?php
function listFiles( $from = '.')
{
if(! is_dir($from))
return false;
$files = array();
$dirs = array( $from);
while( NULL !== ($dir = array_pop( $dirs)))
{
if( $dh = opendir($dir))
{
while( false !== ($file = readdir($dh)))
{
if( $file == '.' || $file == '..')
continue;
$path = $dir . '/' . $file;
if( is_dir($path))
$dirs[] = $path;
else
$files[] = $path;
}
closedir($dh);
}
}
return $files;
}
?>
The iterative version should be a little faster most of the time, but the big difference is in the memory usage.
Here is also a profiling function (works in php5 only) :
<?php
function profile( $func, $trydir)
{
$mem1 = memory_get_usage();
echo '<pre>-----------------------
Test run for '.$func.'() ...
'; flush();
$time_start = microtime(true);
$list = $func( $trydir);
$time = microtime(true) - $time_start;
echo 'Finished : '.count($list).' files</pre>';
$mem2 = memory_get_peak_usage();
printf( '<pre>Max memory for '.$func.'() : %0.2f kbytes
Running time for '.$func.'() : %0.f s</pre>',
($mem2-$mem1)/1024.0, $time);
return $list;
}
?>
opendir
(PHP 4, PHP 5)
opendir — Open directory handle
Description
resource opendir
( string $path
[, resource $context
] )
Opens up a directory handle to be used in subsequent closedir(), readdir(), and rewinddir() calls.
Parameters
- path
-
The directory path that is to be opened
- context
-
For a description of the context parameter, refer to the streams section of the manual.
Return Values
Returns a directory handle resource on success, or FALSE on failure.
If path is not a valid directory or the directory can not be opened due to permission restrictions or filesystem errors, opendir() returns FALSE and generates a PHP error of level E_WARNING. You can suppress the error output of opendir() by prepending '@' to the front of the function name.
ChangeLog
| Version | Description |
|---|---|
| 5.0.0 | path supports the ftp:// URL wrapper. |
| 4.3.0 | path can also be any URL which supports directory listing, however only the file:// URL wrapper supports this in PHP 4 |
Examples
Example #1 opendir() example
<?php
$dir = "/etc/php5/";
// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
echo "filename: $file : filetype: " . filetype($dir . $file) . "\n";
}
closedir($dh);
}
}
?>
The above example will output something similar to:
filename: . : filetype: dir filename: .. : filetype: dir filename: apache : filetype: dir filename: cgi : filetype: dir filename: cli : filetype: dir

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";

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;

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
files/
num_files.phps
test.php
<?php
function num_files($dir, $type, $ext="")
{
// type 1: files only
// type 2: direcories only
// type 3: files and directories added
// type 4: files and directories separated with a space
if (!isset($dir) OR empty($dir))
{
echo '<b>Syntax error:</b> $dir value empty.';
exit;
}
$num_files = 0;
$num_dirs = 0;
switch($type)
{
case 1: // count only files, not dirs
if ($dir = @opendir($dir))
{
while (($file = readdir($dir)) !== false)
{
if(is_file($file) AND $file != "." AND $file != "..")
{
if (isset($ext) AND !empty($ext))
{
$extension = end(explode(".", $file));
if ($ext == $extension)
{
$num_files++;
}
}
else
{
$num_files++;
}
}
}
closedir($dir);
$total = $num_files;
}
break;
case 2: // count only dirs, not files
if ($dir = @opendir($dir))
{
while (($file = readdir($dir)) !== false)
{
if(is_dir($file) AND $file != "." AND $file != "..")
{
$num_dirs++;
}
}
closedir($dir);
$total = $num_dirs;
}
break;
case 3: // count files PLUS dirs in once variable
if ($dir = @opendir($dir))
{
while (($file = readdir($dir)) !== false)
{
if(is_dir($file) OR is_dir($file))
{
if ($file != "." AND $file != "..")
{
$num_files++;
}
}
}
closedir($dir);
$total = $num_files;
}
break;
case 4: // count files AND dirs separately
if ($dir = @opendir($dir))
{
while (($file = readdir($dir)) !== false)
{
if(is_file($file) AND $file != "." AND $file != "..")
{
$num_files++;
}
if(is_dir($file) AND $file != "." AND $file != "..")
{
$num_dirs++;
}
}
closedir($dir);
$total = $num_files." ".$num_dirs;
}
break;
default:

}
echo num_files($_SERVER['DOCUMENT_ROOT'], 1, "php"). " file(s) met php extention<br /> ";

echo num_files($_SERVER['DOCUMENT_ROOT'], 2). " dir(s)<br />";
echo num_files($_SERVER['DOCUMENT_ROOT'], 3). " file(s) + dir(s)<br />";
$nummers = explode(" ", num_files($_SERVER['DOCUMENT_ROOT'], 4));
echo reset($nummers) ." file(s) en ". end($nummers) ." dir(s)";
?>
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)

$filename = explode(".",$file); //seperate filename from extenstion
$cnt = count($filename); $cnt--; $ext = $filename[$cnt]; //as above

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++;

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.

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));

John & I have edited the code posted by hendrik dot wermer at gmx dot de on 07-Feb-2005 06:06
This Code now allows for downloads form sub directories. We also used CSS to make the page's look customizable.
You can view the example at: http://www.asterikast.com/code/dirlist.txt

In response to previous post,
you can use realpath() to fix the '/../../../' problem.

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!

I Just wanted a directory list and a clickable link to download the files
<snip>

<?
echo ("<h1>Directory Overzicht:</h1>");
function getFiles($path) {
<snip complicated function contents>
------------------------------------------------------------------
Here's a more straightforward way to linkify $path/files:
<?php
echo "<h1>Directory Overzicht:</h1>";
$dh = opendir($path);
while (($file = readdir($dh)) !== false) {
echo "<a href='$path/$file'>$file</a><br />";
}
closedir($dh);
?>

I Just wanted a directory list and a clickable link to download the files because my plesk server does not give me this function. I edited the script a little bit.
Many thanks from a script-noob
