rewinddir
If I'm remembering my CS classes right... this would be the 'bare bones' recursive method to extract directories and files...
<?php
function getDirectoryTree( $outerDir ){
$dirs = array_diff( scandir( $outerDir ), Array( ".", ".." ) );
$dir_array = Array();
foreach( $dirs as $d ){
if( is_dir($outerDir."/".$d) ) $dir_array[ $d ] = getDirectoryTree( $outerDir."/".$d );
else $dir_array[ $d ] = $d;
}
return $dir_array;
}
?>
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.
Examples
Example #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] => . )
Example #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] => . )
Notes
Tip
A URL can be used 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 List of Supported Protocols/Wrappers for a list of supported URL protocols.

Here is a function that parses your website's directory tree, similar to the scanDirectories function provided by fatpratmatt. However, this allows you to filter out all files except for those with specific extensions, in addition to allowing you to ignore entire directories, and also has a list of specific files to ignore. One last addition is that it allows you to use a regular expression to ignore another set of files.
I use this to walk the directory structure of my website, and to generate a sitemap.xml for Google sitemaps to index my site. This allows me to skip dev, data, library, etc. folders, and files that are not front end files.
The way it's written means you don't need to worry about excluding specific files at all unless they have the extension you are looking for (i.e. html or php files).
Enjoy.
<?php
function get_files($root_dir, $all_data=array())
{
// only include files with these extensions
$allow_extensions = array("php", "html");
// make any specific files you wish to be excluded
$ignore_files = array("gdform.php","fishheader.php","fishfooter.php",
"sitelinks.php","google204accd1c3ac0501.html","sitemapxml.php",
"rotate.php", "fishstockingreport2.php", "repcentral.php", "repne.php",
"repnorth.php","reppowell.php","repse.php","repsouth.php","repse.php",
"stockreplib.php","iestyles.php");
$ignore_regex = '/^_/';
// skip these directories
$ignore_dirs = array(".", "..", "images", "dev", "lib", "data", "osh", "fiq", "google",
"stats", "_db_backups", "maps", "php_uploads", "test");
// run through content of root directory
$dir_content = scandir($root_dir);
foreach($dir_content as $key => $content)
{
$path = $root_dir.'/'.$content;
if(is_file($path) && is_readable($path))
{
// skip ignored files
if(!in_array($content, $ignore_files))
{
if (preg_match($ignore_regex,$content) == 0)
{
$content_chunks = explode(".",$content);
$ext = $content_chunks[count($content_chunks) - 1];
// only include files with desired extensions
if (in_array($ext, $allow_extensions))
{
// save file name with path
$all_data[] = $path;
}
}
}
}
// if content is a directory and readable, add path and name
elseif(is_dir($path) && is_readable($path))
{
// skip any ignored dirs
if(!in_array($content, $ignore_dirs))
{
// recursive callback to open new directory
$all_data = get_files($path, $all_data);
}
}
} // end foreach
return $all_data;
} // end get_files()

Back in the saddle of scandir I wrote this function for a function that I needed to seperate directories from files. Since I am still learning from my last example way below I would figure I would add it so it can be criticized.
<?php
function dirlist($dir, $bool = "dirs"){
$truedir = $dir;
$dir = scandir($dir);
if($bool == "files"){ // dynamic function based on second pram
$direct = 'is_dir';
}elseif($bool == "dirs"){
$direct = 'is_file';
}
foreach($dir as $k => $v){
if(($direct($truedir.$dir[$k])) || $dir[$k] == '.' || $dir[$k] == '..' ){
unset($dir[$k]);
}
}
$dir = array_values($dir);
return $dir;
}
?>
<?php
print_r(dirlist("../")); //confirm array of subdirectories
print_r(dirlist("../", "files") // confirm list on files in the directory
?>

Some modifications of Daniel's code:
the task before me had such a requirement - to show the folder structure in array as follows
[0] => array
{
[name]=>'smth',
[path] =>'smth',
[sub] => array

[1] =>
...
}
}
[1] => array
{
[name]=>'smth',
[path] =>'smth',
[sub] => array
{
[0] =>
[1] =>
...
}
}
...
All the structure will be deposited in $allData array
<?php
/**

* @param array $allowext allowed extensions
* @param array $notallownames not allowed names

recursive callback "scanDirectories" did not work for me. So I changed it to:
function scanDirectories($rootDir, $allowext, &$allData = array()) {
$dirContent = scandir($rootDir);
foreach($dirContent as $key => $content) {
if ($content == '.' || $content == '..') continue;
$path = $rootDir . DIRECTORY_SEPARATOR . $content;
$ext = substr($content, strrpos($content, '.') + 1);
if(in_array($ext, $allowext) && is_file($path) && is_readable($path)) {
$allData[] = $path;
}
else if(is_dir($path) && is_readable($path)) {
// recursive callback to open new directory
scanDirectories($path, $allowext, $allData);
}
// else unreadable hell
}
return $allData;

Just noticed a minor difference between scandir and readdir.
When opening a directory and using readdir(), each file appears to be accessed in the process. This resets the "Last Accessed" time that you would get with fileatime().
With scandir(), the list is created and none of the files are accessed. Therefore the access times remain unchanged.
I encountered this while writing a script to scan a directory and delete any file that hadn't been accessed in x time. Kind of defeated the purpose when the directory listing accessed every file...

This function generates a list of all files in the chosen directory and all subdirectories, throws them into a NON-multidimentional array and returns them.
Most of the recursive functions on this page only return a multi-dimensional array.
This is actually a modification of some one else's function (thanks mail at bartrail dot de ;])
<?php
function scanDirectories($rootDir, $allData=array()) {
// set filenames invisible if you want
$invisibleFileNames = array(".", "..", ".htaccess", ".htpasswd");
// run through content of root directory
$dirContent = scandir($rootDir);
foreach($dirContent as $key => $content) {
// filter all files not accessible
$path = $rootDir.'/'.$content;
if(!in_array($content, $invisibleFileNames)) {
// if content is file & readable, add to array
if(is_file($path) && is_readable($path)) {
// save file name with path
$allData[] = $path;
// if content is a directory and readable, add path and name
}elseif(is_dir($path) && is_readable($path)) {
// recursive callback to open new directory
$allData = scanDirectories($path, $allData);
}
}
}
return $allData;
}
?>
Example output:
print_r(scanDirectories("www"));

Since scandir() returns and array, here is a more concise method of dealing with the '.' and '..' problem when listing directories:
$target = '/';
$weeds = array('.', '..');
$directories = array_diff(scandir($target), $weeds);
foreach($directories as $value)
{
if(is_dir($target.$value))
{
echo $value.'<br />';
}

Bear in mind that sorting is *always* performed when scandir() is called. String sorting takes O(|s|n log n) runtime, and this adds to the burden of the server's memory and processing power.
Therefore, whenever the alphabetical order of the directory content is unimportant, especially if sorting is to be performed by another order, or the natural order of the files on the filesystem is to be utilized, the use of opendir(), readdir() and closedir() combined is always preferred to scandir().

Saw banzai monkeys code and tweaked it a little. I don't have scandir. So I had to play with the suggested use for php4.
Pretty new to PHP so beer with me. This will show your current directory as a link called "Back" and will list all of your files in a menu. I wanted this because I have a lot of static pages and needed a menu that would auto update every time I added a file.
<?php
$current=getcwd();
$directory=basename($current);
$direct=str_replace('-',' ',$directory);
$directoryuppercasewords=ucwords($direct);
/*this first section above will get your current folder or directory and since I have a "-" between the words of my file I have to strip them to look good if I want to show the current folder or directory in the title of the first link
*/
$dir = '.';
$dh = opendir($dir);
while (false !== ($filename = readdir($dh))) {
$files[] =$filename;
}
$t=array_slice($files,2);
$f=array_search('index.php',$t);
/*this code above with the variable $t gets rid of the '.' and the '..' parent and ancestor files. And the variable $f finds the index file and with the code below 'unset' let you use $f as the key to get rid of that file.
*/
unset($t[$f]);
print('<ul align="left">');
print('<li><a href="." title="'.$directoryuppercasewords.'">Back</a></br></li>');
foreach($t as $key => $value){
$phpkill=str_replace('.php', '', $value);
$htmlkill=str_replace('.html', '', $phpkill);
$dashkill=str_replace('-',' ',$htmlkill);
$uppercasewords=ucwords($dashkill);
print('<li><a href="' . $dir . '/' . $value . '" title="'.$uppercasewords.'>' . $uppercasewords . "</a></br></li>");
}
print('</ul>');
closedir($dh);
?>
I basically made all the variables so they could explain themselves, Regular expression is not my strong point right now, just becoming familiar with php functions is more of a priority, I hope this is usefull to someone.

Re: phdwight comments about Japanese.
As far as I can see, readdir simply sucks up the byte stream that the OS generates and shots that at the browser. At any rate, it works fine on the PHP4 server I'm using.
The key is matching the "Content-type" headers and html / xml "encoding" values to what the OS is generating.
This gets more complex if you think of a folder that can be accessed by a samba share. The Japanese files saved from a windows client will be have the file name encoded in ShiftJIS. Any files created locally on the system would be in UTF8 (on a UTF8 system). This results in a jumbled up list of UTF8 and ShiftJIS file names in the same directory. Try displaying that on the one HTML page! It gets messy.
The real issue here is that basically any random stream of bytes is a valid file name on a linux box. Good luck!

Aryel wrote a function called php4_scandir which works only if the is_dir function is called with the complete path. Otherwise the function will only work within the current working directory. So changing is_dir($file) to is_dir("$dir/$file") will work.
I believe that the test on skipDots should be negated to get the desired effect.

Took a while to figure this:
scandir and readdir functions DOES NOT currently correctly read Japanese files.
When it encounters the Japanese characters, it just displays it as whatever character (mostly ???).
Save your braincells knowing this. Hope PHP 6 will fix this.

This function is similar to scandir, but works in PHP4. It uses readdir to get directory info.
<?php
function php4_scandir($dir,$listDirectories=false, $skipDots=true) {
$dirArray = array();
if ($handle = opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if (($file != "." && $file != "..") || $skipDots == true) {
if($listDirectories == false) { if(is_dir($file)) { continue; } }
array_push($dirArray,basename($file));
}
}
closedir($handle);
}
return $dirArray;

dirlst - function to get directory and subdirectory file listing. Function outputs
an array with filenames and optionally also their mod.time and/or size.
You can choose also whether to include subdirectory names into listing
Function returns number of files listed.
$srcdir - source directory (without ending slash)
$fs - output array
$p - position of relative path, usually $p = strlen($srcdir) + 1;
set to 0 to store absolute path
$getfmt - set to 1 to include filemodtime in output
$getfsz - set to 1 to include filesize in output
$getdrs - set to 1 to include subdirectory names in output
$verbose - set to 1 to display output in runtime
Usage example.
Get directory listing (files only) and save it into a file:
$srcdir = 'C:\SomeFolder';
dirlst($srcdir, $files, strlen($srcdir) + 1, 1, 1, 0, 0);
file_put_contents($filename, join("", $files));
Get listing from file and explode contents:
$files = file($fn);
foreach($files as $line) {
list($file,$fmt,$fsz)=explode('|',$line);
...
}
<?php
function dirlst($srcdir, &$fs, $p=0, $getfmt=0, $getfsz=0, $getdrs=0, $verbose=0) {
$num = 0;
if(($files = scandir($srcdir))!==false) {
foreach($files as $file) {
if($file != '.' && $file != '..') {
$srcfile = $srcdir . '\\' . $file;
$sf = substr($srcfile,$p);
$sst = stat($srcfile);
if($getfmt) { $fmt = $sst['mtime']; $sf.='|'.$fmt; }
if($getfsz) { $fsz = $sst['size']; $sf.='|'.$fsz; }
if(is_file($srcfile)) {
$fs[] = $sf."|\n";
if($verbose) echo $sf."|\n";
}
else if(is_dir($srcfile)) {
if($getdrs) { $fs[] = $sf."|\n"; if($verbose) echo $sf."|\n"; }
$num += dirlst($srcfile, $fs, $p, $getfmt, $getfsz, $getdrs, $verbose);
}
}
}
}
return $num;
}
?>
dirsort - function to sort directory listing array. Function returns sorted array.
$fs - sortable array (got by dirlst())
$col - column to sort; if the listing contains filename, filemodtime and filesize,
then: 0 - files, 1 - mod.time, 2 - size
$dsc - set to 0 to sort ascending, 1 - to sort descending
Usage example.
Sort by size, ascending:
$fs = dirsort($fs, 2, 0);
<?php
function dirsort($fs, $col=0, $dsc=0) {
foreach($fs as $line) list($col0[],$col1[],$col2[]) = explode('|',$line);
if($col==0) {
natcasesort($col0); if($dsc) $col0=array_reverse($col0,1);
$keys = array_keys($col0);
}
if($col==1) {
if($dsc) arsort($col1); else asort($col1);
$keys = array_keys($col1);
}
if($col==2) {
if($dsc) arsort($col2); else asort($col2);
$keys = array_keys($col2);
}
foreach($keys as $k) $nfs[] = $fs[$k];
return $nfs;
}

I wrote this function to read a folder and place all the folders and sub folders it contains into an array.
<?php
// Initialise empty array, otherwise an error occurs
$folders = array();
function recursive_subfolders($folders) {
// Set path here
$path = '/path/to/folder';
// Create initial "Folders" array
if ($dir = opendir($path)) {
$j = 0;
while (($file = readdir($dir)) !== false) {
if ($file != '.' && $file != '..' && is_dir($path.$file)) {
$j++;
$folders[$j] = $path . $file;
}
}
}
closedir($dir);
// Then check each folder in that array for subfolders and add the subfolders to the "Folders" array.
$j = count($folders);
foreach ($folders as $folder) {
if ($dir = opendir($folder)) {
while (($file = readdir($dir)) !== false) {
$pathto = $folder. '/' . $file;
if ($file != '.' && $file != '..' && is_dir($pathto) && !in_array($pathto, $folders)) {
$j++;
$folders[$j] = $pathto;
$folders = recursive_subfolders($folders);
}
}
}
closedir($dir);
}
sort($folders);
return $folders;
}
$folders = recursive_subfolders($folders);
?>
$folders now contains an array with the full paths to each subfolder. E.g.:
Array
(
[0] => /path/to/folder/dir1
[1] => /path/to/folder/dir1/subdir
[2] => /path/to/folder/dir1/subdir/subsubdir
[3] => /path/to/dolfer/dir2
)
This function has only been tested on Linux.

This function is recursive version of scandir, it scans all directories inside given directory. For instance : if we give path './dir1/' as argument , function will find also /dir1/dir2/file etc. - everything what`s inside given directory.

{
if (!is_dir($path)) return 0;
$list=array();
$directory = @opendir("$path"); // @-no error display
while ($file= @readdir($directory))
{
if (($file<>".")&&($file<>".."))
{
$f=$path."/".$file;
$f=preg_replace('/(\/){2,}/','/',$f); //replace double slashes

I would like to share a couple of functions I've made to get an Array of files of a certain extension inside a Directory.
<?php
// Firstly, a PHP 5 emulation
function php4_scandir($dir, $sort = 0)
{
if (PHP_VERSION >= '5') return scandir($dir, $sort);
$dirmap = array();
if(!is_dir($dir))
{
trigger_error("lib::scandir($dir): failed to open dir: Invalid argument", E_USER_WARNING);
return false;
}
$dir = opendir($dir);
while (false !== ($file = readdir($dir)))
$dirmap[] = $file;
closedir($dir);
($sort == 1) ? rsort($dirmap) : sort($dirmap);
return $dirmap;
}
/*
Then, this one converts directory files into array items.
It also can filter by file extension.
*/
function dir2arr($dir, $ext = null)
{
$arr = array();
if(PHP_VERSION >= '4.3.0')
{
# PHP 4.3.0 code
if ($dir = glob("$dir*".(!$ext ? '.*' : '{'.$ext.', '.strtoupper($ext).'}'), GLOB_NOSORT + GLOB_BRACE))
foreach ($dir as $file)
$arr[] = preg_replace("#(?:.+\/{1})*([^\.]+)\.(.+)#i", '$1', $file);
}
else
{
# PHP 4.2.x code
$dir = php4_scandir($dir); // See code snippet above
if(!$ext) $ext = '\.[a-z]+';
$pattern = "#([^\.|\.\.$]+)$ext#i";
foreach ($dir as $file)
if (preg_match($pattern, $file, $filename))
$arr[] = $filename[1];
}
return (empty($arr) ? false : $arr);
}
?>

I made a function that scans the directory and all it subfolders. You can also sort them with folders first and files after, in alphabetic order. It works with both PHP 4 and 5.
<?php
function rec_scandir($dir)
{
$files = array();
if ( $handle = opendir($dir) ) {
while ( ($file = readdir($handle)) !== false ) {
if ( $file != ".." && $file != "." ) {
if ( is_dir($dir . "/" . $file) ) {
$files[$file] = rec_scandir($dir . "/" . $file);
}else {
$files[] = $file;
}
}
}
closedir($handle);
return $files;
}
}
function cmp($a, $b)
{
if ( is_string($a) && is_string($b) ) {
return strcmp($a, $b) > 0 ? 1 : -1;
}elseif ( is_int($a) && is_int($b) ) {
return $a > $b ? 1 : -1;
}elseif ( is_int($a) && is_string($b) ) {
return 1;
}elseif ( is_string($a) && is_int($b) ) {
return -1;
}else {
return 0;
}
}
function array_ukmultisort(&$arr, $func) {
uksort($arr, $func);
while ( list($key, $val) = each($arr) ) {
if ( is_array($val) ) {
array_ukmultisort($arr[$key], $func);
}
}
}
$dir = rec_scandir(".");
array_ukmultisort($dir, "cmp");
echo "<pre>";
print_r($dir);
echo "</pre>";
?>

For non php5-users here you are this function...
It isn't set the wrapper, but I think it's enough :P.
If no pararameter is set, the scandir() function will scan the local file directory.
Set the optional parameter "$sort" to 1 to reverse the alphabetical-sorting.
<?
function scandir($dir = './', $sort = 0)
{
$dir_open = @ opendir($dir);
if (! $dir_open)
return false;
while (($dir_content = readdir($dir_open)) !== false)
$files[] = $dir_content;
if ($sort == 1)
rsort($files, SORT_STRING);
else
sort($files, SORT_STRING);
return $files;
}
?>

I made this to represent a directory tree in an array that uses the file or directory names as keys and full paths as the value for files. Directories are nested arrays.
<?php
function generatePathTree($rootPath) {
$pathStack = array($rootPath);
$contentsRoot = array();
$contents = &$contentsRoot;
while ($path = array_pop($pathStack)) {
$contents[basename($path)] = array();
$contents = &$contents[basename($path)];
foreach (scandir($path) as $filename) {
if ('.' != substr($filename, 0, 1)) {
$newPath = $path.'/'.$filename;
if (is_dir($newPath)) {
array_push($pathStack, $newPath);
$contents[basename($newPath)] = array();
} else {
$contents[basename($filename)] = $newPath;
}
}
}
}
return $contentsRoot[basename($rootPath)];
}
?>
The function will return something like this:
Array
(
[index.php] => /usr/local/www/index.php
[js] => Array
(
[async.js] => /usr/local/www/js/async.js
[dom.js] => /usr/local/www/js/dom.js
[effects.js] => /usr/local/www/js/effects.js
[prototype.js] => /usr/local/www/js/prototype.js
)
[logo.png] => /usr/local/www/logo.png
[server.php] => /usr/local/www/server.php
[test.js] => /usr/local/www/test.js
)

For directory containing files like (for example) -.jpg the results of scandir are a little "weird" ;)
<?php
$dir = '/somedir';
$files = scandir($dir);
print_r($files);
?>
Array
(
[0] => -.jpg
[1] => .
[2] => ..
[3] => foo.txt
[4] => somedir
)
Beware - sorting is in ASCII order :)

using sort of scandir() that returns the content sorted by Filemodificationtime.
<?php
function scandir_by_mtime($folder) {
$dircontent = scandir($folder);
$arr = array();
foreach($dircontent as
