Easy way to get rid of the dots that scandir() picks up in Linux environments:
<?php
$directory = '/path/to/my/directory';
$scanned_directory = array_diff(scandir($directory), array('..', '.'));
?>
scandir
(PHP 5, PHP 7, PHP 8)
scandir — List files and directories inside the specified path
Descrizione
scandir(string
$directory, int $sorting_order = SCANDIR_SORT_ASCENDING, ?resource $context = null): array|false
Returns an array of files and directories from the
directory.
Elenco dei parametri
-
directory -
The directory that will be scanned.
-
sorting_order -
By default, the sorted order is alphabetical in ascending order. If the optional
sorting_orderis set toSCANDIR_SORT_DESCENDING, then the sort order is alphabetical in descending order. If it is set toSCANDIR_SORT_NONEthen the result is unsorted. -
context -
For a description of the
contextparameter, refer to the streams section of the manual.
Valori restituiti
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.

Example #1 A simple scandir() example
<?php
$dir = '/tmp';
$files1 = scandir($dir);
$files2 = scandir($dir, SCANDIR_SORT_DESCENDING);
print_r($files1);
print_r($files2);
?>Il precedente esempio visualizzerà qualcosa simile a:
Array
(
[0] => .
[1] => ..
[2] => bar.php
[3] => foo.txt
[4] => somedir
)

Here is my 2 cents. I wanted to create an array of my directory structure recursively. I wanted to easely access data in a certain directory using foreach. I came up with the following:
<?php
function dirToArray($dir) {
$result = array();
$cdir = scandir($dir);
foreach ($cdir as $key => $value)
{
if (!in_array($value,array(".","..")))
{
if (is_dir($dir . DIRECTORY_SEPARATOR . $value))
{
$result[$value] = dirToArray($dir . DIRECTORY_SEPARATOR . $value);
}
else
{
$result[] = $value;
}
}
}
return $result;
}
?>
Output
Array
(
[subdir1] => Array
(
[0] => file1.txt
[subsubdir] => Array
(
[0] => file2.txt
[1] => file3.txt
)
)
[subdir2] => Array
(
[0] => file4.txt
}
)

Someone wrote that array_slice could be used to quickly remove directory entries "." and "..". However, "-" is a valid entry that would come before those, so array_slice would remove the wrong entries.

I needed to find a way to get the full path of all files in the directory and all subdirectories of a directory.
Here's my solution: Recursive functions!
<?php
function find_all_files($dir)
{
$root = scandir($dir);
foreach($root as $value)
{
if($value === '.' || $value === '..') {continue;}
if(is_file("$dir/$value")) {$result[]="$dir/$value";continue;}
foreach(find_all_files("$dir/$value") as $value)
{
$result[]=$value;
}
}
return $result;
}

Needed something that could return the contents of single or multiple directories, recursively or non-recursively,
for all files or specified file extensions that would be
accessible easily from any scope or script.
And I wanted to allow overloading cause sometimes I'm too lazy to pass all params.
<?php
class scanDir {
static private $directories, $files, $ext_filter, $recursive;
// ----------------------------------------------------------------------------------------------
// scan(dirpath::string|array, extensions::string|array, recursive::true|false)
static public function scan(){
// Initialize defaults
self::$recursive = false;
self::$directories = array();
self::$files = array();
self::$ext_filter = false;
// Check we have minimum parameters
if(!$args = func_get_args()){
die("Must provide a path string or array of path strings");
}
if(gettype($args[0]) != "string" && gettype($args[0]) != "array"){
die("Must provide a path string or array of path strings");
}
// Check if recursive scan | default action: no sub-directories
if(isset($args[2]) && $args[2] == true){self::$recursive = true;}
// Was a filter on file extensions included? | default action: return all file types
if(isset($args[1])){
if(gettype($args[1]) == "array"){self::$ext_filter = array_map('strtolower', $args[1]);}
else
if(gettype($args[1]) == "string"){self::$ext_filter[] = strtolower($args[1]);}
}
// Grab path(s)
self::verifyPaths($args[0]);
return self::$files;
}
static private function verifyPaths($paths){
$path_errors = array();
if(gettype($paths) == "string"){$paths = array($paths);}
foreach($paths as $path){
if(is_dir($path)){
self::$directories[] = $path;
$dirContents = self::find_contents($path);
} else {
$path_errors[] = $path;
}
}
if($path_errors){echo "The following directories do not exists<br />";die(var_dump($path_errors));}
}
// This is how we scan directories
static private function find_contents($dir){
$result = array();
$root = scandir($dir);
foreach($root as $value){
if($value === '.' || $value === '..') {continue;}
if(is_file($dir.DIRECTORY_SEPARATOR.$value)){
if(!self::$ext_filter || in_array(strtolower(pathinfo($dir.DIRECTORY_SEPARATOR.$value, PATHINFO_EXTENSION)), self::$ext_filter)){
self::$files[] = $result[] = $dir.DIRECTORY_SEPARATOR.$value;
}
continue;
}
if(self::$recursive){
foreach(self::find_contents($dir.DIRECTORY_SEPARATOR.$value) as $value) {
self::$files[] = $result[] = $value;
}
}
}
// Return required for recursive search
return $result;
}
}
?>
Usage:
scanDir::scan(path(s):string|array, [file_extensions:string|array], [subfolders?:true|false]);
<?php
//Scan a single directory for all files, no sub-directories
$files = scanDir::scan('D:\Websites\temp');
//Scan multiple directories for all files, no sub-dirs
$dirs = array(
'D:\folder';
'D:\folder2';
'C:\Other';
);
$files = scanDir::scan($dirs);
// Scan multiple directories for files with provided file extension,
// no sub-dirs
$files = scanDir::scan($dirs, "jpg");
//or with an array of extensions
$file_ext = array(
"jpg",
"bmp",
"png"
);
$files = scanDir::scan($dirs, $file_ext);
// Scan multiple directories for files with any extension,
// include files in recursive sub-folders
$files = scanDir::scan($dirs, false, true);
// Multiple dirs, with specified extensions, include sub-dir files
$files = scanDir::scan($dirs, $file_ext, true);

A simple recursive function to list all files and subdirectories in a directory:
<?php
function listAllFiles($dir) {
$array = array_diff(scandir($dir), array('.', '..'));
foreach ($array as &$item) {
$item = $dir . $item;
}
unset($item);
foreach ($array as $item) {
if (is_dir($item)) {
$array = array_merge($array, listAllFiles($item . DIRECTORY_SEPARATOR));
}
}
return $array;
}

scandir() with regexp matching on file name and sorting options based on stat().
<?php
function myscandir($dir, $exp, $how='name', $desc=0)
{
$r = array();
$dh = @opendir($dir);
if ($dh) {
while (($fname = readdir($dh)) !== false) {
if (preg_match($exp, $fname)) {
$stat = stat("$dir/$fname");
$r[$fname] = ($how == 'name')? $fname: $stat[$how];
}
}
closedir($dh);
if ($desc) {
arsort($r);
}
else {
asort($r);
}
}
return(array_keys($r));
}
$r = myscandir('./book/', '/^article[0-9]{4}\.txt$/i', 'ctime', 1);
print_r($r);
?>
files can be sorted on name and stat() attributes, ascending and descending:
name file name
dev device number
ino inode number
mode inode protection mode
nlink number of links
uid userid of owner
gid groupid of owner
rdev device type, if inode device *
size size in bytes
atime time of last access (Unix timestamp)
mtime time of last modification (Unix timestamp)
ctime time of last inode change (Unix timestamp)
blksize blocksize of filesystem IO *
blocks number of blocks allocated

Scandir on steroids:
For when you want to filter your file list, or only want to list so many levels of subdirectories...
<?php
function dirList($path="", $types=2, $levels=1, $aFilter=array()) {
// returns an array of the specified files/directories
// start search in $path (defaults to current working directory)
// return $types: 2 => files; 1 => directories; 3 => both;
// $levels: 1 => look in the $path only; 2 => $path and all children;
// 3 => $path, children, grandchildren; 0 => $path and all subdirectories;
// less than 0 => complement of -$levels, OR everything starting -$levels down
// e.g. -1 => everthing except $path; -2 => all descendants except $path + children
// Remaining argument(s) is(are) a filter array(list) of regular expressions which operate on the full path.
// First character (before the '/' of the regExp) '-' => NOT.
// First character (after a possible '-') 'd' => apply to directory name
// The filters may be passed in as an array of strings or as a list of strings
// Note that output directories are prefixed with a '*' (done in the line above the return)
$dS = DIRECTORY_SEPARATOR;
if (!($path = realpath($path?$path:getcwd()))) return array(); // bad path
// next line rids terminating \ on drives (works since c: == c:\ on PHP). OK in *nix?
if (substr($path,-1)==$dS) $path = substr($path,0,-1);
if (is_null($types)) $types = 2;
if (is_null($levels)) $levels = 1;
if (is_null($aFilter)) $aFilter=array();
// last argument may be passed as a list or as an array
$aFilter = array_slice(func_get_args(),3);
if ($aFilter && gettype($aFilter[0])=="array") $aFilter=$aFilter[0];
$adFilter = array();
// now move directory filters to separate array:
foreach ($aFilter as $i=>$filter) // for each directory filter...
if (($pos=stripos(" $filter","d")) && $pos<3) { // next line eliminates the 'd'
$adFilter[] = substr($filter,0,$pos-1) . substr($filter,$pos);
unset($aFilter[$i]); }
$aFilter = array_merge($aFilter); // reset indeces
$aRes = array(); // results, $aAcc is an Accumulator
$aDir = array($path); // dirs to check
for ($i=$levels>0?$levels++:-1;($aAcc=array())||$i--&&$aDir;$aDir=$aAcc)
while ($dir = array_shift($aDir))
foreach (scandir ($dir) as $fileOrDir)
if ($fileOrDir!="." && $fileOrDir!="..") {
if ($dirP = is_dir ($rp="$dir$dS$fileOrDir"))
if (pathFilter("$rp$dS", $adFilter))
$aAcc[] = $rp;
if ($i<$levels-1 && ($types & (2-$dirP)))
if (pathFilter($rp, $aFilter))
$aRes[] = ($dirP?"*":"") . $rp; }
return $aRes;
}
?>
example usage:
<?php
define ("_", NULL);
// this will find all non .jpg, non .Thumbs.db files under c:\Photo
$aFiles = dirList('c:\Photo', _, 0, '-/\.jpg$/i', '-/\\\\Thumbs.db$/');
$aFiles = dirList(); // find the files in the current directory
// next lines will find .jpg files in non Photo(s) subdirectories, excluding Temporary Internet Files
set_time_limit(60); // iterating from the top level can take a while
$aFiles = dirList("c:\\", _, 0, '/\.jpg$/i', '-d/\\\\Photos?$/i', '-d/Temporary Internet/i');
?>
Note that this function will consume a lot of time if scanning large
directory structures (which is the reason for the '[-]d/.../' filters).

If you use array_diff() to eliminate "." and ".." you must use array_values() on the result because array_diff() will return an associative array, which may cause problems for a for loop beginning at 0.
$files = array_values(array_diff(scandir($directory), array('..', '.')));

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 :)

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"));
---
Array
(
[0] => www/index.php
[1] => www/admin.php
[3] => www/css/css.css
[4] => www/articles/2007/article1.txt
[4] => www/articles/2006/article1.txt
[8] => www/img/img1.png
)

Unless you specify no sorting, file names are sorted in ASCII alphabetic order, meaning numbers first, then uppercase, then lowercase letters, even on operating systems whose file system ignores the case of file names when it does its own sorting.
For example, on Mac OS, the following files will appear in this order in the Finder, when your disk is formated using the standard file system:
1file.php
a.inc
B.txt
c.txt
However, scandir will produce an array in the following order:
1file.php
B.txt
a.inc
c.txt

Hello all,
I just added a extension filter to the getDirectoryTree function, so it can filter an extension for files in the folders/subfolders:
<?php
function getDirectoryTree( $outerDir , $x){
$dirs = array_diff( scandir( $outerDir ), Array( ".", ".." ) );
$dir_array = Array();
foreach( $dirs as $d ){
if( is_dir($outerDir."/".$d) ){
$dir_array[ $d ] = getDirectoryTree( $outerDir."/".$d , $x);
}else{
if (($x)?ereg($x.'$',$d):1)
$dir_array[ $d ] = $d;
}
}
return $dir_array;
}
$dirlist = getDirectoryTree('filmes','flv');
?>

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
)

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
?>

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.

If you have a folder with many files and/or subfolders, doing a recursive scandir will likely either slow down your application, or cause a high rise in RAM consumption due to the large size of the generated array.
To help with this, as well as to make processing of files in a folder easier, I wrote a function that reads a folder and its subfolders recursively, and calls a function upon each match.
<?php
/**
* Calls a function for every file in a folder.
*
* @author Vasil Rangelov a.k.a. boen_robot
*
* @param string $callback The function to call. It must accept one argument that is a relative filepath of the file.
* @param string $dir The directory to traverse.
* @param array $types The file types to call the function for. Leave as NULL to match all types.
* @param bool $recursive Whether to list subfolders as well.
* @param string $baseDir String to append at the beginning of every filepath that the callback will receive.
*/
function dir_walk($callback, $dir, $types = null, $recursive = false, $baseDir = '') {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
if ($file === '.' || $file === '..') {
continue;
}
if (is_file($dir . $file)) {
if (is_array($types)) {
if (!in_array(strtolower(pathinfo($dir . $file, PATHINFO_EXTENSION)), $types, true)) {
continue;
}
}
$callback($baseDir . $file);
}elseif($recursive && is_dir($dir . $file)) {
dir_walk($callback, $dir . $file . DIRECTORY_SEPARATOR, $types, $recursive, $baseDir . $file . DIRECTORY_SEPARATOR);
}
}
closedir($dh);
}
}
?>
Of course, because it is recursive, a folder with many levels of folders could potentially consume lots of memory, but then again, so can every other recursive scandir implementation here.
BTW, there's also the RecursiveDirectoryIterator SPL class:
http://bg.php.net/manual/en/class.recursivedirectoryiterator.php
which, even if using the same approach, will most likely be faster and hold down deeper levels (because it works on the C level), but this one will always work, regardless of settings... even on PHP4.
Point is, avoid recursive scandir implementations.

easy way to list every item in a directory
<?php
$itemnum = 1;
$dir = 'C:/Path/To/Directory';
foreach(scandir($dir) as $item){
if (!($item == '.')) {
if (!($item == '..')) {
echo($itemnum." = ".$item."<br>");
$itemnum = ($itemnum + 1);
}}}

Was looking for a simple way to search for a file/directory using a mask. Here is such a function.
By default, this function will keep in memory the scandir() result, to avoid scaning multiple time for the same directory.
Requires at least PHP5.
<?php
function sdir( $path='.', $mask='*', $nocache=0 ){
static $dir = array(); // cache result in memory
if ( !isset($dir[$path]) || $nocache) {
$dir[$path] = scandir($path);
}
foreach ($dir[$path] as $i=>$entry) {
if ($entry!='.' && $entry!='..' && fnmatch($mask, $entry) ) {
$sdir[] = $entry;
}
}
return ($sdir);
}
?>

This is a modification of scanDirectories function that generates a list of all files in the chosen directory and all subdirectories of specific extentions $allowext
<?php
function scanDirectories($rootDir, $allowext, $allData=array()) {
$dirContent = scandir($rootDir);
foreach($dirContent as $key => $content) {
$path = $rootDir.'/'.$content;
$ext = substr($content, strrpos($content, '.') + 1);
if(in_array($ext, $allowext)) {
if(is_file($path) && is_readable($path)) {
$allData[] = $path;
}elseif(is_dir($path) && is_readable($path)) {
// recursive callback to open new directory
$allData = scanDirectories($path, $allData);
}
}
}
return $allData;
}
$rootDir = "www";
$allowext = array("zip","rar","html");
$files_array = scanDirectories($rootDir,$allowext);
print_r($files_array);
?>

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

A nice way to filter the files/directories you get back from scandir:
<?php
function pathFilter ($path, $aFilter) {
// returns true iff $path survives the tests from $aFilter
// $aFilter is an array of regular expressions: [-]/regExp/modifiers
// if there is a leading '-' it means exclude $path upon a match (a NOT test)
// If the first expression has a leading '-', $path is in, unless it gets excluded.
// Otherwise, $path is out, unless it gets included via the filter tests.
// The tests are applied in succession.
// A NOT test is applied only if $path is currently (within the tests) included
// Other tests are applied only if $path is currently excluded. Thus,
// array("/a/", "-/b/", "/c/") => passes if $path has a c or if $path has an a but no b
// array("/a/", "/c/", "-/b/") => passes if $path has an a or c, but no b
// array("-/b/", "/a/", "/c/") => passes if $path has no b, or if $path has an a or c
if (!$aFilter) return true; // automatic inclusion (pass) if no filters
foreach ($aFilter as $filter) break; // we don't know how it's indexed
$in = $filter[0]=="-"; // initial in/exclusion based on first filter
foreach ($aFilter as $filter) // walk the filters
if ($in==$not=($filter[0]=="-")) // testing only when necessary
$in ^= preg_match(substr($filter,$not),$path); // flip in/exclusion upon a match
return $in;
}

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 $filename) {
if ($filename != '.' && $filename != '..') {
if (filemtime($folder.$filename) === false) return false;
$dat = date("YmdHis", filemtime($folder.$filename));
$arr[$dat] = $filename;
}
}
if (!ksort($arr)) return false;
return $arr;
}
?>
returns false if an error occured
otherwise it returns an array like this.
