A function I created to non-recursively get the path of all files and folders including sub-directories of a given folder.
Though I have not tested it completely, it seems to be working.
<?php
/**
* Finds path, relative to the given root folder, of all files and directories in the given directory and its sub-directories non recursively.
* Will return an array of the form
* array(
* 'files' => [],
* 'dirs' => [],
* )
* @author sreekumar
* @param string $root
* @result array
*/
function read_all_files($root = '.'){
$files = array('files'=>array(), 'dirs'=>array());
$directories = array();
$last_letter = $root[strlen($root)-1];
$root = ($last_letter == '\\' || $last_letter == '/') ? $root : $root.DIRECTORY_SEPARATOR;
$directories[] = $root;
while (sizeof($directories)) {
$dir = array_pop($directories);
if ($handle = opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if ($file == '.' || $file == '..') {
continue;
}
$file = $dir.$file;
if (is_dir($file)) {
$directory_path = $file.DIRECTORY_SEPARATOR;
array_push($directories, $directory_path);
$files['dirs'][] = $directory_path;
} elseif (is_file($file)) {
$files['files'][] = $file;
}
}
closedir($handle);
}
}
return $files;
}
?>
readdir
(PHP 4, PHP 5, PHP 7, PHP 8)
readdir — Legge una voce dall'handle della directory
Descrizione
Restituisce il nomefile del file successivo della directory. I nomi dei file vengono restituiti secondo l'ordine in cui sono memorizzati nel filesystem.
Si faccia caso al modo in cui il valore restituito da readdir()
viene controllato negli esempi successivi. Viene controllato esplicitamente
che il valore restituito sia identico a (uguale a e dello
stesso tipo di (vedere Comparison
Operators per maggiori informazioni) false altrimenti avverrebbe che
ogni nome di directory il cui nome fosse valutato false interromperebbe il
loop (per esempio una directory chiamata "0").
Example #1 Elenca tutti i file presenti in una directory
<?php
// Nota che l'operatore !== non è esistito fino alla versione 4.0.0-RC2
if ($handle = opendir('/percorso/ai/file')) {
echo "Handle della directory: $handle\n";
echo "File:\n";
/* Questa è la maniera corretta di eseguire un loop all'interno di una directory. */
while (false !== ($file = readdir($handle))) {
echo "$file\n";
}
/* Questa è la maniera SCORRETTA di eseguire un loop all'interno di una directory. */
while ($file = readdir($handle)) {
echo "$file\n";
}
closedir($handle);
}

Nota che readdir() restituirà le voci .

eliminare:
Example #2
Elenca tutti i file della directory in uso ed elimina .

<?php
if ($handle = opendir('.')) {

if ($file != "." && $file != "..") {

PHP includes and alternative boolean operators whose precedence is below assignment. This means that an expression of the form
<?php
if(($a = something()) && $a !== false) … ;
?>
can be written as
<?php
if($a = something() and $a !== false) … ;
?>
In this case, the loop can be written as:
<?php
while ($entry = readdir($handle) and $entry !== false) {
// etc
}
?>

Here is an updated version of preg_find() [which has been linked from the glob() man page for years] - this function should provide most of what you want back from reading files, directories, different sorting methods, recursion, and perhaps most powerful of all the ability to pattern match with a PCRE regex.
You can get preg_find here: http://www.pgregg.com/projects/php/preg_find/preg_find.php.txt
or if you prefer colourful .phps format: http://www.pgregg.com/projects/php/preg_find/preg_find.phps
or scoll down to the end of this note.
I wrote several examples on how to use it on my blog at: http://www.pgregg.com/forums/viewtopic.php?tid=73
simple glob() type replacement:
$files = preg_find('/./', $dir);
recursive?
$files = preg_find('/./', $dir, PREG_FIND_RECURSIVE);
pattern match? find all .php files:
$files = preg_find('/\.php$/D', $dir, PREG_FIND_RECURSIVE);
sorted alphabetically?
$files = preg_find('/\.php$/D', $dir, PREG_FIND_RECURSIVE|PREG_FIND_SORTKEYS);
sorted in by filesize, in descending order?
$files = preg_find('/./', $dir,
PREG_FIND_RECURSIVE|PREG_FIND_RETURNASSOC |PREG_FIND_SORTFILESIZE|PREG_FIND_SORTDESC);
$files=array_keys($files);
sorted by date modified?
$files = preg_find('/./', $dir,
PREG_FIND_RECURSIVE|PREG_FIND_RETURNASSOC |PREG_FIND_SORTMODIFIED);
$files=array_keys($files);

A variation on listing all the files in a directory recursively. The code illustrates a basic technique : the use of an auxiliary function. It avoids building temporary lists which are merged on the way back. Note that the array which collects the information must be passed by reference.
<?php
function listdir($dir='.') {
if (!is_dir($dir)) {
return false;
}
$files = array();
listdiraux($dir, $files);
return $files;
}
function listdiraux($dir, &$files) {
$handle = opendir($dir);
while (($file = readdir($handle)) !== false) {
if ($file == '.' || $file == '..') {
continue;
}
$filepath = $dir == '.' ? $file : $dir . '/' . $file;
if (is_link($filepath))
continue;
if (is_file($filepath))
$files[] = $filepath;
else if (is_dir($filepath))
listdiraux($filepath, $files);
}
closedir($handle);
}
$files = listdir('.');
sort($files, SORT_LOCALE_STRING);
foreach ($files as $f) {
echo $f, "\n";
}
?>

Looking through the examples, I can't see any that do a simple check on the value of the directory resource that opendir returns and is subsequently used by readdir.
If opendir returns false, and you simply pass this to the readdir call in the while loop, you will get an infinite loop.
A simple test helps prevent this:
<?php
$dir = opendir($path);
while ($dir && ($file = readdir($dir)) !== false) {
// do stuff
}
?>

Warning when using readdir() on certain versions of CentOS on NFS-mounted directories:
This is not a bug with PHP's readdir, but a bug with certain versions of CentOS's readdir implementation. According to Post #6213 in the CentOS Bugs forum, when using CentOS kernel versions 2.6.18-348 through 2.6.18-348.3.1, invoking readdir on an NFS-mounted directory may not return all the entries. Since PHP's readdir() uses this library, the issue is manifest in PHP as well.
According to the post, upgrading to version 2.6.18-348.4.1.el5 should solve the issue, though I haven't tried it.
glob() does NOT seem to suffer from this same vulnerability.

Regarding the warning:
This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE.
Of course, this means that if you use:
<?php
if($entry = readdir($handle) == false) …
?>
or
<?php
while($entry = readdir($handle)) …
?>
you may get a false false, as it were.
As far as I can tell, the only time this would actually occur is if you encounter an entry of 0.
According to
https://www.php.net/manual/en/language.types.boolean.php#language.types.boolean.casting
this appears to be the only string which will evaluate to false.

Handy little function that returns the number of files (not directories) that exists under a directory.
Choose if you want the function to recurse through sub-directories with the second parameter -
the default mode (false) is just to count the files directly under the supplied path.
<?php
/**
* Return the number of files that resides under a directory.
*
* @return integer
* @param string (required) The directory you want to start in
* @param boolean (optional) Recursive counting. Default to FALSE.
* @param integer (optional) Initial value of file count
*/
function num_files($dir, $recursive=false, $counter=0) {
static $counter;
if(is_dir($dir)) {
if($dh = opendir($dir)) {
while(($file = readdir($dh)) !== false) {
if($file != "." && $file != "..") {
$counter = (is_dir($dir."/".$file)) ? num_files($dir."/".$file, $recursive, $counter) : $counter+1;
}
}
closedir($dh);
}
}
return $counter;
}
// Usage:
$nfiles = num_files("/home/kchr", true); // count all files that resides under /home/kchr, including subdirs
$nfiles = num_files("/tmp"); // count the files directly under /tmp

It should work, but it'll be better to read section 13.1.3 Cache-control Mechanisms of RFC 2616 available at http://rfc.net/rfc2616.html before you start with confusing proxies on the way from you and the client.
Reading it is the best way to learn how proxies work, what should you do to modify cache-related headers of your documents and what you should never do again. :-)
And of course not reading RFCs is the best way to never learn how internet works and the best way to behave like Microsoft corp.
Have a nice day!

This function is used to display random image i.e. at header position of a site. It reads the whole directory and then randomly print the image. I think it may be useful for someone.
<?php
if ($handle = opendir('images/')) {
$dir_array = array();
while (false !== ($file = readdir($handle))) {
if($file!="." && $file!=".."){
$dir_array[] = $file;

Here's a handy function you can use to list the files in the directory you specify, their type (dir or file) and whether they are hidden.
You could modify it to do other things too.
<?php
function listDirs($where){
echo "<table border=\"1\"><tr><td><b>Name</b></td><td><b>Type</b></td>";
echo "<td><b>Invisible (Hidden)?</b></td></tr>";
$itemHandler=opendir($where);
$i=0;
while(($item=readdir($itemHandler)) !== false){
if(substr($item, 0, 1)!="."){
if(is_dir($item)){
echo "<tr><td>$item</td><td>Directory</td><td>No</td></tr>";
}else{
echo "<tr><td>$item</td><td>File</td><td>No</td></tr>";
}
$i++;
}else{
if(is_dir($item)){
echo "<tr><td>$item</td><td>Directory</td><td>Yes</td></tr>";
}else{
echo "<tr><td>$item</td><td>File</td><td>Yes</td></tr>";
}
$i++;
}
}
echo "</table>";
}
?>
Then call it like this.
<?php
listDirs(DIR);
?>
Example:
<?php
listDirs("/tests/directorylisting");
?>
You get a table like this.
Name Type Invisible (Hidden)?
. Directory Yes
.. Directory Yes
.DS_Store File Yes
.localized File Yes
index.php File No
OOOLS Directory No
QwerpWiki.php File No

A very flexible function to recursively list all files in a directory with the option to perform a custom set of actions on those files and/or include extra information about them in the returned data.
----------
SYNTAX:
$array = process_dir ( $dir , $recursive = FALSE )
$dir (STRING) = Directory to process
$recursive (BOOLEAN) = [Optional] Recursive if set to TRUE
RETURN VALUES:
The function returns an indexed array, one entry for every file. Each entry is an associative array, containing the basic information 'filename' (name of file) and 'dirpath' (directory component of path to file), and any additional keys you configure. Returns FALSE on failure.
----------
To allow you to configure another key, the entry for each file is stored in an array, "$entry" for each iteration. You can easily return any additional data for a given file using $entry['keyname'] = ... (Note that this data can be any variable type - string, bool, float, resource etc)
There is a string variable "$path" available, which contains the full path of the current file, relative to the initial "$dir" supplied at function call. This data is also available in it's constituent parts, "$dir" and "$file". Actions for each file can be constructed on the basis of these variables. The variables "$list", "$handle" and "$recursive" should not be used within your code.
----------
Simply insert you code into the sections indicated by the comments below and your away!
The following example returns filename, filepath, and file modified time (in a human-readable string) for all items, filesize for all files but not directories, and a resource stream for all files with 'log' in the filename (but not *.log files).
<?php
function process_dir($dir,$recursive = FALSE) {
if (is_dir($dir)) {
for ($list = array(),$handle = opendir($dir); (FALSE !== ($file = readdir($handle)));) {
if (($file != '.' && $file != '..') && (file_exists($path = $dir.'/'.$file))) {
if (is_dir($path) && ($recursive)) {
$list = array_merge($list, process_dir($path, TRUE));
} else {
$entry = array('filename' => $file, 'dirpath' => $dir);
//---------------------------------------------------------//
// - SECTION 1 - //
// Actions to be performed on ALL ITEMS //
//----------------- Begin Editable ------------------//
$entry['modtime'] = filemtime($path);
//----------------- End Editable ------------------//
do if (!is_dir($path)) {
//---------------------------------------------------------//
// - SECTION 2 - //
// Actions to be performed on FILES ONLY //
//----------------- Begin Editable ------------------//
$entry['size'] = filesize($path);
if (strstr(pathinfo($path,PATHINFO_BASENAME),'log')) {
if (!$entry['handle'] = fopen($path,r)) $entry['handle'] = "FAIL";
}
//----------------- End Editable ------------------//
break;
} else {
//---------------------------------------------------------//
// - SECTION 3 - //
// Actions to be performed on DIRECTORIES ONLY //
//----------------- Begin Editable ------------------//
//----------------- End Editable ------------------//
break;
} while (FALSE);
$list[] = $entry;
}
}
}
closedir($handle);
return $list;
} else return FALSE;
}
$result = process_dir('C:/webserver/Apache2/httpdocs/processdir',TRUE);
// Output each opened file and then close
foreach ($result as $file) {
if (is_resource($file['handle'])) {
echo "\n\nFILE (" . $file['dirpath'].'/'.$file['filename'] . "):\n\n" . fread($file['handle'], filesize($file['dirpath'].'/'.$file['filename']));
fclose($file['handle']);
}
}

Find a file or folder within a directory. Say we want will loop n times by all subdirectories of a root directory and find a particular folder or file and know your address.
In my case I needed to find each existing file in a directory metadata.opf a Calibre library and take all the data for each document this, if we consider that this directory had 20,000 folders author is a task that is humanly impossible . This recursive algorithm achieves do my homework. I hope it will help you.
<?php
$root = '../Classes';
$search_parameter = "CachedObjectStorageFactory.php";
//if we call the function spider as spider($root);
//will show all the directory content including subdirectories
//if we call the function spider as spider('../Classes', 'Shared');
//and will show the address of the directory
spider($root, $search_parameter);
closedir();
function spider($dir,$fileName=""){
$handle = opendir($dir);
while($file= readdir($handle)){
if($file != "." && $file != ".."){
if($fileName=="")
echo $dir."/".$file."<br>";

this function recurrsively goes to a particular depth and stops after the depth is reached.
function read_path($root = '.', $depth = 1) {
if($depth == 0) {
return;
}
$last_letter = $root[strlen($root)-1];
$root = ($last_letter == '\\' || $last_letter == '/') ? $root : $root.DIRECTORY_SEPARATOR;
$files = array('files'=>array(), 'dirs'=>array());
if ($handle = opendir($root)) {
while (false !== ($file = readdir($handle))) {
if ($file == '.' || $file == '..') {
continue;
}
$file = $root.$file;
if (is_dir($file)) {
$directory_path = $file.DIRECTORY_SEPARATOR;
$files['dirs'][$directory_path] = NULL;
} elseif (is_file($file)) {
$files['files'][] = $file;
}
}
closedir($handle);
}
$done = [$root=>$files];
foreach ($done[$root]['dirs'] as $key=>$value) {
$done[$root]['dirs'][$key] = $this->read_path($key, $depth-1);
}
return $done[$root];
}

Yet another view files by extension

<?php

Please be aware that readdir() and opendir() etc will return sorted directory listings automatically on some operating systems, whilst others it will not.
On later versions of windows, you can usually be guaranteed alphabetically sorted file listings from readdir(), and on Linux there is no such guarantee. If you require any particular sort order you should read the results to an array and use asort() or rsort() on it, or similar, to get the results into the order you need.
