Another way to sort files from directories.
<?php
$path = getcwd();
$dh = opendir($path);
print "Directories <br>************************* <br>";
while (($dir = readdir($dh)) !== false) {
if ( $dir != "." && $dir != ".." ){
$file = @fopen("$path/$dir", "r");
if (!$file){
print "<a href='$dir'>$dir</a><br>";
}
}
}
closedir($dh);
$path = getcwd();
$dh = opendir($path);
print "<br>Files <br>************************* <br>";
while (($dir = readdir($dh)) !== false) {
if ( $dir != "." && $dir != ".." ){
$file = @fopen("$path/$dir", "r");
if ($file){
print "<a href='$dir'>$dir</a><br>";
}
}
}
closedir($dh);
?>
readdir
范例
例子 1. 列出目录中的所有文件 请留意下面例子中检查 readdir() 返回值的风格。这里明确地测试返回值是否全等于（值和类型都相同――更多信息参见比较运算符）FALSE，否则任何目录项的名称求值为 FALSE 的都会导致循环停止（例如一个目录名为“0”）。

better version of the yesterdays script
first it reads all content and divides it into files and directorys (two arrays)
then the arrays will be sorted and an output is given (directorys first, then the files)
<?php
$startdir = "downloads/";
$dir = "$startdir$subdir";
echo "<table border=\"1\">\n";
echo "<tr>\n";
echo "<td><a href=\"directory.php\">UP ..</a></td>";
echo "<td>$subdir</td>";
echo "</tr>\n";
$array_dir = array();
$array_file = array();
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false)
{
$filename = $file;
$filetype = filetype($dir . $file);
if ($filename == ".." OR $filename == ".")
{
echo "";
}
else
{
if ($filetype == "file")
{
$array_file[] = $filename;
}
elseif ($filetype == "dir")
{
$array_dir[] = $filename;
}
}
}
closedir($dh);
}
}
sort($array_dir);
foreach ($array_dir as $item) {
$subdir_n = "$subdir$item/";
echo "<tr>\n";
echo "<td>dir</td>\n";
echo "<td><a href=\"directory.php?subdir=$subdir_n\">$item</a></td>\n";
echo "</tr>\n";
}
sort($array_file);
foreach ($array_file as $item) {
$subdir_n = "$subdir$item/";
echo "<tr>\n";
echo "<td>file</td>\n";
echo "<td>$item</td>\n";
echo "</tr>\n";
}
echo "</table>\n";

Hi, i created a simple module to sort the contents of a dir
using sort(). In the first part; it get the content of the directory (not sorted) and in the second part; it sort the contents and write line per line the result
Sorry for my poor english;!
<?
$dir = getcwd(); // the best option is getcwd()
$dh = opendir($dir);
while (false !== ($file = readdir($dh))) {
if (is_dir($file) && filesize($file)) {} else { echo "$file\n";}
}
sort($gi); // can be rsort($gi);
while ($cn < $to){
echo ("$gi[$cn]\n");
$cn = $cn +1;
}
?>

I have recently created a function I have called filearray, which makes use of opendir(), readdir(), and closedir(), to create and output a recursive array in which all files and folders underneath the target main folder ( / = default) that you can parse how you want, array_search it or whatever you need to do. Search 1 or more directories automatically recursively with this.
function filearray($start="/") {
$dir=opendir($start);
while (false !== ($found=readdir($dir))) { $getit[]=$found; }
foreach($getit as $num => $item) {
if (is_dir($start.$item) && $item!="." && $item!="..") { $output["{$item}"]=filearray($start.$item."/"); }
if (is_file($start.$item)) { $output["{$item}"]="FILE"; }
}
closedir($dir);
return $output;

With the help of a clan member from the clan I'm in, I created the following script to give you a password protected list of files that allows directory traversing. It will not allow you to view any file not in the path you chose.
<?
define("def_path", 'your path here');
define("def_pass", 'your password here');
$path = def_path;
$pass = "";
foreach ($_GET as $k => $v) {
if ("path"==$k)
$path="$v/";
if ("pass"==$k)
$pass="$v";
}
// make sure they cant get access to other files
if (strpos($path,def_path) != false)
$path=def_path;
if (strpos($path,"..")!=false)
$path=def_path;
if (!is_dir($path))
$path=def_path;
if (rtrim(substr_replace($path, ' ', 2, 1000)) != def_path) // change 2 to be what you need to get your entire path for the comparison
$path=def_path;
function read_dir($pass, $dirToRead) {
$path4 = opendir($dirToRead);
$dirs = array();
$files = array();
while (false !== ($file = readdir($path4))) {
if($file!="." && $file!="..") {
if(is_dir($dirToRead.$file))
$dirs[]=$dirToRead.$file;
else
$files[]=$file;
}
}
closedir($path4);
// get the next level up for the
$upDir = substr( $dirToRead, 0, strrpos( $dirToRead, '/') );
if( strrpos( $dirToRead, '/') + 1 == strlen("$dirToRead"))
$upDir = substr( $upDir, 0, strrpos( $upDir, '/') );
if($upDir==""){$upDir=def_path;}
echo "<pre>";
echo ltrim(substr_replace($dirToRead, ' ', 0, 1))."\n";
echo "<a href=\"?pass=$pass&path=$upDir\">..</a>\n";
if($dirs) {
natcasesort($dirs);
foreach($dirs as $dir)
echo "<a href=\"?pass=$pass&path=$dir\">" . basename($dir) . "</a>\n";
}

if ($dirToRead != def_path) {

I needed a function to offer me a list of files to select from. I used the codes from Marijan Greguric and Rick as a basis and got the following:
<script type="text/JavaScript">
function pokazi(dir){
x=document.getElementById(dir);
if(x.style.display == "none"){
x.style.display = "";
}else{
x.style.display = "none";
}
}
</script>
<?php
function ls($dir){
$handle = opendir($dir);
for(;(false !== ($readdir = readdir($handle)));){
if($readdir != '.' && $readdir != '..'){
$path = $dir.'/'.$readdir;
if(is_dir($path)) $output[$readdir] = $this->ls($path);
if(is_file($path)) $output[] = $readdir;
}
}
closedir($handle);
return isset($output)?$output:false;
//closedir($handle);
}
function throwtree ($dir, $name, $base='', $id='', $return = '') {
foreach ($dir as $key=>$node) {
$return .= "<dl style=\"border: none; margin:2px;\">";
if (is_array ($node)) {
$return .= "<dt><a href=\"#\" onClick=\"pokazi('$base$key');return false;\">$key</a></dt><dd style=\" margin-left:20px; display:none;\" id=\"$base$key\">";
$nextID = $base."/".$key;
$nextBase = "$base$key";
$this->throwtree ($node, $name, $nextBase, $nextID, &$return);
$return .= "</dd>";
} else {
$return .= "\n<dt><input name=\"$name\" type=\"radio\" value=\"$id/$node\"> $node</dt>\n";
}
$return .= "</dl>";
}
return $return;
}
?>
They are currently in a class, so you might have to edit the $this-> in the recursions.
The first function ls still creates an array as in the original; the throwtree function uses that array and creates nested defintion-lists of the file- and directory-tree. Nodes can still be folded using JavaScript from Marijan.
The function takes an additional parameter $name from which it generates a list of radio buttons; one per file listed. The values are the paths and file names of the files.
The HTML-String validates; as of now, the JavaScript doesn't degrate gracefully, though. I didn't bother to sort to the array before parsing it, either.
I haven't tested it much yet, but so far it looks good.
Use like this:
<?php
$myclass->throwtree ($myclass->ls ('path/to/files'), 'radioValue');
?>

Upgrade of davistummer's code :
You can now list your folder by date
you need to rename your file with this syntax :
"name_-_YYYY-mm-dd.ext"
<?php
function trierdossier($dirname, $sortby, $sortdir) {
$ext = array("jpg", "png", "jpeg", "gif", "pdf", "doc", "txt", "xls");
$files = array();
if($handle = opendir($dirname)) {
while(false !== ($file = readdir($handle))){
for($i=0;$i<sizeof($ext);$i++){
if(stristr($file, ".".$ext[$i])){ //NOT case sensitive: OK with JpeG, JPG, ecc.
$filesize = filesize($dirname . "/" . $file);
$date3 = explode("_-_",$file);
$date2 = explode(".pdf",$date3[1]);
$date1 = $date2[0];
$date0 = tostamp($date1);
if($filesize){
$files[] = array(
"name" => $file,
"size" => $filesize,
"date" => $date0
);
}
}
}
}
closedir($handle);

//obtain an array of columns
foreach ($files as $key => $row) {
$name[$key] = $row['name'];
$size[$key] = $row['size'];
$date[$key] = $row['date'];
}
return array_multisort($$sortby, $sortdir, $files) ? $files : false;
}
//end
?>
<?php
//affichage
$sortby = "date"; // sort-by column; accepted values: name OR width OR height OR size
$path = "../upload/argumentaires/lcp/"; // path to folder

moogman,
While using your excellent readdirsort function, php complains that the next element in the $items array could not be found.
Instead of:
if ($items[$last_read_item] == false)
Just use:
if (!isset($items[$last_read_item]) || $items[$last_read_item] == false)

To Marijan Greguric

In your script there is a little bug with folders with same name but different path :
i think that is correct to use this id
$id="$path$file";
and not
$id="$file";

Took cart at kolix dot de's wrapper and changed it into a simple readdir wrapper that does the same, but puts directories first and sorts. Hope it's useful :)
function readdirsort($dir) {
/* Funktastic readdir wrapper. Puts directories first and sorts. */
static $not_first_run, $last_read_item=0, $items;
if (!$not_first_run) {
$not_first_run = true;
while (false !== ($file = readdir($dir))) {
if (is_dir("$file"))
$dirs[] = $file;
else

natcasesort($dirs);
natcasesort($files);
$items = array_merge($dirs, $files);

Based on tips above, I made this function that displays all php files in your whole website, like a tree. It also displays which directory they're in.
$dir = $_SERVER['DOCUMENT_ROOT'];
$shell_command = `find $dir -depth -type f -print`;
$files = explode ("\n", $shell_command);
foreach ($files as $value)
{
$fileInfo = pathinfo($value);
$extension = $fileInfo["extension"];
if ($extension == "php")
{
$cur_dir = str_replace($_SERVER['DOCUMENT_ROOT'], "", dirname($value));
if ($cur_dir != $old_dir)
{
echo "<p><b>" . $cur_dir . "</b></p>";
$old_dir = $cur_dir;
}
echo $cur_dir . "/" . basename($value) . "<BR>";
}
}
You can change it to take input of certain directory or files of certain, or no extension.

After hours of work I found an error in the sort routine sumitted. The correction lies in the fact you need $path.$file to diffirentiate from [dir] or [file] in the routines
$path = "music/Holly Dunn/";
$dh = opendir($path);
while (false !== ($file=readdir($dh)))
{
if (substr($file,0,1)!=".")
{
if (is_dir($path.$file))
$dirs[]=$file.'/';
else
$files[]=$file;

$files=array_merge($dirs,$files);
foreach ($files as $file)

wrote this piece. I use it to validate my $_GET variables.
It firsts gets the variable $page, cheks if that variable is assinged (on the main index, it is not).
if it is assinged, it checks if it equals one of the found directory's, and then i assigns the variable definatly.
this is a rather secure way of validating the $_GET variable, which on my site should only have the name of one of my directory's.
<?php
$page = $_GET['a'];
if ($page != "" || !empty($page))
{
$handle=opendir('albums');
while (false!==($file = readdir($handle)))
{
if (substr($file,0,1)!=".") //do not look up files or directory's which start with a dot
{
if(!eregi("thumb",$file)) // all files and dir's containign the word thumb are filtred out
{
$path = "albums/" . $file;
if(is_dir($path)) // only directory's will get listed
{
if($page != $file) die("wrong argument! only a existing album may be set"); // validates input
else
{
$page = "albums/" . $page;
$thumb = $page . thumb;
}
}
}

to ES:
i believe you are mistaken. readdir() returns a string (the filename), not an array
therefor, the open_dir function should be like this:
function open_dir($dir) {
$this->dir = $dir;
$handle = opendir($this->dir);
if($handle) {
while(false !== ($file = readdir($handle)) {
if($file != "." && $file != "..") {
$files[] = $file;
}
}
sort($files);
foreach($files as $file) {
echo $file."<br>";
}
}

To beanz at gangstersonline dot co dot uk, just a little optimization tip.
You have make a lot of eregi calls in a sequence of elseif statements. That means that for a worst case, you'll be making 8 eregi calls per iteration. Instead of using a bunch of conditional eregi() calls (which is much slower compared to preg_match or strpos), you could do the following:
<?php
if ($i)
//create a mapping array
$ext_map = array('exe' => 'exe', 'bmp' => 'image1', etc....)
foreach($tab as $rep) {
//use one preg_match to grab the extention
if (preg_match('/\.([a-z]+)$/', $rep, $matches) {
$ext = $ext_map[$matches[1]];
} else {
$ext = 'text';
}
//rest of code...
}
?>
So instead of a worst case of n eregi calls per iteration, you're guaranteed only one preg_match per call. Or possibly even faster than preg_match:
$ext = $ext_map[substr($rep, strrpos($rep, '.'))];

Alex's example was really good except for just one small part that was keeping it from displaying directories above files in alphabetical order (His has makes the directories and files mixed)
I changed 'if (is_dir($path.$file))' to 'if (is_dir($file))' and it works perfectly now. Here's the whole block.
<code>
$path = $_SERVER[DOCUMENT_ROOT];
$dh = @opendir($path);
while (false !== ($file=@readdir($dh)))
{
if (substr($file,0,1)!=".")
{
if (is_dir($file))
$dirs[]=$file.'/';
else
$files[]=$file;
}
}
@closedir($dh);
if ($files)
natcasesort($files);
if ($dirs)
natcasesort($dirs);
$files=array_merge($dirs,$files);
foreach ($files as $file)
echo "<a href=$file>$file</a><br />";

I used nagash's script from below fo myself, and enhanced it.
It will now first display all folders sorted, and THEN all files sorted. Just like windows :-)
There is also a small function for hiding secret files.
Just set $rootdir to 1 in the root dir, and leave it 0 in all subdirs.
<?
$the_file_array = Array();
$the_folder_array = Array();
$handle = opendir('./');
while (false !== ($file = readdir($handle))) {
if ($file != ".") {
if (filetype($file) == "file") { $the_file_array[] = $file; } else if (filetype($file) == "dir") {$the_folder_array[] = $file; }
}
}
closedir($handle);
sort ($the_file_array);
reset ($the_file_array);
sort ($the_folder_array);
reset ($the_folder_array);
while (list ($key, $val) = each ($the_folder_array)) {
if (($val != ".") && (!fnmatch("*.php*", $val))) {
if ((fnmatch("~*", $val)) || (fnmatch("~some_thing", $val))) {
// CASE: An outcommented file. - Syn: "~<filename>" - Exp: "~nottobeseen.txt"
echo "** SECRET FILE **<br>";
}else{
if ($val == "..") {
if ($rootdir == "1") {
// CASE: Don't show the way upward if this is the root directory.
// Root Directory, do nothing.
}else{
// CASE: Show the ".." to go back if this is NOT the root directory.
echo '<a href="'.$val.'/">/'.$val.'/</a><br>';
}
}else{
// CASE: All normal folders. No ".." and no ".".
echo '<a href="'.$val.'/">/'.$val.'/</a><br>';
}
}
}
}
while (list ($key, $val) = each ($the_file_array)) {

IT IS VITALLY IMPORTANT that when using opendir and then scanning with readdir, that you test opendir to see if it has returned a valid pointer.
The following code does not :
<?php
$dir = opendir($mydir);
while((false!==($file=readdir($dir))))
if($file!="." and $file !="..")
unlink($mydir.'/'.$file);
closedir($dir);
?>
if $mydir is not a valid directory resource (for example, the directory in question has been deleted), then the code will loop infinitely. Of course, it'll stop eventually if you have set a max execution time, but in the meantime it will visibly slow the server.

here is a simple directory navigating script i created. files and directories are links and it displays the current directory and the path relative to the file the script is in. it also has a nifty 'up one level' link.
------
<?php
$path = $_GET['path'];
if(!isset($path))
{
$path = ".";
}
if ($handle = opendir($path))
{
$curDir = substr($path, (strrpos(dirname($path."/."),"/")+1));
print "current directory: ".$curDir."<br>************************<br>";
print "Path: ".dirname($path."/.")."<br>************************<br>";
while (false !== ($file = readdir($handle)))
{
if ($file != "." && $file != "..")
{
$fName = $file;
$file = $path.'/'.$file;
if(is_file($file))
{
print "[F] <a href='".$file."'>".$fName."</a> ".filesize($file)." bytes<br>";
}
if(is_dir($file))
{
print "[D] <a href='ex2.php?path=$file'>$fName</a><br>";
}
}
}
$up = substr($path, 0, (strrpos(dirname($path."/."),"/")));
print "[^] <a href='ex2.php?path=$up'>up one level</a><br>";
closedir($handle);
}
?>
------ sample output ------
current directory: kate
************************
Path: ./kate
************************
[F] xyz_file.txt 13005 bytes
[F] mno_file.txt 26327 bytes
[F] abc_file.txt 8640 bytes

Everyone seems to be using recursion for trawling through subdirectories. Here's a function that does not use recursion.
<?php
function list_directory($dir) {
$file_list = '';
$stack[] = $dir;
while ($stack) {
$current_dir = array_pop($stack);
if ($dh = opendir($current_dir)) {
while (($file = readdir($dh)) !== false) {
if ($file !== '.' AND $file !== '..') {
$current_file = "{$current_dir}/{$file}";
if (is_file($current_file)) {
$file_list[] = "{$current_dir}/{$file}";
} elseif (is_dir($current_file)) {
$stack[] = $current_file;
}
}
}
}
}
return $file_list;
}
?>
I also did a rudimentary benchmark against Rick's function (no reason in particular why I chose Rick's, it was just the latest) and the result is that using recursion results in about 50% longer execution time.
Details of benchmark:
Directory contains 64 subdirectories and about 117,000 files. Each function was executed 100 times in a for-loop and the average time per iteration was calculated. The result is 3.77 seconds for the non-recursive function and 5.65 seconds for the recursive function.

Yet another recursive directory lister :P
Why did I create it?
I like to keep things small, and it seems like all the scripts around here are a lot bigger and more complex while they produce the same (or nearly the same) output.
This one creates a multidimensional array with the folders as associative array and the files as values.
It puts the name of the folders and files in it, not the complete path (I find that annoying but its easy to change that if you prefer it with the path).
And I used a for loop instead of a while loop like everyone around here does.
Why?
1. I just like for loops.
2. Everyone else uses a while loop.
<?php
function ls($dir){
$handle = opendir($dir);
for(;(false !== ($readdir = readdir($handle)));){
if($readdir != '.' && $readdir != '..'){
$path = $dir.'/'.$readdir;
if(is_dir($path)) $output[$readdir] = ls($path);
if(is_file($path)) $output[] = $readdir;
}
}
return isset($output)?$output:false;
closedir($handle);
}
print_r(ls('.'));
?>
PS: if you don't need the files in it then you can just comment out the "if(is_file....." part.

sort ($the_array);
reset ($the_array);
while (list ($key, $val) = each ($the_array)) {
echo "<a href=prace.php?id=$val>$val</a><br>";

Simplified recursive directory listing. Returns FolderListing object which contains an array with all the directories and files.
<?php
class FolderListing {
var $newarr = array();
function loop($stack) {
if(count($stack) > 0) {
$arr = array();
foreach($stack as $key => $value) {
array_push($this->newarr, $stack[$key]);
if ($dir = @opendir($stack[$key])) {
while (($file = readdir($dir)) !== false) {
if (($file != '.') && ($file != '..')) {
array_push($arr, $stack[$key].'/'.$file);
}
}
}
closedir($dir);
}
$this->loop($arr);
} else {
$sorted = sort($this->newarr);
return($sorted);
}
}
}
$start = new FolderListing;
$base = array("baseDir");
$start->loop($base);
foreach($start->newarr as $value) {
echo $value."<br />";
}
?>
Add the following code around the array_push line to just check for directories:
if(is_dir($stack[$key].'/'.$file)) {
}

Whilst writing a script to check a directory to see whether certain files existed, I used an original example from this page and modified so that in the first loop that checks the directory, there is a second that looks at a database recordset and tries to find the matches.
I found an issue that I have not yet solved. I am not a PHP guru, so I might be missing something here.
In the parent loop, $file is set correctly. As soon as your progress to the inner loop, $file becomes just a full stop (.) - I've no idea why.
<?
if ($handle = opendir($path)) :
while (false !== ($file = readdir($handle))) :
// Here $file is set correctly
while($row = @ mysql_fetch_array($result)) :
// Here $file is set to .
endwhile;
endwhile;
closedir($handle);

If you want to walk through a directory and want to use a callback function for every dir or file you get you can use this
its like the perl File::Find method "find"
<?php
function find($callback, $dir=Array())
{
foreach($dir as $sPath) {
if ($handle = opendir($sPath)) {
while (false !== ($file = readdir($handle))) {
if($file !== "." && $file !== "..") {
if(is_dir($sPath."/".$file)) {
eval("$callback(\"$sPath\", \"$file\");");
find($callback, Array($sPath."/".$file));
} else {
eval("$callback(\"$sPath\", \"$file\");");
}
}
}
closedir($handle);
}
}
}
function walk($dir, $file)
{
print ">>> $dir/$file\n";
}
find("walk", Array("/etc"));
?>

After looking for awhile for a function which retrieves a folder listing based on certain criteria (return folder, files, or both; search recursively or not), I decided to write my own. Maybe somebody out there will find it helpful.
Currently, it returns a flat list, but that can changed to return a nested list by editing the line:
$file_list = array_merge($file_list, directory_list($path ...
to
$file_list[] = directory_list($path ...
function directory_list($path, $types="directories", $recursive=0) {
// get a list of just the dirs and turn the list into an array
// @path starting path from which to search
// @types can be "directories", "files", or "all"
// @recursive determines whether subdirectories are searched
if ($dir = opendir($path)) {
$file_list = array();
while (false !== ($file = readdir($dir))){
// ignore the . and .. file references
if ($file != '.' && $file != '..') {
// check whether this is a file or directory and whether we're interested in that type
if ((is_dir($path."/".$file)) && (($types=="directories") || ($types=="all"))) {
$file_list[] = $file;
// if we're in a directory and we want recursive behavior, call this function again
if ($recursive) {
$file_list = array_merge($file_list, directory_list($path."/".$file."/", $types, $recursive));
}
} else if (($types == "files") || ($types == "all")) {
$file_list[] = $file;
}
}
}
closedir($dir);
return $file_list;
} else {
return false;
}
}

This will allow you to print out a total recursive directory listing no files just directories for possible tree menues that need folder lists.
<?php
$DirectoriesToScan = array(realpath('/var/www/axim.caspan.com/Software/'));
$DirectoriesScanned = array();
while (count($DirectoriesToScan) > 0) {
foreach ($DirectoriesToScan as $DirectoryKey => $startingdir) {
if ($dir = @opendir($startingdir)) {
while (($file = readdir($dir)) !== false) {
if (($file != '.') && ($file != '..')) {
$RealPathName = realpath($startingdir.'/'.$file);
if (is_dir($RealPathName)) {
if (!in_array($RealPathName, $DirectoriesScanned) && !in_array($RealPathName, $DirectoriesToScan)) {
$DirectoriesToScan[] = $RealPathName;
$DirList[] = $RealPathName;
}
}
}
}
closedir($dir);
}
$DirectoriesScanned[] = $startingdir;
unset($DirectoriesToScan[$DirectoryKey]);
}
}
$DirList = array_unique($DirList);
sort($DirList);
foreach ($DirList as $dirname) {
echo $dirname."<br>";
}

I don't know if I haven't had the patience to go trough enough notes, but I didn't find any tip on how to recurively get a directory listing (show subdirectories too), so, as many other, I wrote one. Hopefully this will help someone.
<?php
function direcho($path) {
if ($dir = opendir($path)) {
while (false !== ($file = readdir($dir))){
if (is_dir($path.$file)) { // if it's a dir, check it's contents too
if ($file != '.' && $file != '..') { // ...but dont go recursive on '.' and '..'
echo '<li><b>' . $file . '</b></li><ul>';
direcho($path.$file); // This is a feature that surprised me, it IS possible to call
// the function itself from inside that function.
echo '</ul>';
}
else { //if it IS '.' or '..' , just output.
echo '<li><b>' . $file . '</b></li>';
}
}
else { //if it's not a dir, just output.
echo '<li>' . $file . '</li>';
}
}
closedir($dir);
}
}
direcho('/path/to/home/dir/'); // somehow only the absolute path ('/home/yourhomedir/public_html/testdir/') worked for me...

An extension to the sorted file list in a drop-down box posted by paCkeTroUTer at iprimus dot com dot au.
Takes the directory, the "name" of the form element it produces, and optionally, a filename. If the file name is in the list, it will be the default selection in the list.
<?
function listfiles($directory, $select_name, $selected = "") {
if ($dir = @opendir($directory)) {
while (($file = readdir($dir)) !== false) {
if ($file != ".." && $file != ".") {
$filelist[] = $file;
}
}
closedir($dir);
}
echo "<select name=\"$select_name\">";
asort($filelist);
while (list ($key, $val) = each ($filelist)) {
echo "<option value=\"$val\"";
if ($selected == $val) {
echo " selected";

I use the function below in my site, is good if you wanna only images files on the filename array.
function GetFileList($dirname, $extensoes = FALSE, $reverso = FALSE)
{
if(!$extensoes) //EXTENSIONS OF FILE YOU WANNA SEE IN THE ARRAY
$extensoes = array("jpg", "png", "jpeg", "gif");
$files = array();
$dir = opendir($dirname);
while(false !== ($file = readdir($dir)))
{
//GET THE FILES ACCORDING TO THE EXTENSIONS ON THE ARRAY
for ($i = 0; $i < count($extensoes); $i++)
{
if (eregi("\.". $extensoes[$i] ."$", $file))
{
$files[] = $file;
}
}
}
//CLOSE THE HANDLE
closedir($dirname);
//ORDER OF THE ARRAY
if ($reverso) {
rsort($files);
} else {
sort($files);
}
return $files;

Why not sorting by filemtime like this?
$handle=opendir($fPath);
while ($file = readdir($handle))
{
if($file=='.'||$file=='..')
continue;
if (preg_match("/\.(esp|xml)$/", $file)){
$filetlist [$file] = filemtime ($fPath.'/'.$file);
}
}
asort($filetlist);
while (list ($key, $val) = each ($filetlist))
{
echo $key;

On sorting by date- no, you can't just use an associative array since some things /will/ be created on the same second. No reason why you can't append the filename to the time, though! (used md5() to kill any weird characters in a unique way)
$dirpath = getcwd() . "/";
$dir = opendir($dirpath);
$files = array();
while ($file = readdir($dir)) {
$localpath = $dirpath.$file;
if (is_file($localpath)) {
$key = filemtime($localpath).md5($file);
$files[$key] = $file;
}
}
ksort($files);
foreach ($files as $file) {
echo "$file<br>";
}

This is an example of how to sort directories alphabetically into a drop down list:
<?
if ($dir = @opendir("products"))
{
while (($file = readdir($dir)) !== false)
{
if($file != ".." && $file != ".")
{
$filelist[] = $file;
}
}
closedir($dir);
}
?>
<form>
<select name="selected_dir" >
<?php
asort($filelist);

{
echo "<option>$val</option>";
}
?>
</select>

Here is a function that will recursively copy a file into every directory within a specified directory, unless the directory is in an optional third parameter, an array with a list of directory names to skip. It will also print whether it copied each item it expected to.
Also, if you try to copy a file to itself in PHP, you end up with an empty file. To alleviate this, there is a fourth parameter, also optional, which is the number of levels to skip when copying files. The default is 0, which will only skip the directory specified in $dir, so that a call using the file's directory will work properly. I would not recommend calling this function with a directory higher up the tree than $file's.
<?php
function copyintodir ($file, $dir, $skip = array(''), $level_count = 0) {
if (count($skip) == 1) {
$skip = array("$skip");
}
if (!@($thisdir = opendir($dir))) {
print "could not open $dir<br />";
return;
}
while ($item = readdir($thisdir) ) {
if (is_dir("$dir/$item") && (substr("$item", 0, 1) != '.') && (!in_array($item, $skip))) {
copyintodir($file, "$dir/$item", $skip, $level_count + 1);
}
}
if ($level_count > 0) {
if (@copy($file, "$dir/$file")) {
print "Copied $file into $dir/$file<br />\n";
} else {
print "Could not copy $file into $dir/$file<br />\n";
}
}
}
?>
You can call it using a function call such as this:
copyintodir ('index.php', '.', 'images');

Yet another recursive directory listing script. This one returns a list of all absolute filenames (files only, no directories) in or below the directory first specified in $DirectoriesToScan.
$DirectoriesToScan = array(realpath('.'));
$DirectoriesScanned = array();
while (count($DirectoriesToScan) > 0) {
foreach ($DirectoriesToScan as $DirectoryKey => $startingdir) {
if ($dir = @opendir($startingdir)) {
while (($file = readdir($dir)) !== false) {
if (($file != '.') && ($file != '..')) {
$RealPathName = realpath($startingdir.'/'.$file);
if (is_dir($RealPathName)) {
if (!in_array($RealPathName, $DirectoriesScanned) && !in_array($RealPathName, $DirectoriesToScan)) {
$DirectoriesToScan[] = $RealPathName;
}
} elseif (is_file($RealPathName)) {
$FilesInDir[] = $RealPathName;
}
}
}
closedir($dir);
}
$DirectoriesScanned[] = $startingdir;
unset($DirectoriesToScan[$DirectoryKey]);

This is a good way to put all your files from a directory in an arry, and echo them on your page.
<?php
$the_array = Array();
$handle = opendir('.');
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") { /* as descripted below: these "files" will not be added to the array */
$the_array[] = $file;
}
}
closedir($handle);
foreach ($the_array as $element) {
echo "$element @br /@ \n";
}

function walk_dir($path)

if ($dir = opendir($path)) {
while (false !== ($file = readdir($dir)))
{
if ($file[0]==".") continue;
if (is_dir($path."/".$file))
$retval = array_merge($retval,walk_dir($path."/".$file));
else if (is_file($path."/".$file))
$retval[]=$path."/".$file;
}
closedir($dir);

return $retval;

While I won't make any claims as to its efficiency, this modified version of me@infinito.dk's script above does do several things the previous one doesn't. It will display jpegs using the .jpeg extension, and will not show double-extended files (foo.jpg.bar), nor will it show non-image files with an extension in their name, like mygif.html.
<?
function CheckExt($filename, $ext) {
$passed = FALSE;
$testExt = "\.".$ext."$";
if (eregi($testExt, $filename)) {
$passed = TRUE;
}
return $passed;
}
//Define an array of common extensions.
$exts = array("gif","jpg$|\\.jpeg","png","bmp");
echo "<b>Images in this folder:</b>";
$dir = opendir(".");
$files = readdir($dir);
while (false !== ($files = readdir($dir))) {
foreach ($exts as $value) {
if (CheckExt($files, $value)) {
echo "<a href=\"$files\">$files</a>\n";
$count++; //Keep track of the total number of files.
break; //No need to keep looping if we've got a match.
}
}
}
echo $count." image(s) found in this directory.\n";
echo "<a href=\"".$_SERVER["PHP_SELF"]."\">Refresh</a>\n";
//Be a good script and clean up after yourself...
closedir($dir);

Mod'ed the code a bit. Made it so the dir is selected by dir.php?dir=name . I made it to parse anything starting with "/" "." or "./" so there shouldn't be any security risks when using this.
<?php
$directory = $_REQUEST["dir"]; // lets fetch the variable: REQUEST works for both, POST and GET methods
if (substr($directory, 0, 1) == "/")
$directory = "";
$directory = str_replace ("./", "", $directory);
$directory = str_replace (".", "", $directory);
if ($directory != @$null) { // lets check if the variable "dir" has something in it, otherwise lets just print out the empty document
if ($dir = @opendir($directory)) { // changed "./" to the directory variable
echo ("Listing contents of <b>$directory</b><br><br>\n"); // i just added this thing
while (($file = readdir($dir)) !== false) {
if ($file != "." && $file != "..") {
$location = "$directory/$file";
$type = filetype($location);
$size = filesize($location);
if (is_dir($location) == true) {
echo ("$type - <a href=\"dir.php?dir=$location\">$file</a><br>\n");
}
else {
echo ("$type - <a href=\"$location\">$file</a> - $size Bytes<br>\n");
}
}
}
closedir($dir);
}
}

Sometimes happens that you need to sort your files by date , but using associative arrays you won't be able to list files that were written in the same second (rarely , but with CMS system it's strangely frequent , doh!). Here's something that may come in hand in such a case. Code CAN really be improved (especially flags), but you can figure out the trick.
$dir = opendir($myDir);
while (($file = readdir($dir)) !== false) {
if ($file != "." and $file != "..") {
$fileTime=filemtime($docsPath.$file);
$stillExists = true;
while ($stillExists) {
$stillExists = validateTs($fileTime);
if (!$stillExists) {
$articlesToProcess[$fileTime] = $file;
}
else {
echo("<font color=\"red\" size=\"3\">found ts equals to another key. add 1 second and retry </font><br>");
$fileTime++;
}
}
}
}
krsort($articlesToProcess);
# Follow function that do the work
function validateTs($fileTime) {
global $articlesToProcess;
foreach($articlesToProcess as $key => $value) {
if ($fileTime == $key) {
return true;
}
}
return false;
}

to skip hidden files ( on unix ), you can do:
$d = opendir('/path/to/dir');
while(($f = readdir($d)) !== false)
{
if($f[0] == '.')
continue;

I tried to find a script that would put all files of one directory($img_path) into an array while excluding any subdirectory, not only ".", ".." or "xyz".
Chriss found the solution some threads above.
The following way the slashes are used work for both- LINUX and WIN:
$handle = opendir("$img_path");
while (false !== ($file = readdir($handle))) {
if(is_file($img_path."//".$file)) {
$filelist[] = $file;
$anz_files = count($filelist);
}
}

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!

One little note about the is_dir() and is_file() functions when used with readdir().
You better use the fully qualified name when testing, otherwise you could get undesired behavior.
This is the way I'm reading the files form a directory and it is working perfectly.
function get_dir($path)
{
if ($dir = opendir($path)) {
/* This is the correct way to loop over the directory. */
while (false !== ($file = readdir($dir)))
{
if (!is_dir($path.$file))
{
//... Your Code Here
}
}
closedir($dir);
}
return // whatever you want to return, an array is very usefull
}
Hope this can help,

It generates and displays a sorted list of all directories, sudirectories and files of your HD.

if (is_dir($path.'\\'.$file))
$d[$nd++]=$file;
else
$f[$nf++]=$file;
}
closedir($hndl);
sort($d);
sort($f);
$n=1;
for ($i=0;$i<count($d);$i++)
{
GetFileList($path.'\\'.$d[$i].'\\', $a[$n]);
$a[$n++][0]=$d[$i];
}
for ($i=0;$i<count($f);$i++)
{
$a[$n++]=$f[$i];
}

@dwalet@po-box.mcgill.ca
To search for some specific file or file extension:
Make sure that you put this expression
if (ereg("\.sql",$file)) instead of (eregi(".sql",$file)) since the ereg function is familiar with regular expressions
and "the point" (any char) represents a special reg expr. (have a look at reg expr. if you are interested!)
You can combine in the if expression whatever you want for instance if (ereg("\.sql",$file)) && (strlen($file))<100 )
:) of course this doesn't make sooo much sense to use a strlen here, but however this should only be a demonstration
Now the next thing...
Speed issue :
Since the ereg() is capable of reg expr. this means a high speed decrease for you.
So for this simple fileextension search function use the strstr() function instead... which hasn't the power of reg expr. but boast of speed
At least your "if expression" should look something like that: if(stristr($file,".sql"))

funny thing ;)
if you really read your dirs with subdirs into an array like described above, and there's a link like
ln -s ./ ./recursive
you'll get an endless loop ;)
My suggestion to prevent this is to limit the number of recursion instances: Change the function to
function GetDirArray($sPath,$maxinst,$aktinst = 0)
{
//Load Directory Into Array
$handle=opendir($sPath);
while ($file = readdir($handle))
{ $retVal[count($retVal)] = $file; }
//Clean up and sort
closedir($handle);
sort($retVal);
while (list($key, $val) = each($retVal))
{
if ($val != "." && $val != "..")
{
$path = str_replace("//","/",$sPath.$val);
if (is_dir($sPath.$val) && ($aktinst < $maxinst || $maxinst == 0))
{ GetDirArray($sPath.$val."/",$maxinst,$aktinst+1); }
}
}
}
A call could be this:
$dir = GetDirArray("./",0);
Another method could be a regexp, which looks for more than $maxinst same named subdirs:
if (is_dir($sPath.$val) && !preg_match("/\/(\w+)(\/\\1){$max,}/",$sPath.$val))
{ GetDirArray($sPath.$val."/",$maxinst); }
instead of the if-construction above.
