XXVI. Directory FunctionsNo external libraries are needed to build this extension. There is no installation needed to use these
functions; they are part of the PHP core. This extension has no configuration directives defined in php.ini.
The constants below are defined by this extension, and
will only be available when the extension has either
been compiled into PHP or dynamically loaded at runtime.
Note:
The PATH_SEPARATOR was introduced with PHP 4.3.0-RC2.
- Table of Contents
- chdir -- Change directory
- chroot -- Change the root directory
- dir -- Directory class
- closedir -- Close directory handle
- getcwd -- Gets the current working directory
- opendir -- Open directory handle
- readdir -- Read entry from directory handle
- rewinddir -- Rewind directory handle
- scandir -- List files and directories inside the specified path

Here is a very short function to return all files inside a dir with full pathname
<?php $myfiles=GetDirContents(dirname($_SERVER['DOCUMENT_ROOT']));
?>
<?php function GetDirContents($dir){
ini_set("max_execution_time",10);
if (!is_dir($dir)){die ("Fehler in Funktion GetDirContents: kein gültiges Verzeichnis: $dir!");}
if ($root=@opendir($dir)){
while ($file=readdir($root)){
if($file=="." || $file==".."){continue;}
if(is_dir($dir."/".$file)){
$files=array_merge($files,GetDirContents($dir."/".$file));
}else{
$files[]=$dir."/".$file;
}
}
}
return $files;
}

How to access shared drives in the network:
Is you are using IIS and want to access \\FILESERVER\SHARE_NAME\ and your web server is not a domain controler. You will need to make your webserver runs as a user from the same domain the FILESERVER belongs to.
As an example:
+ Create a new user called IUSR_<webserver> on the domain controler
+ Make this new user a member of the domain's guest group
+ Go to the Internet Information Services
+ Inside Properties, choose Directory Security
+ on Anonymous access and authentication control... edit
+ change the Account used for anonymous access to the new user created before. In our example: IUSR_<webserver>@<domain name>
After that you will need to take care of local security access. You will need to grant access for this new user on the webserver. Like if you use sessions you need to grant access to this user on the temp directory that your php is using.

Hi, I worked a lot with some usefull recursive functions and one "C pointer-like" approach using PHP. The result is a small code to read directories and files to generate an associative array.
I hope if this will be usefull for you as was to me. (Ah, sorry by my poor english!)
There it's the code:
function &walkThroughDir ($path,&$filelist)
{
if (!is_dir($path)) return NULL;
$resdir = @opendir ($path) or die("Error reading ".$path);
// It's the secret for this recursive function
$ret = &$filelist;
while ( ($entry=readdir($resdir))!==false ) {
if ( is_dir($path."/".$entry)=="dir" ) { //if it's a directory...
if ($entry!="." and $entry!="..") {//do not use ./ or ../
// Call himself using the same result array
walkThroughDir($path."/".$entry,$ret);
}//if
} else {
// if it is not a dir, read the filenames
$ret[$path][] = $entry;
}//if
}//while
closedir($resdir);
return $ret;
}//walkThroughDir
This function will generate something alike:
Array
(
[/Library/WebServer/Documents/component/test/subtest] => Array
(
[0] => linuxitscool.php
)
[/Library/WebServer/Documents/component/test] => Array
(
[0] => macosxrulez.php
[1] => unixrulez.php
)
[/Library/WebServer/Documents/dev/component] => Array
(
[0] => Component.h.php
[1] => Component.pkg.php
)
)

what you really should be doing is urlencode()ing rather than manually replacing " " with "%20" and either turning off magic_quotes_gpc or using stripslashes() rather than manually replacing \' with '

David's script is great, but there are a few problems if you really want to use it. If you're worried about security you probably shouldn't use this anyways, but with David's code, an inquisitive person could manually send a uri that ends in "?moverse=../" and still move up a directory. Also, at least with the version of PHP on my server (unsure of version), any uri with a single quote (') would end up with a backslash preceding it. I think this is more to do with using the GET method instead of POST, but I haven't delved that deep. I also added some '\n' action for html readability and replaced whitespace with percentage codes.
<?php
$path = "./";
if (strrpos($moverse,'..')) {
$moverse = str_replace('/..','',$moverse);
$moverse = substr($moverse,0,strrpos($moverse,'/'));
}
if (strpos($moverse,'..')===false) { } else if (strpos($moverse,'..')==0) {
echo '<span style="font-size: 150%;"><b>Bad Hacker = No caffeine</b></span>';
$moverse="";
}
if($moverse) {
$moverse = $moverse."/";
if (strpos($moverse,"\'")) { $moverse = str_replace("\'","'",$moverse);
}
}
echo $moverse."<br/>"."\n";
$handle=opendir($path.$moverse);
while ($file = readdir($handle)) {
if(is_dir($path.$moverse.$file) && $file != ".") {
if ($file == ".." && $moverse == "") {
} else {
$uri=str_replace(" ","%20",$moverse.$file);
echo '<a href="?moverse='.$uri.'">'.$file.'</a><br/>'."\n";
}
} else if ($file != "." && $file != "index.php") {
$uri=str_replace(" ","%20",$path.$moverse.$file);
echo '<a href="'.$uri.'">'.$file.'</a><br/>'."\n";
}
}
?>

a little juiced up version of turgon64´s script.
before the $moverse was getting very long if you where doing a lot of moving around in directorys and also i was unable to open files.
also, now you´re not able to move above the specified path
<?php
$path = "./";
if (strrpos($moverse,'..')) {
$moverse = str_replace('/..','',$moverse);
$moverse = substr($moverse,0,strrpos($moverse,'/'));
}
if($moverse) $moverse = $moverse."/";
echo $moverse.'<br>';
$handle=opendir($path.$moverse);
while ($file = readdir($handle)) {
if(is_dir($path.$moverse.$file) && $file != ".") {
if ($file == ".." && $moverse == "") {
} else {
echo "<a href='?moverse=".$moverse.$file."'>".$file."</a><br>";
}
} else if ($file != ".") {
echo "<a href='".$path.$moverse.$file."'>".$file."</a><br>";
}
}

After some consideration, this seems to be the most concise and elegent method I can devise for recursively traversing a directory (i.e. all subdirectories as well). It returns an Array containing all entries. It DOES NOT require global variables either.
To make it return only other directories or only files, insert one of the following where indicated:
DIR ONLY OPTION 1: if(is_dir($full_path)){ $list[]=$full_path; }
FILE ONLY OPTION 2: if(is_file($full_path)){ $list[}=$full_path; }
function make_tree($path){ //where $path is your source dir.
$handle=opendir($path);
while($a=readdir($handle)){
if(!preg_match('/^\./',$a)){
$full_path="$path/$a";
$list[]=$full_path; // REPLACE WITH OPTION IF NEEDED.
if(is_dir($full_path)){
$recursive=make_tree($full_path);
for($n=0; $n<count($recursive); $n++){
$list[]=$recursive[$n];
}
}
}
}
closedir($handle);
return $list;
}
If conciseness is what you are after, the above is rock solid. However, beware of passing huge or unknown filesystem's paths as it can eat memory unless you impose a recursive level limit. The above can be very easily modified to limit recursive levels. See the below, limit-safe example.
function make_tree($path){ //where $path is your source dir.
$handle=opendir($path);
while($a=readdir($handle)){
if(!preg_match('/^\./',$a)){
$full_path="$path/$a";
$list[]=$full_path;
if((is_dir($full_path))&&(!preg_match('/(\/.+){6,}/',$full_path))){ //where {6,} is the maximum recursives
$recursive=make_tree($full_path);
for($n=0; $n<count($recursive); $n++){
$list[]=$recursive[$n];
}
}
}
}
closedir($handle);
return $list;
}

Just add my own script for manage directories
<?php
$path = "./";
if($moverse) { chdir ($moverse); }
$handle=opendir($path);
while ($file = readdir($handle)) {
if(is_dir($file)) {
if($moverse){ $moverse = $moverse."/"; }
echo "<a href='?moverse=".$moverse.$file."'>".$file."</a><br>";
}
else
{
echo "<a href='".getcwd()."/".$file."'>".$file."</a><br>";
}
}
?>
I hope it will be usefull.

Just to add my own tip on the above recursive_dirlist()... I would suggest to make the last few lines:
sort(&$getDirList_alldirs);
sort(&$getDirList_allfiles);
$retval['dirs'] = &$getDirList_alldirs;
$retval['files'] = &$getDirList_allfiles;
otherwise your dirlisting may not be exactly the way you want, especially if you are operating on files in these dirs, and order may be a factor (as it is in my project ;-) )

I searched around and couldn't find a decent function that JUST returned directories, not files. I couldn't get the ones here to work so i wrote my own.
<?php
function read_dir($path){
static $dir_arr = array () ;
$handle=opendir($path);
while ($file = readdir($handle)) {
if ($file != "." && $file != ".." && is_dir($path.$file)) {
$sub_dir = $path . $file . "/" ;
$dir_arr[] = $sub_dir ;
read_dir($sub_dir);
}
}
return $dir_arr ;
}
?>

I couldnt get the function by sc1n at yahoo dot com to work, so I modded it minorly to this:
function Fetch_File_Tree($start_directory)
{
if( $dir = @opendir($start_directory) )
{
$tree = array();
while( FALSE !== ($file = readdir($dir)) )
{
if($file != "." && $file != "..")
{
$absolute_file = $start_directory . $file;
if (is_file($absolute_file)) $tree[] = $file;
else if (is_dir($absolute_file)) Fetch_File_Tree($absolute_file."/");
}
}
}
else
{
return FALSE;
}
return $tree;
}
The @-sign is just for suppressing warnings.
Good luck!

The following function returns a tree of the directory structure from the given start point.
<?php
function Fetch_File_Tree($start_directory)
{
if( $dir = opendir($start_directory) )
{
$tree = array();
while( FALSE !== ($file = readdir($dir)) )
{
if($file != "." && $file != "..")
{
$absolute_file = $start_directory . $file;
is_file($absolute_file) ? $tree[] = $file : $tree[$file] = Fetch_File_Tree($absolute_file . "/");
}
}
}
else
{
return FALSE;
}
return $tree;
}

Heres mine modified from the original example:
function listdir($dir) {
function ls_recursive($dir) {
if (is_dir($dir))
{
$dirhandle=opendir($dir);
while(($file = readdir($dirhandle)) !== false)
{
if (($file!=".")&&($file!="..")) {
$currentfile=$dir."/".$file;
if (!$i) $i = 0;
$dir_array[$i] = $currentfile;
$i++;
if(is_dir($currentfile)) {
ls_recursive($currentfile);
}
}
}
}
return $dir_array;
}
$dir_array = ls_recursive($dir);
return $dir_array;
}

get a list of files and directories recursivelly without the use of global variables.
the difference between this one and piccaso at gmx dot net's, is that this one returns files inside the subdirectories as well (with full path) :
function recursive_listdir($base) {
static $filelist = array();
static $dirlist = array();
if(is_dir($base)) {
$dh = opendir($base);
while (false !== ($dir = readdir($dh))) {
if (is_dir($base ."/". $dir) && $dir !== '.' && $dir !== '..') {
$subbase = $base ."/". $dir;
$dirlist[] = $subbase;
$subdirlist = recursive_listdir($subbase);
} elseif(is_file($base ."/". $dir) && $dir !== '.' && $dir !== '..') {
$filelist[] = $base ."/". $dir;
}
}
closedir($dh);
}
$array['dirs'] = $dirlist;
$array['files'] = $filelist;
return $array;
}

I used the function without making any changes and did not get any output, no error though. then i realised the mistake and did the changes and got perfect output.
hope this helps someone in future.

Why, here's the millionth recursive directory listing script. The extra added bonus in this thing is, it lists the directories in a win-explorer-like fashion, with indentation according to hierarchical depth and such gizmos.
Using the variable $sf, you can control whether files should be displayed. If $sf == 0, only directories will be shown. This is useful if you just want to see the hierarchical structure of what's in that path.
The output must be encapsulated in "preformatted" tags, otherwise things will look wild. Directories are shown in "bold", the explorer-like watchamacallits that show you where you are, are "italic", so you'd best use CSS to overwrite the standard formatting so it looks good. I used this:
b {color:blue}
i {font-style:normal; color:gray}
This code can of course be greatly improved upon *hint* :)
<php?
function displaydir ($path, $depth) {
if (($d = @opendir ($path)) === false) echo ('[Could not open path:]');
else {
while ($f = readdir ($d)) {
if ($f != "." && $f != "..") {
if (is_dir ($path . "/" . $f)) {
for ($i = 0; $i < $depth - 1; $i++) echo '<i>| </i>';
echo '<i>+-</i>';
echo "<b>$f</b>\n";
$depth++;
displaydir ($path . "/" . $f, $depth);
$depth--;
} else {
if ($sf == 1) {
for ($i = 0; $i < $depth - 1; $i++) echo '<i>| </i>';
echo '<i>+-</i>';
echo "$f\n";
}
}
}
}
closedir ($d);
}
}

This script will count lines of code that do not begin with // or are not blank space. It's very approximate because it will include /* */ comments and will also include lines that start with blank space and then //. It's a start though (it's recursive, so don't use this with a directory structure that includes symbolic links). This will recursively count all the lines of files that end with .php. You can change .php to whatever, and also change the guidelines as to whether a line qualifies as a comment or not (look around the !="//" part)

In fancao0515@0451.com's function list_dir($dirname):
if(is_dir($dirname.$file))
list_dir($dirname.$file.'\\');
should become:
if(is_dir($dirname.$file))
