# opendir

(PHP 3, PHP 4, PHP 5)

opendir -- Открыть каталог

## Описание

resource opendir ( string path )

Возвращает дескриптор каталога для последующего использования с функциями closedir(), readdir() и rewinddir().

Если `путь` не существует или каталог, расположенный по указанному пути, не может быть открыт вследствие правовых ограничений или ошибок файловой системы, функция opendir() возвращает значение `FALSE` и генерирует сообщение PHP об ошибке уровня E_WARNING. Вы можете запретить вывод сообщения об ошибке, предварив имя функции opendir() символом '@'.

Пример 1. Пример использования функции opendir()

`<?php
$dir = "/tmp/";
// Открыть заведомо существующий каталог и начать считывать его содержимое
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
print "Файл: $file : тип: " . filetype($dir . $file) . "\n";
}
closedir($dh);
}
}
?>`

Начиная с версии `PHP 4.3.0`, параметр `путь` может также являться любым URL'ом, обращение к которому приводит к получению списка его файлов и каталогов. Однако, данный способ работает только при использовании url-упаковщика `file://`. В версии `PHP 5.0.0` была добавлена поддержка url-упаковщика `ftp://`.

`An issue that I ran into is that opendir() could care less if you've got server authentication set on sub directories and so any such authentication is bypassed completely when accesses in this way. I did solve it for my application of a pretty file manager, by redirecting to all sub directories thusly:
$fdir = "./subdirectory_I_want_to_visit/";
if ($fdir != './') { //basically where we are or the parent
//redirect the browser to force authentication check on any subdirectories
header("Location: http://my.domain.com".dirname($_SERVER["PHP_SELF"]).substr($fdir,2));
exit;
} else {
$dir = opendir($fdir);

`Pointing on the previous post, I'd like to say the following.
You can use opendir on all valid (existant and reachable) folders.
This counts not only for windows but also for linux.
Under linux, you can also read root folders etc.
To avoid access to non-public data, you should check the given parameter for opendir before executing opendir.
Let's say you have this:
/home/users/mrsmith/
/home/users/mrsmith/info.txt
/home/users/mrsmith/test/photo.jpg
/home/users/mradmin/private.txt
Now you don't want mrsmith to access mradmin's folders/files.
In that case you could/should define the path where the data MUST be inside.
Attention:
Don't check the data with substr though, it's not a secure solution.
Exploit example: /home/users/mrsmith/../mradmin/
Exploit example2: /home/users/mrsmith/../../../../../../../../../../../../../dev/
I'd do a case sensitive regex match.
So after the first folder there may not be a subfolder named ".." because that would jump one folder back.
I hope this isn't too offtopic or so but I think it's important to think of that when creating file systems.`

`Hello,
A friend of mine is running a webhost, I think i found a security leak with this script:
<?php
function select_files($dir, $label = "", $select_name, $curr_val = "", $char_length = 30) {
$teller = 0;
if ($handle = opendir($dir)) {
$mydir = ($label != "") ? "<label for=\"".$select_name."\">".$label."</label>\n" : "";
$mydir .= "<select name=\"".$select_name."\">\n";
$curr_val = (isset($_REQUEST[$select_name])) ? $_REQUEST[$select_name] : $curr_val;
$mydir .= ($curr_val == "") ? " <option value=\"\" selected>...\n" : "<option value=\"\">...\n";
while (false !== ($file = readdir($handle))) {
$files[] = $file;
}
closedir($handle);
sort($files);
foreach ($files as $val) {
if (is_file($dir.$val)) { // show only real files (ver. 1.01)
$mydir .= " <option value=\"".$val."\"";
$mydir .= ($val == $curr_val) ? " selected>" : ">";
$mydir .= (strlen($val) > $char_length) ? substr($val, 0, $char_length)."...\n" : $val."\n";
$teller++;
}
}
$mydir .= "</select>";
}
if ($teller == 0) {
$mydir = "No files!";
} else {
return $mydir;
}
}
echo select_files("C:/winnt/", "", "", "", "60");
?>
Now i can see hist files in his windows dir. Is this a leak? and is it fixable? I'll report this as bug too!

`oryan's example is still sub-optimal, even if people using it never ever substitute a variable for directory.
Just use PHP's glob() function, which will be faster and more efficient anyway since it doesn't have to launch a shell and run the ls program (that's what the shell_exec does).
$result = glob("directory/*");`

`There might be a bit of truth to that. If, by chance, the webmaster made a form saying "type a random directory name here" and used that in the function, there'd be a problem. So let's eliminate the 'function' part
$files=shell_exec("ls directory");
$result=explode("\n",$files);
'$result' will now be an array of the directory files. You can use variables in the shell_exec command, but don't use anything that could be user-sent.`

`The example given by oryan at zareste dot com may also be a "simpler faster way" of creating security holes in your code. The function listed above prevents risking execution of abitrary shell commands listed after a semicolon (;) in your directory name.
Example: $directory = '.;rm -rf /';
Result: List this directory, erase contents of filesystem.`

`There's a simpler faster way to get a whole directory if you're using PHP 4. This function uses shell_exec - http://us3.php.net/shell_exec - and assumes you're using Unix/Linux and have shell access -
function dir($directory){
$files=shell_exec("ls ".$directory);
return explode("\n",$files);
}
This returns an array with all the files.
This way, you can use modifiers like -t, which shows files in order of modification time ($files=shell_exec("ls -t ".$directory);). Enough tweaking and you can use it on Windows, though I can't say how since I don't have a Windows server to try it on`

`Here's another recursive function that prints out everything from the starting path to the end. It doesn't have any search function, but just another example. I wrote it for getting a quick hierarchial view of websites (even through Dreamweaver will show it to me, it'd be a chore to go through each folder and expand it).
<?php
// map_dirs(path,level)
// path, level to start (start at 0)
map_dirs("/var/ww/html/",0);
function map_dirs($path,$level) {
if(is_dir($path)) {
if($contents = opendir($path)) {
while(($node = readdir($contents)) !== false) {
if($node!="." && $node!="..") {
for($i=0;$i<$level;$i++) echo " ";
if(is_dir($path."/".$node)) echo "+"; else echo " ";
echo $node."\n";
map_dirs("$path/$node",$level+1);
}
}
}
}

`Note that the opendir() function will use ISO8859-1 characterset under windows...
If you have korean, japanese, etc.. filenames, you won't be able to open them. I still didn't find any solution to workaround that.`

`I whipped up a little recursive directory searching function that has been very useful. I figured it belonged here. I'm sure its not the most robust or creative code, but it works for me.
Note, you can use strpos for simple matches or preg_match if you want the power of regular expressions (however it is a bit slower). I also have it set to use double quotes "\\" for WIN32. change to "/" if necessary.
It returns an array of all matching files with full path.
function search_dir($mask,$dir,$level){
if($level > 3){
return "Exceeded max level (3)";
}
$return_me = array();
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
#echo "filename: $file : filetype: " . filetype($dir . $file) . " level: $level\n";
if(is_dir($dir."\\".$file) and $file != '.' and $file != '..'){
$test_return = search_dir($mask,$dir."\\".$file,$level+1);
if(is_array($test_return)){
$temp = array_merge($test_return,$return_me);
$return_me = $temp;
}
if(is_string($test_return)){
array_push($return_me,$test_return);
}
#} else if(strpos($file,$mask) !== FALSE){ #A bit faster, but you can't use regexs!
} else if(preg_match($mask,$file)){
array_push($return_me,$dir."\\".$file);
}
}
closedir($dh);
}
}
return $return_me;

`I had problems getting it to work because I'm not the best at PHP, but there IS a way to use opendir to list things in alphabetical order. I'm using it for my university project. All you have to do is read the filenames into an array, sort the array and then do what you want with the filenames.... like this....
So that you know what all my variables mean in this - $stats is the folder that it looks in for the files - for example
?stats=images
would look in the images folder
Obviously you will want to modify it so it fits your needs, but I thought you guys would want this - especially if your server doesnt have the latest version of php.
===========================
<?php
$i = 0;
$arraycount = 0;
$home="/home/cabal/public_html/b146/admin/$stats";
if ($stats)
{
$dircheck="/home/cabal/public_html/b146/admin/$stats";
if (is_dir($dircheck))
{
if ($handle = opendir($home))
{
while (false !== ($file = readdir($handle)))
{
if ($file != "." && $file != "..")
{
$path = "$home/$file";
$extension = array_pop(explode('.', basename($path)));
$filearray[$i] = $file;
$i++;
}
}
}
closedir($handle);
}
else
{
echo "INCORRECT SELECTION";
}
}
else
{
echo "NOTHING SELECTED";
}
echo "&nbsp;";
echo("<table width='100%' border='1'><tr><td><b><font color='#ff0000'>");
echo("$stats : Log File");
echo("</b></font></td><td><font color='#FF0000'><b>Page Views</b></font></td></tr>");
sort($filearray);
reset($filearray);
while (list($key, $val) = each($filearray))
{
$includearray = "$home/$filearray[$key]";
echo("<tr><td>");
echo("$val");
echo("</td><td>");
include($includearray);
echo("</td></tr>");

`If you have problems like "failed to open dir: Invalid argument"
when using IIS and trying to access windows/smb network shares, try
//servername/share/directory

`I ran into a little snag in example 1. opendir() lists files by the last time the file was accessed. I was trying to print the files numerically in a directory.
Solution: Use scandir() instead (php5) or store the files in an array and sort it.
Hope this helps someone.

`In addition to notes above about IIS & PHP reading network shares, here's one solution that works better for me.
in the management console I created a folder where my "read_dir" script runs. click on properties then select the security tab. here you can set the anonymous account to the standard IUSR_$computername% , BUT.. in this case I chose another account that I set up for reading my shares. (make sure login name and password match the credantials you set on the remote machin ;-))
I use this to read a dir and it's contents into a searchable database. and it works like a charm...`

`Thought I could help clarify something with accessing network shares on a Windows network (2000 in this case), running PHP 4.3.2 under Apache 2.0.44.
However you are logged into the Windows box, your Apache service must be running under an account which has access to the share. The easiest (and probably least safe) way for me was to change the user for the Apache service to the computer administrator (do this in the service properties, under the "Log On" tab). After restarting Apache, I could access mapped drives by their assigned drive letter ("z:\\") or regular shares by their UNC path ("\\\\shareDrive\\shareDir").`

`Re: Accessing network directories on W32
In reply to the previous comments, to enable opendir() to open directories like "\\SOMEHOST\shareddir", with PHP+IIS:
Follow the instructions here: http://support.microsoft.com/default.aspx?scid=kb;en-us;Q189408
Check that the file share allows reads to IUSR_[HOSTNAME] user.`

`I don't know if this will work the same, but I was working with copy() in order to copy a file to a network drive using IIS.
In order to be able to copy to a network drive, you have to have permissions for the user IUSR_computername where computername is the name of the computer that is running PHP. Once permissions were set up on the remote machine, PHP was able to access the remote files. I don't know if this will work the same with opendir, but it might be worth a try......`
