opendir
说明
resource opendir ( string path [, resource context] )打开一个目录句柄，可用于之后的 closedir()，readdir() 和 rewinddir() 调用中。
返回值
如果成功则返回目录句柄的 resource，失败则返回 FALSE。
如果 path
不是一个合法的目录或者因为权限限制或文件系统错误而不能打开目录，opendir()
返回 FALSE 并产生一个 E_WARNING
级别的 PHP 错误信息。可以在 opendir()
前面加上“@”符号来抑制错误信息的输出。

In reponse to Tozeiler. Nice short directory dump. However, that displays the "." and "..". This removes those. It also makes an ordered list in case I needed to be on the phone while looking at the page. Easy to call out.
<?php
$path = "your path";
$dh = opendir($path);
$i=1;
while (($file = readdir($dh)) !== false) {
if($file != "." && $file != "..") {
echo "$i. <a href='$path/$file'>$file</a><br />";
$i++;
}
}
closedir($dh);

Using Apache 2.2.4 with PHP and MySQL I was trying to connect to a Novell Netware drive using opendir("R:/") where R: was pointing to a Netware resource on another server. The error returned was
Warning: opendir(R:/) [function.opendir]: failed to open dir: No such file or directory in path/to/my/phpfile/containing/opendir on line 34.
Basically it is a problem with Netware rights and users and how the apache service was trying to connect to the resource.
To get everything working as expected in the end we set up a Windows user account eg: webhost with the same password as a Netware account with username webhost, set the Netware account to have rights to the resource R:/ (we just used admin rights), and set the apache service to run as the webhost user using the username password combo.
Hope this helps someone else out.

Here's a function that will recrusively turn a directory into a hash of directory hashes and file arrays, automatically ignoring "dot" files.
<?php
function hashify_directory($topdir, &$list, $ignoredDirectories=array()) {
if (is_dir($topdir)) {
if ($dh = opendir($topdir)) {
while (($file = readdir($dh)) !== false) {
if (!(array_search($file,$ignoredDirectories) > -1) && preg_match('/^\./', $file) == 0) {
if (is_dir("$topdir$file")) {
if(!isset($list[$file])) {
$list[$file] = array();
}
ksort($list);
hashify_directory("$topdir$file/", $list[$file]);
} else {
array_push($list, $file);
}
}
}
closedir($dh);
}
}
}
?>
e.g.
<?php
$public_html["StudentFiles"] = array();
hashify_directory("StudentFiles/", $public_html["StudentFiles"]);
?>
on the directory structure:
./StudentFiles/tutorial_01/case1/file1.html
./StudentFiles/tutorial_01/case1/file2.html
./StudentFiles/tutorial_02/case1/file1.html
./StudentFiles/tutorial_02/case2/file2.html
./StudentFiles/tutorial_03/case1/file2.html
etc...
becomes:
<?php
print_r($public_html);
/*
outputs:
array(
"StudentFiles" => array (
"tutorial_01" => array (
"case1" => array( "file1.html", "file2.html")
),
"tutorial_02" => array (
"case1" => array( "file1.html"),
"case2" => array( "file2.html")
),
"tutorial_03" => array (
"case1" => array( "file2.html")
)
)
)
*/

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!

In my previous post I ran into a problem with the "global" definition of $directorylist. If I called the function more than once on the same page it would combine the file lists. I looked at Lasse Dalegaard's example and used the following solution.
remove global definition
global $directorylist;
REPLACE
<?
if ((($maxlevel) == "all") or ($maxlevel > $level)) {
filelist($startdir . $file . "/", $searchSubdirs, $directoriesonly, $maxlevel, $level + 1);
}
?>
WITH
<?
if ((($maxlevel) == "all") or ($maxlevel > $level)) {
$list2 = filelist($startdir . $file . "/", $searchSubdirs, $directoriesonly, $maxlevel, $level + 1);
if(is_array($list2)) {
$directorylist = array_merge($directorylist, $list2);

recursive_delete($dir);
function recursive_delete( $dir )

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

I made a function for finding all files in a specified directory and all subdirectories. It can be quite usefull when searching in alot of files in alot subdirectories. The function returns an array with the path of all the files found.
<?

// Try to open the directory
if($dir = opendir($directory)) {
// Create an array for all files found
$tmp = Array();
// Add the files
while($file = readdir($dir)) {
// Make sure the file exists
if($file != "." && $file != ".." && $file[0] != '.') {
// If it's a directiry, list all files within it
if(is_dir($directory . "/" . $file)) {
$tmp2 = getFiles($directory . "/" . $file);
if(is_array($tmp2)) {
$tmp = array_merge($tmp, $tmp2);
}
} else {
array_push($tmp, $directory . "/" . $file);
}
}
}
// Finish off the function
closedir($dir);
return $tmp;
}
}
// Example of use
print_r(getFiles('.')); // This will find all files in the current directory and all subdirectories

This is a little script i wrote to generate a home page on my dev box by parsing the contents of my htdocs directory. It is encapsulated in a html table
Arb but useful if you are as lazy as I am ;)
<?
$handle = opendir("./");
while (($file = readdir($handle))!==false) {
if(is_dir($file)){
if($file != "." && $file != ".."){?>
<tr>
<td align="center" bgcolor="FFFFFF"><a href="<?= $file;?>"><?php echo ucwords($file)?></a></strong></td>
</tr>
<?php
}
}
}
closedir($handle);
$handle = opendir("./");
while (($file = readdir($handle))!==false) {
if(is_file($file)){
if($file != "." && $file != ".."){?>
<tr>
<td align="center" bgcolor="FFFFFF"><a href="<?= $file?>"><?php echo ucwords($file)?></a></strong></td>
</tr>
<?php
}
}
}
closedir($handle);

Here is a snippet of the code that I created to search for a file..recursively open the directories and search for a match..
<?
function search($target, $directory){
if(is_dir($directory)){
$direc = opendir($directory);
while(false !== ($file = readdir($direc))){
if($file !="." && $file != ".."){
if(is_file($directory."/".$file)){
if(preg_match("/$target/i", $file)){
echo "<a href=\"$directory/$file\">$file</a><br>";
}
}else if(is_dir($directory."/".$file)){
search($target,$directory."/".$file);
}
}
}
closedir($direc);
}
return ;
}
?>

Here's another version of directory listing, since I had some problems using the examples below. It will display the content of the current directory, sorted by directories and files.
You can also search subdirectories by setting $maxDepth > 0. There's a link to other directories, so you can easily switch to the parent directory or to other directories in the current directory.
Hope it helps!
<?php
// show directory content
function showDir($dir, $i, $maxDepth){
$i++;
if($checkDir = opendir($dir)){
$cDir = 0;
$cFile = 0;
// check all files in $dir, add to array listDir or listFile
while($file = readdir($checkDir)){
if($file != "." && $file != ".."){
if(is_dir($dir . "/" . $file)){
$listDir[$cDir] = $file;
$cDir++;
}
else{
$listFile[$cFile] = $file;
$cFile++;
}
}
}
// show directories
if(count($listDir) > 0){
sort($listDir);
for($j = 0; $j < count($listDir); $j++){
echo "
<tr>";
$spacer = "";
for($l = 0; $l < $i; $l++) $spacer .= " ";
// create link
$link = "<a href=\"" . $_SERVER["PHP_SELF"] . "?dir=" . $dir . "/" . $listDir[$j] . "\">$listDir[$j]</a>";
echo "<td>" . $spacer . $link . "</td>
</tr>";
// list all subdirectories up to maxDepth
if($i < $maxDepth) showDir($dir . "/" . $listDir[$j], $i, $maxDepth);
}
}
// show files
if(count($listFile) > 0){
sort($listFile);
for($k = 0; $k < count($listFile); $k++){
$spacer = "";
for($l = 0; $l < $i; $l++) $spacer .= " ";
echo "
<tr>
<td>" . $spacer . $listFile[$k] . "</td>
</tr>";
}
}
closedir($checkDir);
}
}
if($_GET["dir"] == "" || !is_dir($_GET["dir"])) $dir = getcwd();
else $dir = $_GET["dir"];
// replace backslashes, not necessary, but better to look at
$dir = str_replace("\\", "/", $dir);
// show parent path
$pDir = pathinfo($dir);
$parentDir
