readdir — 从目录句柄中读取条目
$dir_handle
] )返回目录中下一个文件的文件名。文件名以在文件系统中的排序返回。
dir_handle
目录句柄的 resource ,之前由 opendir() 打开
成功则返回文件名 或者在失败时返回 FALSE
此函数可能返回布尔值
FALSE
,但也可能返回等同于 FALSE
的非布尔值。请阅读 布尔类型章节以获取更多信息。应使用
===
运算符来测试此函数的返回值。
Example #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”)。

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.

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
}
?>

[#11] Qwerp [2010-11-11 22:42:06]
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 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";

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']);
}

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
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

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);

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!
