scandir

(PHP 5)

scandir --  Получить список файлов и каталогов, расположенных по указанному пути

Описание

array scandir ( string directory [, integer sorting_order] )

Возвращает array, содержащий имена файлов и каталогов, расположенных по пути, переданном в параметре directory. Если directory не является таковым, функция возвращает логическое значение FALSE и генерирует сообщение об ошибке уровня E_WARNING.

По умолчанию, сортировка производится в алфавитном порядке по возрастанию. Если указан необязательный параметр sorting_order (равен 1), сортировка производится в алфавитном порядке по убыванию.

Пример 1. Простой пример использования функции scandir()

<?php
$dir    = '/tmp';
$files1 = scandir($dir);
$files2 = scandir($dir, 1);

print_r($files1);
print_r($files2);

/* Результатом будет нечто вроде:
Array
(
   [0] => .
   [1] => ..
   [2] => bar.php
   [3] => foo.txt
   [4] => somedir
)
Array
(
   [0] => somedir
   [1] => foo.txt
   [2] => bar.php
   [3] => ..
   [4] => .
)
*/
?>

Пример 2. Альтернативный вариант функции scandir() для PHP 4

<?php
$dir = "/tmp";
$dh  = opendir($dir);
while (false !== ($filename = readdir($dh))) {
   $files[] = $filename;
}

sort($files);

print_r($files);

rsort($files);

print_r($files);

/* Результат будет примерно таким:
Array
(
   [0] => .
   [1] => ..
   [2] => bar.php
   [3] => foo.txt
   [4] => somedir
)
Array
(
   [0] => somedir
   [1] => foo.txt
   [2] => bar.php
   [3] => ..
   [4] => .
)
*/
?>

A minor revision to elbekko at gmail dot com <PHP5 scandir function. The arsort should be rsort. Here is the complete function with the correction:

<?php
if(!function_exists('scandir')) {
   function scandir($dir, $sortorder = 0) {
       if(is_dir($dir))        {
           $dirlist = opendir($dir);
           while( ($file = readdir($dirlist)) !== false) {
               if(!is_dir($file)) {
                   $files[] = $file;
               }
           }
           ($sortorder == 0) ? asort($files) : rsort($files); // arsort was replaced with rsort
           return $files;
       } else {
       return FALSE;
       break;
       }

I would like to share a couple of functions I've made to get an Array of files of a certain extension inside a Directory.

<?php

// Firstly, a PHP 5 emulation

function php4_scandir($dir, $sort = 0)
{
   if (PHP_VERSION >= '5') return scandir($dir, $sort);
  
   $dirmap = array();
  
   if(!is_dir($dir))
   {
       trigger_error("lib::scandir($dir): failed to open dir: Invalid argument", E_USER_WARNING);
       return false;
   }
  
   $dir = opendir($dir);
  
   while (false !== ($file = readdir($dir)))
       $dirmap[] = $file;
  
   closedir($dir);
  
   ($sort == 1) ? rsort($dirmap) : sort($dirmap);
  
   return $dirmap;
}

/*
Then, this one converts directory files into array items.
It also can filter by file extension.
*/

function dir2arr($dir, $ext = null)
{
   $arr = array();
  
   if(PHP_VERSION >= '4.3.0')
   {
       # PHP 4.3.0 code
       if ($dir = glob("$dir*".(!$ext ? '.*' : '{'.$ext.', '.strtoupper($ext).'}'), GLOB_NOSORT + GLOB_BRACE))
           foreach ($dir as $file)
               $arr[] = preg_replace("#(?:.+\/{1})*([^\.]+)\.(.+)#i", '$1', $file);
   }
   else
   {
       # PHP 4.2.x code
       $dir = php4_scandir($dir); // See code snippet above
       if(!$ext) $ext = '\.[a-z]+';
       $pattern = "#([^\.|\.\.$]+)$ext#i";
       foreach ($dir as $file)
           if (preg_match($pattern, $file, $filename))
               $arr[] = $filename[1];
   }
  
   return (empty($arr) ? false : $arr);

in addition to "brodseba at brodseba dot com" from march 2005:

Perfected the script to sort files and directories
in natural alphabetic order and with files listed first.
Also added a more relative directory path approach.
And changed the javascripting for links in simple ordinary href's.

Note that the script uses scandir from the pear package
(since I'm obliged to use an older PHP version).
<?
// scandir function is for php 5.0
require_once '\pear\PHP\Compat\Function\scandir.php';
// sorting function
// based on counting of dots
function cmp($a, $b) {
if ( substr_count($a,".") ==  substr_count($b,".") ) {
if ( is_string($a) && is_string($b) ) {
return strcasecmp($a, $b) > 0 ? 1 : -1;
}elseif ( is_int($a) && is_int($b) ) {
return $a > $b ? 1 : -1;
}elseif ( is_int($a) && is_string($b) ) {
return 1;
}elseif ( is_string($a) && is_int($b) ) {
return -1;
}else {
return 0;
}}
return substr_count($a,".") <  substr_count($b,".") ? 1 : -1;
}
function ls_recursive2($dir) {
if (is_dir($dir)) {
$files = scandir($dir);
// needed to sort array
usort ($files, "cmp");
foreach ($files as $file) {
$currentfile = $dir . "/" . $file;
$last_dir = "";
// calculate the identation.
$count = substr_count($currentfile, '/');
$minus_count = substr_count($_SERVER['SCRIPT_FILENAME'], '/');
$count -= ($minus_count +1);
for($p = 0; $p < $count; $p++) {
$last_dir .= "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
}
// output with calculated identation
// first in case of directories
// run function again for directory
if (is_dir($currentfile)) {
if ($file != '.' && $file != '..') {
$sub_len = strlen(dirname($_SERVER['SCRIPT_FILENAME']))+1;
$java_targ = substr($currentfile, $sub_len);
$last_dir .= "&nbsp;&nbsp;<img src='folder.png'
alt='' align='middle' border='0'>&nbsp;
<a href=".$java_targ.">".$java_targ ."</a><br>\n";
echo $last_dir;
ls_recursive2($currentfile);
}
// if not a directory, then files in current directory
} else {
$sub_len = strlen(dirname($_SERVER['SCRIPT_FILENAME']))+1;
$java_targ = substr($currentfile, $sub_len);
$last_dir .= "<img src='file.png'
alt='' align='middle' border='0'>&nbsp;
<a href=".$java_targ.">".$java_targ."</a><br>\n";
echo $last_dir;
}}}}
?>
<?
$this = dirname($_SERVER['SCRIPT_FILENAME']);

ls_recursive2($this);

ps: I can take a comment, even some criticism,
but do understand: I'm fairly new at this.

I made a small dir listing based on file modification date, could find alot on this myself so I hope this helps someone.

<?
   $dirView="./blah";
   $dirFiles=scandir($dirView);
  
   $cwdName=array(); $cwdMod=array(); $whatWeNeed=array();
  
   // Parallel arrays (ignore the ".", ".." and inturn hidden files
   foreach ($dirFiles as $data)
   {
       if (!preg_match('/^\./', $data))
       {
           $cwdName[]=$data;
           $cwdMod[]=filemtime($dirView."/".$data);
       }
   }
  
   // Merge and sort
   $mergeArray=array_combine($cwdMod, $cwdName);
   krsort($mergeArray, SORT_NUMERIC);
  
   // Build new array
   foreach ($mergeArray as $key => $value)
   {
       $whatWeNeed[]=$value;
   }
  
   // Some maintainence
   unset($dirFiles, $cwdName, $cwdMod, $mergeArray);

   # Then can grab latest changed file/folder with whatWeNeed[0] and so on..
?>

Tested with error_reporting(E_ALL); and PHP5.1

I made a function that scans the directory and all it subfolders. You can also sort them with folders first and files after, in alphabetic order. It works with both PHP 4 and 5.

<?php

function rec_scandir($dir)
{
   $files = array();
   if ( $handle = opendir($dir) ) {
       while ( ($file = readdir($handle)) !== false ) {
           if ( $file != ".." && $file != "." ) {
               if ( is_dir($dir . "/" . $file) ) {
                   $files[$file] = rec_scandir($dir . "/" . $file);
               }else {
                   $files[] = $file;
               }
           }
       }
       closedir($handle);
       return $files;
   }
}

function cmp($a, $b)
{
   if ( is_string($a) && is_string($b) ) {
       return strcmp($a, $b) > 0 ? 1 : -1;
   }elseif ( is_int($a) && is_int($b) ) {
       return $a > $b ? 1 : -1;
   }elseif ( is_int($a) && is_string($b) ) {
       return 1;
   }elseif ( is_string($a) && is_int($b) ) {
       return -1;
   }else {
       return 0;
   }
}

function array_ukmultisort(&$arr, $func) {
   uksort($arr, $func);
   while ( list($key, $val) = each($arr) ) {
       if ( is_array($val) ) {
           array_ukmultisort($arr[$key], $func);
       }
   }
}

$dir = rec_scandir(".");
array_ukmultisort($dir, "cmp");
echo "<pre>";
print_r($dir);
echo "</pre>";

Here is a little script that i through together to count the files in my directory while excluding the "."  i hope it helps you out!

<?
$dir = ".";
$sort = 0;
   $dir_open = @ opendir($dir);
 
   while (($dir_content = readdir($dir_open)) !== false)
           $files[] = $dir_content;
 
   if ($sort == 1) {
       rsort($files, SORT_STRING);
} else {
       sort($files, SORT_STRING);
}
$a=0;
$b=10;
$file_s="";
while($a < $b) {
 
$c=1;
$d=5;

while($c < $d) {
$dot[$c.",".$a]=str_repeat(".", $c);
if($files[$a] == $dot[$c.",".$a]) {
unset($files[$a]);
} else {

}

$c++;

}

if($files[$a] != "") {
$brake[$a]="<br>";
} else {
$brake[$a]="";
}

$file_s.=$files[$a].$brake[$a];

$a++;

}
echo $file_s;

echo "<br><br><br>";

echo count($files);

For non php5-users here you are this function...
It isn't set the wrapper, but I think it's enough :P.

If no pararameter is set, the scandir() function will scan the local file directory.

Set the optional parameter "$sort" to 1 to reverse the alphabetical-sorting.

<?
function scandir($dir = './', $sort = 0)
{
  
   $dir_open = @ opendir($dir);
  
   if (! $dir_open)
       return false;
      
      
   while (($dir_content = readdir($dir_open)) !== false)
           $files[] = $dir_content;
  
   if ($sort == 1)
       rsort($files, SORT_STRING);
   else
       sort($files, SORT_STRING);
  
   return $files;
}

I made this to represent a directory tree in an array that uses the file or directory names as keys and full paths as the value for files. Directories are nested arrays.

<?php
function generatePathTree($rootPath) {
   $pathStack = array($rootPath);
   $contentsRoot = array();
   $contents = &$contentsRoot;
   while ($path = array_pop($pathStack)) {
       $contents[basename($path)] = array();
       $contents = &$contents[basename($path)];
       foreach (scandir($path) as $filename) {
           if ('.' != substr($filename, 0, 1)) {
               $newPath = $path.'/'.$filename;
               if (is_dir($newPath)) {
                   array_push($pathStack, $newPath);
                   $contents[basename($newPath)] = array();
               } else {
                   $contents[basename($filename)] = $newPath;
               }
           }
       }
   }
   return $contentsRoot[basename($rootPath)];
}
?>

The function will return something like this:

Array
(
   [index.php] => /usr/local/www/index.php
   [js] => Array
       (
           [async.js] => /usr/local/www/js/async.js
           [dom.js] => /usr/local/www/js/dom.js
           [effects.js] => /usr/local/www/js/effects.js
           [prototype.js] => /usr/local/www/js/prototype.js
       )

   [logo.png] => /usr/local/www/logo.png
   [server.php] => /usr/local/www/server.php
   [test.js] => /usr/local/www/test.js
)

Im wanting to when php executed for the script to scan for certain file extensions in a windows mapped out folder which is set as H:\ when a user logs on.

Will the php scan locally (the linux box) or will it work client side like i want?

i was triyng to do something similar to the ls -R command in linux, so, using the functions from csaba , i could, so, using this simple lines, you'll get that result:

<?php

$directory = "."; // for the actual directory
$directories = dirList($directory, 2, 0); // this calls the csaba's function dirlist, wich has type 2(files) and level 0($path and all subdirectories) as parameters. And it will return an array with all the returned paths

//so i cross all over the array doing an echo for every single item of the array
foreach ($directories as $dir){
   echo $dir."<br>";
}

?>

and that's it, remember that you need the functions listed above from csaba to use this

For directory containing files like (for example) -.jpg the results of scandir are a little "weird" ;)

<?php
  
   $dir = '/somedir';
   $files = scandir($dir);
   print_r($files);
?>

Array
(
   [0] => -.jpg
   [1] => .
   [2] => ..
   [3] => foo.txt
   [4] => somedir
)

Beware - sorting is in ASCII order :)

using sort of scandir() that returns the content sorted by Filemodificationtime.

<?php
function scandir_by_mtime($folder) {
  $dircontent = scandir($folder);
  $arr = array();
  foreach($dircontent as $filename) {
   if ($filename != '.' && $filename != '..') {
     if (filemtime($folder.$filename) === false) return false;
     $dat = date("YmdHis", filemtime($folder.$filename));
     $arr[$dat] = $filename;
   }
  }
  if (!ksort($arr)) return false;
  return $arr;
}
?>

returns false if an error occured
otherwise it returns an array like this.
Array
(
   [20040813231320] => DSC00023.JPG
   [20040813231456] => DSC00024.JPG

This function create a HTML view of a directory.  It also look for subdirectory.  I use some icon to differ from folders or files.  It's also possible to get specific icon for specific file type.

Each entrey is clickable so you can use it to populate a form field.

Have fun!

Scandir on steroids:
For when you want to filter your file list, or only want to list so many levels of subdirectories...

<?php
function dirList($path="", $types=2, $levels=1, $aFilter=array()) {
//  returns an array of the specified files/directories
//  start search in $path (defaults to current working directory)
//  return $types:  2 => files; 1 => directories; 3 => both;
//  $levels: 1 => look in the $path only; 2 => $path and all children;
//          3 => $path, children, grandchildren; 0 => $path and all subdirectories;
//          less than 0 => complement of -$levels, OR everything starting -$levels down
//                e.g. -1 => everthing except $path; -2 => all descendants except $path + children
//  Remaining argument(s) is(are) a filter array(list) of regular expressions which operate on the full path.
//    First character (before the '/' of the regExp) '-' => NOT.
//    First character (after a possible '-') 'd' => apply to directory name
//    The filters may be passed in as an array of strings or as a list of strings
//  Note that output directories are prefixed with a '*' (done in the line above the return)
   $dS = DIRECTORY_SEPARATOR;
   if (!($path = realpath($path?$path:getcwd()))) return array();    // bad path
   // next line rids terminating \ on drives (works since c: == c:\ on PHP).  OK in *nix?
   if (substr($path,-1)==$dS) $path = substr($path,0,-1);
   if (is_null($types)) $types = 2;
   if (is_null($levels)) $levels = 1;
   if (is_null($aFilter)) $aFilter=array();

   // last argument may be passed as a list or as an array
   $aFilter = array_slice(func_get_args(),3);
   if ($aFilter && gettype($aFilter[0])=="array") $aFilter=$aFilter[0];
   $adFilter = array();
   // now move directory filters to separate array:
   foreach ($aFilter as $i=>$filter)                  // for each directory filter...
     if (($pos=stripos(" $filter","d")) && $pos<3) {  // next line eliminates the 'd'
         $adFilter[] = substr($filter,0,$pos-1) . substr($filter,$pos);
         unset($aFilter[$i]); }
   $aFilter = array_merge($aFilter);    // reset indeces

   $aRes = array();                    // results, $aAcc is an Accumulator
   $aDir = array($path);    // dirs to check
   for ($i=$levels>0?$levels++:-1;($aAcc=array())||$i--&&$aDir;$aDir=$aAcc)
     while ($dir = array_shift($aDir))
         foreach (scandir ($dir) as $fileOrDir)

               if ($dirP = is_dir ($rp="$dir$dS$fileOrDir"))

example usage:
<?php
define ("_", NULL);

$aFiles = dirList('c:\Photo', _, 0, '-/\.jpg$/i', '-/\\\\Thumbs.db$/');
$aFiles = dirList();    // find the files in the current directory
// next lines will find .jpg files in non Photo(s) subdirectories, excluding Temporary Internet Files
set_time_limit(60);        // iterating from the top level can take a while
$aFiles = dirList("c:\\", _, 0, '/\.jpg$/i', '-d/\\\\Photos?$/i', '-d/Temporary Internet/i');
?>

See my earlier entry for the definition of pathFilter(...)
Note that this function will consume a lot of time if scanning large
directory structures (which is the reason for the '[-]d/.../' filters).

A nice way to filter the files/directories you get back from scandir:

<?php
function pathFilter ($path, $aFilter) {
   // returns true iff $path survives the tests from $aFilter
   // $aFilter is an array of regular expressions: [-]/regExp/modifiers
   // if there is a leading '-' it means exclude $path upon a match (a NOT test)
   // If the first expression has a leading '-', $path is in, unless it gets excluded.
   // Otherwise, $path is out, unless it gets included via the filter tests.
   // The tests are applied in succession.
   // A NOT test is applied only if $path is currently (within the tests) included
   // Other tests are applied only if $path is currently excluded.  Thus,
   // array("/a/", "-/b/", "/c/") => passes if $path has a c or if $path has an a but no b
   // array("/a/", "/c/", "-/b/") => passes if $path has an a or c, but no b
   // array("-/b/", "/a/", "/c/") => passes if $path has no b, or if $path has an a or c
   if (!$aFilter) return true;          // automatic inclusion (pass) if no filters
   foreach ($aFilter as $filter) break;  // we don't know how it's indexed
   $in = $filter[0]=="-";                // initial in/exclusion based on first filter
   foreach ($aFilter as $filter)        // walk the filters
     if ($in==$not=($filter[0]=="-"))  //    testing only when necessary
         $in ^= preg_match(substr($filter,$not),$path);    // flip in/exclusion upon a match
   return $in;
}
?>

Ok, in my previous example, you need to do the SORT after you remove the "." and ".." entries from the array.  Otherwise, you cannot start using the array at 0.

Here is corrected code:

<?php

function scandir($dir, $no_dots=FALSE) {

   $files = array();
   $dh  = @opendir($dir);
   if ($dh!=FALSE) {
       while (false !== ($filename = readdir($dh))) {
           $files[] = $filename;
       }

       if ($no_dots) {
           while(($ix = array_search('.',$files)) > -1)
                   unset($files[$ix]);
           while(($ix = array_search('..',$files)) > -1)
                   unset($files[$ix]);
       }

       sort($files);

   }
   return $files;
}

?>

Since I needed to scan dirs and subdirs and wanted to have files and dirs not in the same var without having to explode it, I did this little function:

<?php

function scan_Dir($directory=NULL)
{
$temp = "";
if ($directory==NULL)
{
       $directory = getcwd();
}
$handle = opendir($directory);
while (false !== ($filename = readdir($handle)))
{
       if (($filename!=".") AND ($filename!=".."))
       {
               if (is_dir($directory."/".$filename))
               {
                       $old_directory = $directory;
                       $directory .= "/".$filename;
                       $temp = scan_Dir($directory);

                       $cpt = 0;
                       while ($cpt<count($temp["filename"]))
                       {
                               $arrfiles["path"][]      = $directory."/".$temp["filename"][$cpt];
                               $arrfiles["directory"][] = $directory;
                               $arrfiles["filename"][]  = $temp["filename"][$cpt];
                               $cpt++;
                       }
                       $directory = $old_directory;
               }
               else
               {
                       $arrfiles["path"][]      = $directory."/".$filename;
                       $arrfiles["directory"][] = $directory;
                       $arrfiles["filename"][]  = $filename;
               }
       }
}
return $arrfiles;
}
?>

This one seems to work properly and use multidimensional array.

To show your files, just use:
<?php

$dir2scan = "admin";
$yourvar = scan_Dir($dir2scan);

echo $yourvar["path"][0]."<br>"; //Complete path of the file with key 0 (dir + filename)

echo $yourvar["directory"][0]."<br>"; //Directory of the file with key 0

echo $yourvar["filename"][0]."<br>"; //Filename of the file with key 0

?>

Note that the parameter of the function is not necessary. If you don't give any, it will scan from the returned value of getcwd() function.

Scandir can be used to make directories of files not unlike apache's indexes, but CSS enabled and fully customizable:

<?
//in this example, we'll say the directory is "images"
$list = scandir("images");
$i = 0;
$num = count($list);
while($i < $num){
print "<a href=\"images/$list[$i]\">$list[$i]</a><br />";
$i++;
}
?>

That will print all the files in the "images" directory linked to the files.

scandir() with regexp matching on file name and sorting options based on stat().

function myscandir($dir, $exp, $how='name', $desc=0)
{
   $r = array();
   $dh = @opendir($dir);
   if ($dh) {
       while (($fname = readdir($dh)) !== false) {
           if (preg_match($exp, $fname)) {
               $stat = stat("$dir/$fname");
               $r[$fname] = ($how == 'name')? $fname: $stat[$how];
           }
       }
       closedir($dh);
       if ($desc) {
           arsort($r);
       }
       else {
           asort($r);
       }
   }
   return(array_keys($r));
}

$r = myscandir('./book/', '/^article[0-9]{4}\.txt$/i', 'ctime', 1);
print_r($r);

files can be sorted on name and stat() attributes, ascending and descending:

name    file name
dev    device number
ino    inode number
mode    inode protection mode
nlink  number of links
uid    userid of owner
gid    groupid of owner
rdev    device type, if inode device *
size    size in bytes
atime  time of last access (Unix timestamp)
mtime  time of last modification (Unix timestamp)
ctime  time of last inode change (Unix timestamp)
blksize blocksize of filesystem IO *
blocks  number of blocks allocated
