Since I feel this is rather vague and non-helpful, I thought I'd make a post detailing the mechanics of the glob regex.
glob uses two special symbols that act like sort of a blend between a meta-character and a quantifier. These two characters are the * and ?
The ? matches 1 of any character except a /
The * matches 0 or more of any character except a /
If it helps, think of the * as the pcre equivalent of .* and ? as the pcre equivalent of the dot (.)
Note: * and ? function independently from the previous character. For instance, if you do glob("a*.php") on the following list of files, all of the files starting with an 'a' will be returned, but * itself would match:
a.php // * matches nothing
aa.php // * matches the second 'a'
ab.php // * matches 'b'
abc.php // * matches 'bc'
b.php // * matches nothing, because the starting 'a' fails
bc.php // * matches nothing, because the starting 'a' fails
bcd.php // * matches nothing, because the starting 'a' fails
It does not match just a.php and aa.php as a 'normal' regex would, because it matches 0 or more of any character, not the character/class/group before it.
Executing glob("a?.php") on the same list of files will only return aa.php and ab.php because as mentioned, the ? is the equivalent of pcre's dot, and is NOT the same as pcre's ?, which would match 0 or 1 of the previous character.
glob's regex also supports character classes and negative character classes, using the syntax [] and [^]. It will match any one character inside [] or match any one character that is not in [^].
With the same list above, executing
glob("[ab]*.php) will return (all of them):
a.php // [ab] matches 'a', * matches nothing
aa.php // [ab] matches 'a', * matches 2nd 'a'
ab.php // [ab] matches 'a', * matches 'b'
abc.php // [ab] matches 'a', * matches 'bc'
b.php // [ab] matches 'b', * matches nothing
bc.php // [ab] matches 'b', * matches 'c'
bcd.php // [ab] matches 'b', * matches 'cd'
glob("[ab].php") will return a.php and b.php
glob("[^a]*.php") will return:
b.php // [^a] matches 'b', * matches nothing
bc.php // [^a] matches 'b', * matches 'c'
bcd.php // [^a] matches 'b', * matches 'cd'
glob("[^ab]*.php") will return nothing because the character class will fail to match on the first character.
You can also use ranges of characters inside the character class by having a starting and ending character with a hyphen in between. For example, [a-z] will match any letter between a and z, [0-9] will match any (one) number, etc..
glob also supports limited alternation with {n1, n2, etc..}. You have to specify GLOB_BRACE as the 2nd argument for glob in order for it to work. So for example, if you executed glob("{a,b,c}.php", GLOB_BRACE) on the following list of files:
a.php
b.php
c.php
all 3 of them would return. Note: using alternation with single characters like that is the same thing as just doing glob("[abc].php"). A more interesting example would be glob("te{xt,nse}.php", GLOB_BRACE) on:
tent.php
text.php
test.php
tense.php
text.php and tense.php would be returned from that glob.
glob's regex does not offer any kind of quantification of a specified character or character class or alternation. For instance, if you have the following files:
a.php
aa.php
aaa.php
ab.php
abc.php
b.php
bc.php
with pcre regex you can do ~^a+\.php$~ to return
a.php
aa.php
aaa.php
This is not possible with glob. If you are trying to do something like this, you can first narrow it down with glob, and then get exact matches with a full flavored regex engine. For example, if you wanted all of the php files in the previous list that only have one or more 'a' in it, you can do this:
<?php
$list = glob("a*.php");
foreach ($list as $l) {
if (preg_match("~^a+\.php$~",$file))
$files[] = $l;
}
?>
glob also does not support lookbehinds, lookaheads, atomic groupings, capturing, or any of the 'higher level' regex functions.
glob does not support 'shortkey' meta-characters like \w or \d.

Those of you with PHP 5 don't have to come up with these wild functions to scan a directory recursively: the SPL can do it.
<?php
$dir_iterator = new RecursiveDirectoryIterator("/path");
$iterator = new RecursiveIteratorIterator($dir_iterator, RecursiveIteratorIterator::SELF_FIRST);
// could use CHILD_FIRST if you so wish
foreach ($iterator as $file) {
echo $file, "\n";
}
?>
Not to mention the fact that $file will be an SplFileInfo class, so you can do powerful stuff really easily:
<?php
$size = 0;
foreach ($iterator as $file) {
if ($file->isFile()) {
echo substr($file->getPathname(), 27) . ": " . $file->getSize() . " B; modified " . date("Y-m-d", $file->getMTime()) . "\n";
$size += $file->getSize();
}
}
echo "\nTotal file size: ", $size, " bytes\n";
?>

Please note that glob('*') ignores all 'hidden' files by default. This means it does not return files that start with a dot (e.g. ".file").
If you want to match those files too, you can use "{,.}*" as the pattern with the GLOB_BRACE flag.
<?php
// Search for all files that match .* or *
$files = glob('{,.}*', GLOB_BRACE);
?>
Note: This also returns the directory special entries . and ..

Note that in case you are using braces with glob you might retrieve duplicated entries for files that matche more than one item :
<?php
$a = glob('/path/*{foo,bar}.dat',GLOB_BRACE);
print_r($a);
?>
Result :
Array
(
[0] => /path/file_foo.dat
[1] => /path/file_foobar.dat
[2] => /path/file_foobar.dat
)

glob() isn't limited to one directory:
<?php
$results=glob("{includes/*.php,core/*.php}",GLOB_BRACE);
echo '<pre>',print_r($results,true),'</pre>';
?>
Just be careful when using GLOB_BRACE regarding spaces around the comma:
{includes/*.php,core/*.php} works as expected, but
{includes/*.php, core/*.php} with a leading space, will only match the former as expected but not the latter
unless you have a directory named " core" on your machine with a leading space.
PHP can create such directories quite easily like so:
mkdir(" core");

glob is case sensitive, even on Windows systems.
It does support character classes though, so a case insensitive version of
<?php glob('my/dir/*.csv') ?>
could be written as
<?php glob('my/dir/*.[cC][sS][vV]') ?>

glob() (array_sum() and array_map() in fact too) can be very useful if you want to calculate the sum of all the files' sizes located in a directory:
<?php
$bytes = array_sum(array_map('filesize',glob('*')));
?>
Unfortunately there's no way to do this recursively, using glob() (as far as I know).
david dot schueler at tel-billig dot de ¶

Don't use glob() if you try to list files in a directory where very much files are stored (>100.000). You get an "Allowed memory size of XYZ bytes exhausted ..." error.
You may try to increase the memory_limit variable in php.ini. Mine has 128MB set and the script will still reach this limit while glob()ing over 500.000 files.
The more stable way is to use readdir() on very large numbers of files:
<?php
// code snippet
if ($handle = opendir($path)) {
while (false !== ($file = readdir($handle))) {
// do something with the file
// note that '.' and '..' is returned even
}
closedir($handle);
}
?>

This is a simple and versatile function that returns an array tree of files, matching wildcards:
<?php
// List files in tree, matching wildcards * and ?
function tree($path){
static $match;
// Find the real directory part of the path, and set the match parameter
$last=strrpos($path,"/");
if(!is_dir($path)){
$match=substr($path,$last);
while(!is_dir($path=substr($path,0,$last)) && $last!==false)
$last=strrpos($path,"/",-1);
}
if(empty($match)) $match="/*";
if(!$path=realpath($path)) return;
// List files
foreach(glob($path.$match) as $file){
$list[]=substr($file,strrpos($file,"/")+1);
}
// Process sub directories
foreach(glob("$path/*", GLOB_ONLYDIR) as $dir){
$list[substr($dir,strrpos($dir,"/",-1)+1)]=tree($dir);
}
return @$list;
}
?>

First off, it's nice to see all of the different takes on this. Thanks for all of the great examples.
Fascinated by the foreach usage I was curious how it might work with a for loop. I found that glob was well suited for this, especially compared to opendir. The for loop is always efficient when you want to protect against a potential endless loop.
$dir=$_SERVER['DOCUMENT_ROOT']."/test/directory_listing/test";
echo $dir;
$filesArray=glob($dir."/*.*");
$line.="<pre>";
$line.=print_r($filesArray, true);
$line.="</pre>";
$line.="<hr>";
for($i=0;$i<count($filesArray);$i++) {
$line.=key($filesArray)." - ";
$line.=$filesArray[$i]."<br/>";
next($filesArray);
}
echo $line;
Note that I pulled the glob array keys if you should need them.
Also you can tweak it for searches with something like this... (case sensitive)
$search_names="Somedocname";
$filesArray=glob($dir."/".$search_names."*.*");
Enjoy!

You can use multiple asterisks with the glob() - function.
Example:
<?php
$paths = glob('my/*/dir/*.php');
?>
$paths will contains paths as following examples:
- my/1/dir/xyz.php
- my/bar/dir/bar.php
- my/bar/dir/foo.php

I lost hours looking for the solution for this problem.
glob() wasn't eating up my directory names (stuff like "foobar[]"), and I searched online for some hours, I tried preg_quote to no avail.
I finally found the proper way to escape stuff in glob() in an obscure Python mailing list:
<?php
preg_replace('/(\*|\?|\[)/', '[$1]', $dir_path);
?>
If you want to add a directory path before your pattern, you should do it like this:
<?php
glob(preg_replace('/(\*|\?|\[)/', '[$1]', $dir_path).'*.txt');
?>
preg_quote WILL NOT work in all cases (if any).

As a follow up to recursively determining all paths (by viajy at yoyo dot org) and opendir being faster than glob (by Sam Yong - hellclanner at live [dot] com).
The list all dirs code didn't seem to work, at least on my server (provided by parazuce [at] gmail [dot] com).
I needed a function to create an unlimited multidimensional array, with the names of the folders/files intact (no realpath's, although that is easily possible). This is so I can simply loop through the array, create an expandable link on the folder name, with all the files inside it.
This is the correct way to recurse I believe (no static, return small arrays to build up the multidimensional array), and includes a check for files/folders beginning with dots.
// may need modifications
function list_files($path)
{
$files = array();
if(is_dir($path))
{
if($handle = opendir($path))
{
while(($name = readdir($handle)) !== false)
{
if(!preg_match("#^\.#", $name))
if(is_dir($path . "/" . $name))
{
$files[$name] = list_files($path . "/" . $name);
}
else
{
$files[] = $name;
}
}
closedir($handle);
}
}
return $files;
}
print_r(list_files("/path/to/folder"));
// example usage
function list_html($list)
{
$html = "";
foreach($list as $folder => $file)
{

{
$html .= "> (folder) " . $folder . "<br>";
$html .= list_html($list[$folder]);

If you want to use wildcard expressions (like they are used by glob() ) to search on strings, you can use this function:
<?php
function match_wildcard( $wildcard_pattern, $haystack ) {
$regex = str_replace(
array("\*", "\?"), // wildcard chars
array('.*','.'), // regexp chars
preg_quote($wildcard_pattern)
);
return preg_match('/^'.$regex.'$/is', $haystack);
}
$test = "foobar and blob\netc.";
var_dump(
match_wildcard('foo*', $test), // TRUE
match_wildcard('bar*', $test), // FALSE
match_wildcard('*bar*', $test), // TRUE
match_wildcard('**blob**', $test), // TRUE
match_wildcard('*a?d*', $test), // TRUE
match_wildcard('*etc**', $test) // TRUE
);

In some systems (AIX for example) GLOB_BRACE isn't defined and you get the error:
glob() expects parameter 2 to be long, string given in /XX/XX.php
<?
foreach (glob("{*.pdf,*.PDF}",GLOB_BRACE ) as $filename) {
echo "$filename \n";
}
?>
The method may help you in this case.
<?
foreach (array_merge(glob("*.pdf"),glob("*.PDF")) as $filename) {
echo "$filename \n";
}

To pick one of the file randomly from your directory with full physical path, you can write something like this:
<?php
function one_random_image_file()
{
$files = glob('../images/*.jpg');
shuffle($files);
return realpath($files[0]);
}
$image_to_read = one_random_image_file();

You can do a recursive file search with yield.

$dirStack=[$start];
while($dir=array_shift($dirStack)) {
$ar=glob($dir.'/*',GLOB_ONLYDIR|GLOB_NOSORT);
if(!$ar) continue;

foreach($ar as $DIR)
yield $DIR;
}

$fname='*.php';
$result=[];
foreach(findAllDirs('/var/www/localhost') as $dir) {
$match=glob($dir.'/'.$fname,GLOB_NOSORT);
if(!$match) continue;
$result=array_merge($result,$match);
}
print_r($result);

As a response to a post by viajy at yoyo dot org on 10-Feb-2007 04:50, he posted the following code:
<?php
function listdirs($dir) {
static $alldirs = array();
$dirs = glob($dir . '/*', GLOB_ONLYDIR);
if (count($dirs) > 0) {
foreach ($dirs as $d) $alldirs[] = $d;
}
foreach ($dirs as $dir) listdirs($dir);
return $alldirs;
}
?>
It is not best practice to use recursive functions like that, so I wrote a safe (non-recursive) function below:
<?php
function listdirs_safe($start)
{
$dir = $start;
$dirs = array();
$next = 0;
while (true)
{
$_dirs = glob($dir.'/*', GLOB_ONLYDIR);
if (count($_dirs) > 0)
{
foreach ($_dirs as $key => $_dir)
$dirs[] = $_dir;
}
else
break;
$dir = $dirs[$next++];
}
return $dirs;
}
?>
Example:
print_r(listdirs_safe('*'));
Output:
Array
(
[0] => Dummy folder/Dummy folder 2
[1] => Dummy folder/Dummy folder 2/Dummy Folder 3
[2] => Dummy folder/Dummy folder 2/Dummy Folder 3/4
[3] => Dummy folder/Dummy folder 2/Dummy Folder 3/Dummy folder 4
[4] => Dummy folder/Dummy folder 2/Dummy Folder 3/4/5

The example on this page will generate a warning if the glob function does not find any filenames that match the pattern.
The glob function result will only be an array if it finds some files and the foreach statement requires its argument to be an array.
By checking for the possibility that the result of the glob function may not be an array you can eliminate the warning.
Here's a better example:
<?php
$matches = glob("*.txt");
if ( is_array ( $matches ) ) {
foreach ( $matches as $filename) {
echo "$filename size " . filesize($filename) . "\n";
}
}
?>

If you have open_basedir set in php.ini to limit which files php can execute, glob(...) will return false when there are no matching files. If open_basedir is not set, the very same code will return an empty array in the same situation.
This is unfortunate as a seemingly innocuous change causes different functionality that breaks code like:
foreach(glob("*.ext") as $file)
...
See this link if you have any questions as to why this is so:

For those who need to recursively search a directory tree and cannot or wish not to call a function within itself here is another suggestion.
I tried the previously suggested listdirs_safe() and it didn't seem to find all subfolders in a directory tree.
There are two variations on the same theme.
Single Array.
<?php
$dir ='/dir';
while($dirs = glob($dir . '/*', GLOB_ONLYDIR)) {
$dir .= '/*';
if(!$d) {
$d=$dirs;
} else {
$d=array_merge($d,$dirs);
}
}
?>
Multiple arrays.
<?php
$n=0;
$dir ='/dir';
while($dirs = glob($dir . '/*', GLOB_ONLYDIR)) {
$dir .= '/*';
if(!$d) {
$d=$dirs;
} else {
$d[$n]=$dirs;
}
$n++;
}
?>
This will result in the glob looping via "dir/*/*/*/*.." until it is no longer finding a directory structure.

Here is a function that returns specific files in an array, with all of the details. Includes some basic garbage checking.
Variables
$source_folder // the location of your files
$ext // file extension you want to limit to (i.e.: *.txt)
$sec // if you only want files that are at least so old.
The function
function glob_files($source_folder, $ext, $sec, $limit){
if( !is_dir( $source_folder ) ) {
die ( "Invalid directory.\n\n" );
}
$FILES = glob($source_folder."\*.".$ext);
$set_limit = 0;
foreach($FILES as $key => $file) {
if( $set_limit == $limit ) break;
if( filemtime( $file ) > $sec ){
$FILE_LIST[$key]['path'] = substr( $file, 0, ( strrpos( $file, "\\" ) +1 ) );
$FILE_LIST[$key]['name'] = substr( $file, ( strrpos( $file, "\\" ) +1 ) );
$FILE_LIST[$key]['size'] = filesize( $file );
$FILE_LIST[$key]['date'] = date('Y-m-d G:i:s', filemtime( $file ) );
$set_limit++;
}
}
if(!empty($FILE_LIST)){
return $FILE_LIST;
} else {
die( "No files found!\n\n" );
}
}
So....
$source_folder = "c:\temp\my_videos";
$ext = "flv"; // flash video files
$sec = "7200"; // files older than 2 hours
$limit = 2;
print_r(glob_files($source_folder, $ext, $sec, $limit));
Would return:
Array
(
[0] => Array
(
[path] => c:\temp\my_videos\
[name] => fluffy_bunnies.flv
[size] => 21160480
[date] => 2007-10-30 16:48:05
)
[1] => Array
(
[path] => c:\temp\my_videos\
[name] => synergymx.com.flv
[size] => 14522744
[date] => 2007-10-25 15:34:45
)

Use this to exclude hidden files on MS Windows.
<?php
exec("dir \"{$path}\" /A:-H /B", $result);

Here is the function array_prepend() used by my latest post of safe_glob().
<?php
/**
* Prepends $string to each element of $array
* If $deep is true, will indeed also apply to sub-arrays
* @author BigueNique AT yahoo DOT ca

*/
function array_prepend($array, $string, $deep=false) {
if(empty($array)||empty($string)) return $array;
foreach($array as $key => $element)
if(is_array($element))
if($deep)
$array[$key] = array_prepend($element,$string,$deep);
else
trigger_error('array_prepend: array element',E_USER_WARNING);
else
$array[$key] = $string.$element;
return $array;
}

in the example below, i found i got an error if the directory was empty.
<?php
foreach (glob("*.txt") as $filename) {
echo "$filename size " . filesize($filename) . "\n";
}
?>
I think its because glob()'ing an empty directory returns false, and so calling foreach (false as $value) will obviously break.
to fix this, i did the following:
<?php
$files = glob("*.txt) or array(); // give it an empty array if the directory is empty or glob fails otherwise
echo "$filename size " . filesize($filename) . "\n";
}
?>
Hope this helps someone

A couple of notes:
glob() handles symbolic filesystem links and resolves references to './', '../' nicely and handles an extra '/' character , at least on X-systems. e.g., glob("../*") will do next higher dir.
This is good to use so warnings or errors show as "../foo" and not your system's full path.
Several of the examples use a notation "*.*" when just plain "*" does the same thing. The "*.*" notation is misleading as it implies foo.ext will not be found with "*" because the "." is not present.
Watch the flags must not be strings. They are defined constants. Thus,
glob("../*", GLOB_ONLYDIR) works;
glob("../*", "GLOB_ONLYDIR") does not.

I have been working towards a CMS-type design that is both modular and quite flat. For example, included files are all one level below the installation folder.
glob() just help me get rid of a lot of opendir() hassle. I wasn't sure if the double asterix would work - but it's fine:
foreach (glob(SERVER_PATH."/*/includes/*.php") as $inc) {
require($inc);
}

It is also possible to nest alternations like this:
<?php
foreach (glob("{$dir}/*.{[jJ][pP]{,[eE]}[gG],[tT][iI][fF]{,[fF]}}", GLOB_BRACE) as $file) {
// finds both .jp(e)g and .tif(f) files
// please note that you should double-check the file type, though
}

Here is basic PHP code to do a recursive scan of an entire directory tree, allowing you to do processing when reaching each directory and file:
// Do a recursive scan of an entire directory tree,
// starting with the current working directory
// using relative filepaths
// Includes files starting with '.'
// Minimally tested on Windows and Linux
Scan('.');
function Scan($dir)
{
// Add code for each directory $dir here
$subdirs=glob($dir.'/{.[!.],}*',GLOB_BRACE);
foreach ($subdirs as $file)
{
if (is_file($file))
{
// Add code for each file $file here
}
else if (substr($file,0,1)!='./.')
Scan($file);
}
} // Scan

Note that if you use braces ie. /*.{gif,jpg,htm} then glob returns
gifs before jpgs before htm files rather than in filename sequence.

Brackets in the pattern maust be bracketed:
Filename = " [Fail2Ban] recidive *.eml"
The pattern should be:
$pattern = '[[]Fail2Ban[]] recidive *.eml';
Otherwise the brackets will be treated as character class identifier.

Note that when the documentation says the files will be returned in "alphabetical" order, you may not get the results you expect if your files are numbered.
For example, files will be returned in the following order:
file.1.txt
file.10.txt
file.2.txt
Not (as you might expect):
file.1.txt
file.2.txt
file.10.txt

I created a rglob function to support a '/**/' wildcard. You can even set the order to post-order or pre-order traversal.
<?php
function rglob ($pattern, $flags = 0, $traversePostOrder = false) {
// Keep away the hassles of the rest if we don't use the wildcard anyway
if (strpos($pattern, '/**/') === false) {
return glob($pattern, $flags);
}
$patternParts = explode('/**/', $pattern);
// Get sub dirs
$dirs = glob(array_shift($patternParts) . '/*', GLOB_ONLYDIR | GLOB_NOSORT);
// Get files for current dir
$files = glob($pattern, $flags);
foreach ($dirs as $dir) {
$subDirContent = rglob($dir . '/**/' . implode('/**/', $patternParts), $flags, $traversePostOrder);
if (!$traversePostOrder) {
$files = array_merge($files, $subDirContent);
} else {
$files = array_merge($subDirContent, $files);
}
}
return $files;
};

After fiddling with GLOB_BRACE a bunch, I have found the most items that can be included in the braces is about 10 before glob no longer returns any matches.
I have a scenario where there can be a thousand or more files to check for where I can't pattern match and need to check specific names. I was hoping to batch them in large groups to see if it would help performance. However, if I include more than 10 in a GLOB_BRACE the function will return FALSE.

Something I used to sort dir & subdir into array (multidimensional) reflecting dir structure.
function getRecursiveFolderList($curDir,$currentA=false)
{
$dirs = glob($curDir . '/*', GLOB_ONLYDIR);
$cur = 0;
foreach($dirs as $dir)
{
$currentA[$cur]['path'] = $dir;
$currentA[$cur] = $this->getRecursiveFolderList($dir,$currentA[$cur]);
++$cur;
}
return $currentA;
}

Here is simple function that will find and remove all files (except "." ones) that match the expression ($match, "*" as wildcard) under starting directory ($path) and all other directories under it.
function rfr($path,$match){
static $deld = 0, $dsize = 0;
$dirs = glob($path."*");
$files = glob($path.$match);
foreach($files as $file){
if(is_file($file)){
$dsize += filesize($file);
unlink($file);
$deld++;
}
}
foreach($dirs as $dir){
if(is_dir($dir)){
$dir = basename($dir) . "/";
rfr($path.$dir,$match);
}
}
return "$deld files deleted with a total size of $dsize bytes";
}

Whilst on Windows, a path starting with a slash resolves OK for most file functions - but NOT glob.
If the server is LAUNCHED (or chdir()ed) to W:, then
file_exists("/temp/test.txt")
returns true for the file "W:/temp/test.txt".
But glob("/temp/*.txt") FAILS to find it!
A solution (if you want to avoid getting drive letters into your code) is to chdir() first, then just look for the file.
<?php
$glob="/temp/*.txt";
chdir(dirname($glob));
// getcwd() is now actually "W:\temp" or whatever
foreach (glob(basename($glob)) as $filename) {
$filepath = dirname($glob)."/".$filename; // must re-attach full path
echo "$filepath size " . filesize($filepath) . "\n";
}
?>
Note also, glob() IS case sensitive although most other file funcs on Windows are not.
