Do note that this command has a security hole.
If the $path or $pattern given includes special characters, for example a command substitution such as "`rm index.php`", the shell will process it and execute that command.
You can fix the problem by either escaping the characters properly (use shell_escape) or by writing a function that actually calls glob(), or opendir()/readdir()/closedir(), recursively.
glob
(PHP 4 >= 4.3.0, PHP 5)
glob — パターンにマッチするパス名を探す
説明
array glob
( string $pattern
[, int $flags
] )
glob() 関数は libc の glob() 関数で使われるルールに基づいて pattern にマッチする全てのパス名を検索します。 ルールは、一般のシェルで使われるルールと似ています。
パラメータ
- pattern
-
パターン。チルダの展開やパラメータ置換は行いません。
- flags
-
有効なフラグは次のとおりです。
- GLOB_MARK - 各戻り値にスラッシュを追加します
- GLOB_NOSORT - ディレクトリに存在するファイルを返します (ソートはされません)
- GLOB_NOCHECK - 検索パターンにマッチするファイルが見つからない場合に、 検索パターン自身を返します
- GLOB_NOESCAPE - バックスラッシュによるメタ文字のクォートを行いません
- GLOB_BRACE - {a,b,c} を展開し「a」、「b」あるいは「c」のいずれかにマッチさせます
- GLOB_ONLYDIR - パターンにマッチするディレクトリのみを返します
- GLOB_ERR - (ディレクトリが読めないなどの) 読み込みエラー時に停止します。デフォルトではエラーは無視されます。
返り値
マッチするファイル／ディレクトリを含む配列を返します。 マッチするファイルがなかった場合には空の配列、 そして失敗した場合には FALSE を返します。
変更履歴
| バージョン | 説明 |
|---|---|
| 5.1.0 | GLOB_ERR が追加されました。 |
| 4.3.3 | PHP 4.3.3 以前では、GLOB_ONLYDIR が、 Windows やその他の GNU C ライブラリを使用しないシステムでも利用できるようになりました。 |
例
Example#1 glob() が opendir() と関連する関数群の代替策になるかを示す簡便な方法
<?php
foreach (glob("*.txt") as $filename) {
echo "$filename size " . filesize($filename) . "\n";
}
?>
上の例の出力は、たとえば 以下のようになります。
funclist.txt size 44686 funcsummary.txt size 267625 quickref.txt size 137820
注意
注意: この関数では、 リモートファイル を 使用することはできません。これは、処理されるファイルがサーバの ファイルシステムによりアクセスできる必要があるためです。
注意: この関数が使用できないシステムも存在します (例: 昔の Sun OS など)。
注意: GLOB_BRACE フラグは、Solaris などの非 GNU システムでは動作しないことがあります。

Here's a function that behaves as a recursive glob(). It does rely on shell command find, but works like a charm.
function glob_rec($pattern, $path) {
return explode("\n", shell_exec("find $path -name $pattern"));
}

As mentioned below, characters like [ and ] cause problems and need to be escaped with a backslash. But it's *not* enough to escape them in the pattern itself! If they appear in the path to the working directory, glob() also fails!
So, if this fails:
glob('*.txt');
Try:
glob(preg_quote(getcwd() . DIRECTORY_SEPARATOR) . '*.txt');

Run your directory + "file pattern" through preg_quote to get around [ ] / etc issues...glob uses pattern matching.

glob() does not work if the path contains brackets "[" and "]".
For example, this will make it fail:
$files = glob("[myfolder]/*.txt");
No error is returned, just an empty array!

Hi there,
if you backslash the brackets, it should work. Try:
$files = glob("\[myfolder\]/*.txt");
Hope this helps.

An alternative to this glob function. Like what edogs [at] dogsempire.com said, opendir should be faster than glob. I have not tested timing for this function but it works perfectly for me on my PHP v5.2.2 server.
<?php
$_foo ='/server/public_html/path/';
function s_glob($dir){
$files = array();
if(is_dir($dir)){
if($dh=opendir($dir)){
while(($file = readdir($dh)) !== false){
$files[]=$dir.$file;
}}
}
return $files;
}
print_r(s_glob($_foo));
?>
This function returns an empty array if no files are found in the directory or the path specified is not a directory.

if your script runs in a directory which contains brackets "[" and "]" glob does not work. example:
script path: c:/dir1/[baddir]/dir2/script.php
íf you use glob("c:/*") or similar calls in this script, it will fail!!
you do not even have to use the brackets in the first parameter of glob!

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;
}

Reply to ny_obaATgmxDOTnet:
You could also use sql_regcase() to build a pattern for case insensitive matches.
You may also want to set the locale before, so it is used when building the pattern.
<?php
$pattern = sql_case("*.pdf");
var_dump(glob($pattern));
?>
should therefore match file.pdf AND OtherFile.PDF
See http://www.php.net/sql_regcase for more information.

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.

Maybe all of you still know this, but it seems that if the directory contains some unresolved symlink, glob() simply ignore those files.

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";

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";

The answer for the difference in the dirsize function of "management at twilightus dot net":
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 ..

I was making a directory filesize function but found there's a slight difference between glob and readdir in terms of getting sizes.
<?php
function dirsize_glob($dir)
{
$size = 0;
$dir .= (!ereg('/$', $dir)) ? '/' : '';
foreach (glob($dir . '*') as $file)
{
$size += (is_dir($file)) ? dirsize_glob($file) : filesize($file);
}
return $size;
}
function dirsize_readdir($dir)
{
$size = 0;
$dir .= (!ereg('/$', $dir)) ? '/' : '';
$handle = opendir($dir);
while (($file = readdir($handle)) !== FALSE)
{
if (!ereg('^\.{1,2}$', $file))
{
$size += (is_dir($dir . $file)) ? dirsize_readdir($dir . $file) : filesize($dir . $file);
}
}
closedir($handle);
return $size;
}
?>
For a directory that's 529216 bytes, readdir correctly gives 529216 while glob gives 528996, a difference of 220 bytes. Anyone know why there's such a difference?

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);

I've written a function that I've been using quite a lot over the past year or so. I've built whole websites and their file based CMSs based on this one function, mostly because (I think) databases are not as portable as groups of files and folders. In previous versions, I used opendir and readdir to get contents, but now I can do in one line what used to take several. How? Most of the work in the whole script is done by calling
glob("$dir/*")
Giving me an array containing the names of the items in the folder, minus the ones beginning with '.', as well as the ones I specify.
<?php
/* alpharead version 3: This function returns an array containing the names of the files inside any given folder, excluding files that start with a '.', as well as the filenames listed in the '$killit' array. This array is sorted using the 'natural alphabetical' sorting manner. If no input is given to the function, it lists items in the script's interpreted folder. Version 3 fixes a MAJOR bug in version 2 which corrupted certain arrays with greater than 5 keys and one of the supposedly removed filenames.

function alpharead3($dir){
if(!$dir){$dir = '.';}
foreach(glob("$dir/*") as $item){$sort[]= end(explode('/',$item));}
$killit = array('index.html', 'index.php', 'thumbs.db', 'styles.css');
$killcounter = 0;
foreach($sort as $sorteditem){
foreach($killit as $killcheck){
if(strtolower($sorteditem) == strtolower($killcheck))
{unset($sort[$killcounter]);}
}$killcounter++;}
if($sort){natsort($sort);}
foreach($sort as $item){$return[]= $item;}
if(!$return){return array();}
return $return;

//some basic usage

Note that on Windows, glob distinguishes between uppercase and lowercase extensions, so if the directory contains a file "test.txt" and you glob for "*.TXT" then the file will not be found!
That bug only happens when you use patterns containing "*", like the example above. If you for example search for the full filename "test.TXT" then everything works correctly.

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.

This is a replacement for glob on servers that are running a php version < 4.3
It supports * and ? jokers, and stacking of parameters with ;
So you can do
<? $results=glob('/home/user/*.txt;*.doc') ?>
And it will return an array of matched files.
As is the behaviour of the built-in glob function, this one will also return boolean false if no matches are found, and will use the current working directory if none is specified.
<?php
if(!(function_exists('glob')))
{function glob($pattern)
{#get pathname (everything up until the last / or \)
$path=$output=null;
if(PHP_OS=='WIN32')
$slash='\\';
else
$slash='/';
$lastpos=strrpos($pattern,$slash);
if(!($lastpos===false))
{$path=substr($pattern,0,-$lastpos-1); #negative length means take from the right
$pattern=substr($pattern,$lastpos);
}
else
{#no dir info, use current dir
$path=getcwd();
}
$handle=@ opendir($path);
if($handle===false)
return false;
while($dir=readdir($handle))
{if(pattern_match($pattern,$dir))
$output[]=$dir;
}
closedir($handle);
if(is_array($output))
return $output;
return false;
}
function pattern_match($pattern,$string)
{#basically prepare a regular expression
$out=null;
$chunks=explode(';',$pattern);
foreach($chunks as $pattern)
{$escape=array('$','^','.','{','}',
'(',')','[',']','|');
while(strpos($pattern,'**')!==false)
$pattern=str_replace('**','*',$pattern);
foreach($escape as $probe)
$pattern=str_replace($probe,"\\$probe",$pattern);
$pattern=str_replace('?*','*',
str_replace('*?','*',
str_replace('*',".*",
str_replace('?','.{1,1}',$pattern))));
$out[]=$pattern;
}
if(count($out)==1)
return(eregi("^$out[0]$",$string));
else
foreach($out as $tester)
if(eregi("^$tester$",$string))
return true;
return false;
}
}
?>
This function is case insensitive, but if needed, you can do this to make it behave depending on os:
* replace eregi in the example with my_regexp
add this function
<?php
function my_regexp($pattern,$probe)
{$sensitive=(PHP_OS!='WIN32');
$sensitive=false;
return ($sensitive?
ereg($pattern,$probe):
eregi($pattern,$probe));
}
?>

In regards to the comments made by: NOSPAM sketch at infinite dot net dot au, he is wrong about Unix/Linux (I can't speak for Windows). I am running PHP 5.0.4 and I ran a bunch of different tests on relative and absolute paths using the glob function and they all work on Unix/Linux. I also tested glob on empty directories and patterns which don't match any files (even directories or files which don't exist) and it __always__ returns an empty array. I couldn't get the glob function to return false so it looks like it always returns an array.

Here is a way I used glob() to browse a directory, pull the file name out, resort according to the most recent date and format it using date(). I called the function inside a <select> and had it go directly to the PDF file:
function browsepdf(){
$pdffile=glob("printable/*.pdf");
rsort($pdffile);
foreach($pdffile as $filename){
$filename=ltrim($filename, "printable/");
$filename=rtrim($filename, ".pdf");
$file=$filename;
$datetime=strtotime($filename);
$newdate=strtotime("+3 days",$datetime);
$filenamedate=date("F d", $datetime);
$filenamedate.=" - ".date("F d, Y", $newdate);
echo "<option value='$file'>$filenamedate</option>";
}
}

glob caused me some real pain in the buttom on windows, because of the DOS thing with paths (backslashes instead of slashes)...
This was my own fault because I "forgot" that the backslash, when used in strings, needs to be escaped, but well, it can cause a lot of confusion, even for people who are not exactly newbies anymore...
For some reason, I didn't have this problem with other file operations (chdir, opendir, etc...), which was the most confusing of all...
So, for people running scripts on Windows machines (Dos95, 98 or WinNT or DosXP), just remember this:
glob('c:\temp\*.*'); // works correctly, returns an array with files.
glob("c:\temp\*.*"); // does NOT work... the backslashes need to be escaped...
glob("c:\\temp\\*.*"); // that works again...
This is especially confusing when temporary writable directories are returned as an unescaped string.
$tempdir = getenv('TEMP');
// this returns "C:\DOCUME~1\user\LOCALS~1\Temp"
so in order to scan that directoy I need to do:
glob($tempdir . "\\*.*");
Or perhaps it's easier to replace all backslashes with slashes in order to avoid these kinds of confusions...
glob("c:/temp/*.*"); // works fine too...
I know I'm not contributing anything new here, but I just hope this post may avoid some unnecessary headaches...

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

Be aware...
On Windows you need to add "/" mark:
<?php
$files = glob("/dir/*.txt"); // Works properly.
$files = glob("dir/*.txt"); // Failure!, first letter is missing on every filename!
?>
On Unix you cant add the "/" mark:
<?php
$files = glob("dir/*.txt"); // Works properly.
$files = glob("/dir/*.txt"); // No files found!
?>
Hope this will save your time :)

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";
}
}
?>

Just threw this together in response to a common question in irc:
Available at: http://www.pgregg.com/projects/
http://www.pgregg.com/projects/php/code/preg_find.phps
preg_find() - A function to search in a directory for files or directories matching a preg_ pattern. Tell it the pattern, the start directory and some optional flags and it will return an array of files and their associated stat() details. If you just want the filenames, just do an array_keys() on the result.
e.g. $files = preg_find("/\.php$/", '.', PREG_FIND_RECURSIVE);
will find all files ending in .php in the current directory and below.
Options are:
// PREG_FIND_RECURSIVE - go into subdirectorys looking for more files
// PREG_FIND_DIRMATCH - return directorys that match the pattern also
// PREG_FIND_FULLPATH - search for the pattern in the full path (dir+file)
// PREG_FIND_NEGATE - return files that don't match the pattern
// to use more than one simple seperate them with a | character
Hope you find it useful.
Paul.

Be aware that on UNIX, * as the pattern will *not* match dot-files and dot-directories. Knowing this will save you some headache. :-) May He bless you.

Note that, in some configurations, the search is case-sensitive! You'll need to have something like:
<?php
$images = glob("/path/to/images/{*.jpg,*.JPG}", GLOB_BRACE);
?>
Also on some servers, I have seen such scripts 'crash' with an CGI Error ("...not returning a complete set of HTTP headers...") when glob could not find any match!

Here's an example of how to use the GLOB_BRACE flag:
<?php
$images = glob("/path/to/images/{*.gif,*.jpg,*.png}", GLOB_BRACE);
?>
It's also worth noting that when using the GLOB_BRACE flag in any version of PHP prior to 4.3.4, PHP will crash if no matches are found.

If you don't have PHP >= 4.3 available and don't want to hassle with PHP (:-) do something like this on GNU/Linux:
<?php
foreach (explode("\n",`find -type d -maxdepth 1 ! -name ".*" -printf "%f\n" `) as $dirname) {
print $dirname;
}
?>
With the "find" you can "glob" whatever you like.

I have written my own function for searching files, but it only supports ? and *
However it should be easily expandable.
<?php
// e.g. $matches=GetMachingFiles(GetContents("."),"*.txt");
function GetMatchingFiles($files, $search) {
// Split to name and filetype
if(strpos($search,".")) {
$baseexp=substr($search,0,strpos($search,"."));
$typeexp=substr($search,strpos($search,".")+1,strlen($search));
} else {
$baseexp=$search;
$typeexp="";
}
// Escape all regexp Characters
$baseexp=preg_quote($baseexp);
$typeexp=preg_quote($typeexp);
// Allow ? and *
$baseexp=str_replace(array("\*","\?"), array(".*","."), $baseexp);
$typeexp=str_replace(array("\*","\?"), array(".*","."), $typeexp);
// Search for Matches
$i=0;
foreach($files as $file) {
$filename=basename($file);
if(strpos($filename,".")) {
$base=substr($filename,0,strpos($filename,"."));
$type=substr($filename,strpos($filename,".")+1,strlen($filename));
} else {
$base=$filename;
$type="";
}
if(preg_match("/^".$baseexp."$/i",$base) && preg_match("/^".$typeexp."$/i",$type)) {
$matches[$i]=$file;
$i++;
}
}
return $matches;
}
And if someone's searching for a function which gets all files from a directory including the subdirectories:
// Returns all Files contained in given dir, including subdirs
function GetContents($dir,$files=array()) {
if(!($res=opendir($dir))) exit("$dir doesn't exist!");
while(($file=readdir($res))==TRUE)
if($file!="." && $file!="..")
if(is_dir("$dir/$file")) $files=GetContents("$dir/$file",$files);
else array_push($files,"$dir/$file");
closedir($res);
return $files;
}
?>

Since this function is a wrapper for the OS function of the same name, you may find it helpful to look at the man page while the exact PHP implementation is sorted out.
You might have some luck passing in the literal values of the constants defined in /usr/include/glob.h. For example, GLOB_NOSORT is defined as (1 << 2), which is 4. In PHP, glob('*.php', 4) will returns an unsorted list for me in RH 7.x. YMMV.

If this function is not available in your version of PHP, think looking at the 'Directory Functions' which can be used instead.
