This is an annotation from Stig Bakken:
The mode on your directory is affected by your current umask. It will end
up having (<mkdir-mode> and (not <umask>)). If you want to create one
that is publicly readable, do something like this:
<?php
$oldumask = umask(0);
mkdir('mydir', 0777); // or even 01777 so you get the sticky bit set
umask($oldumask);
?>
mkdir
(PHP 4, PHP 5)
mkdir — Makes directory
Description
bool mkdir
( string
$pathname
[, int $mode = 0777
[, bool $recursive = false
[, resource $context
]]] )Attempts to create the directory specified by pathname.
Parameters
-
pathname -
The directory path.
-
mode -
The mode is 0777 by default, which means the widest possible access. For more information on modes, read the details on the chmod() page.
Note:
modeis ignored on Windows.Note that you probably want to specify the mode as an octal number, which means it should have a leading zero. The mode is also modified by the current umask, which you can change using umask().
-
recursive -
Allows the creation of nested directories specified in the
pathname. -
context -
Note: Context support was added with PHP 5.0.0. For a description of contexts, refer to Streams.
Return Values
Returns TRUE on success or FALSE on failure.
Changelog
| Version | Description |
|---|---|
| 5.0.0 |
The recursive parameter was added
|
| 5.0.0 | As of PHP 5.0.0 mkdir() can also be used with some URL wrappers. Refer to Supported Protocols and Wrappers for a listing of which wrappers support mkdir() |
| 4.2.0 |
The mode parameter became optional.
|
Examples
Example #1 mkdir() example
<?php
mkdir("/path/to/my/dir", 0700);
?>
Example #2 mkdir() using the recursive parameter
<?php
// Desired folder structure
$structure = './depth1/depth2/depth3/';
// To create the nested structure, the $recursive parameter
// to mkdir() must be specified.
if (!mkdir($structure, 0, true)) {
die('Failed to create folders...');
}
// ...
?>
Notes
Note: When safe mode is enabled, PHP checks whether the directory in which the script is operating has the same UID (owner) as the script that is being executed.

If you have problems with the SAFE MODE Restriction in effect i.e. if you try to create and access to subdirectorys recursive you can use ftp-lib like this.
<?php
DEFINE ('FTP_USER','yourUser');
DEFINE ('FTP_PASS','yourPassword');
/**
* Returns the created directory or false.
*
* @param Directory to create (String)
* @return Created directory or false;
*/
function mkDirFix ($path) {
$path = explode("/",$path);
$conn_id = @ftp_connect("localhost");
if(!$conn_id) {
return false;
}
if (@ftp_login($conn_id, FTP_USER, FTP_PASS)) {
foreach ($path as $dir) {
if(!$dir) {
continue;
}
$currPath.="/".trim($dir);
if(!@ftp_chdir($conn_id,$currPath)) {
if(!@ftp_mkdir($conn_id,$currPath)) {
@ftp_close($conn_id);
return false;
}
@ftp_chmod($conn_id,0777,$currPath);
}
}
}
@ftp_close($conn_id);
return $currPath;
}
?>
Maybe it helps.

Here's a script to create a recursive directory path on NAS or another server using Common Internet File System (CIFS)
e.g. you already have a directory on a server
\\server/share/dir1/dir2
you want to create some more directories
\\server/share/dir1/dir2/dir3/dir4
<?php
function remote_mkpath($server, $path) {
$dirs = array();
$path = preg_replace('/(\/){2,}|(\\\){1,}/','/',$path); //only forward-slash
$dirs = explode("/", $path);
$path = "\\\\" . $server . "/";
$i = 0;
foreach ($dirs AS $element) {
$path .= $element . "/";
if(!is_dir($path) && $i != 0) {
if(!mkdir($path)){
echo "something was wrong at : " . $path;
return 0;
}
}
$i++;
}
return true;
echo $path;
}
// example usage
remote_mkpath("SERVER", "share/dir1/dir2/dir3/dir4");
?>
Good luck!

On the other hand, splitting path on something else then a DIRECTORY_SEPARATOR may give unexpected results when someone accualy wants a file name with backslash in it! Moreover, neither Alan's nor pluto's code check for errors or return any value. Also, I don't like the isset($folder[$i]) technique -- there is a count() function you know.
<?php
function recursive_mkdir($path, $mode = 0777) {
$dirs = explode(DIRECTORY_SEPARATOR , $path);
$count = count($dirs);
$path = '.';
for ($i = 0; $i < $count; ++$i) {
$path .= DIRECTORY_SEPARATOR . $dirs[$i];
if (!is_dir($path) && !mkdir($path, $mode)) {
return false;
}
}
return true;
}
?>
It will only fail if someone specifies a mode which does not allow owner to create new entries in directory.

Greg, your code does not work for me; maybe it has a bug or we have configuration changes. Anyway, this one works to create recursively the directory DIRECTORY.
<?
define ("DIRECTORY", "/tmp/mydir/mysubdir");
do {
$dir = DIRECTORY;
while (!is_dir($dir)) {
$basedir = dirname($dir);
if ($basedir == '/' || is_dir($basedir))
mkdir($dir,0777);
else
$dir=$basedir;
}
} while ($dir != DIRECTORY);
?>

if you are unable to create recursive folder(s) using 0755 mode in your php script.
Then try it by changing your current user to apache and test it again.
Hopefully you will get positive results

Remember to use clearstatcache()
... when working with filesystem functions.
Otherwise, as an example, you can get an error creating a folder (using mkdir) just after deleting it (using rmdir).

It should be mentioned that - at least on Windows - when using UNC paths with mkdir the 2nd parameter $mode should not be specified. Otherwise mkdir fails to create the directory on the given UNC path.
jack dot sleight at gmail dot com ¶

When using the recursive parameter bear in mind that if you're using chmod() after mkdir() to set the mode without it being modified by the value of uchar() you need to call chmod() on all created directories. ie:
<?php
mkdir('/test1/test2', 0777, true);
chmod('/test1/test2', 0777);
?>
May result in "/test1/test2" having a mode of 0777 but "/test1" still having a mode of 0755 from the mkdir() call. You'd need to do:
<?php
mkdir('/test1/test2', 0777, true);
chmod('/test1', 0777);
chmod('/test1/test2', 0777);
?>

Please note that when specifying the recursive option the function returns false anyway if the directory already exists.
For some reason however I expected it to behave like `mkdir -p` on the command line which succeeds if the directory already exists.

It should be noted that all of the recursive mkdir functions coded below are no longer required - as of 5.0.0 it says the "recursive" flag is available. I just tested it, it properly works (and I would assume it works for streams and Windows as well, if not, then it would be a bug)

One small correction on a note from Frank in June 2006 on recursive directories under Windows.
First - this should be in the documentation as its the only function that I know of that php does not fix the slashes automatically.
Franks note stated:
<?php
$mypath="testdir\subdir\test";
mkdir($mypath,0777,TRUE);
?>
This doesn't work in windows:
<?php
$mypath="testdir/subdir/test";
mkdir($mypath,0777,TRUE);
?>
----
This will work a bit better :)
<?php
$mypath="testdir\\subdir\\test";
mkdir($mypath,0777,TRUE);
?>

You might notice that when you create a new directory using this code:
mkdir($dir, 0777);
The created folder actually has permissions of 0755, instead of the specified
0777. Why is this you ask? Because of umask(): http://www.php.net/umask
The default value of umask, at least on my setup, is 18. Which is 22 octal, or
0022. This means that when you use mkdir() to CHMOD the created folder to 0777,
PHP takes 0777 and substracts the current value of umask, in our case 0022, so
the result is 0755 - which is not what you wanted, probably.
The "fix" for this is simple, include this line:
$old_umask = umask(0);
Right before creating a folder with mkdir() to have the actual value you put be
used as the CHMOD. If you would like to return umask to its original value when
you're done, use this:
umask($old_umask);

I was able to resolve this problem by ensuring the containing folder had write permission enabled (CHMOD 775) where I wanted to create a new folder.
As others have said, it's worth checking, then double checking, the permissions.
matt at imaketheweb dot com ¶

If you're getting a Permission Denied error, but are certain the permissions and ownership where you are trying to create the directory are correct, check again:
The location where you are trying to create the directory in must have the Execute permission for the owner trying to create it, regardless of if the folder is Readable, or Writable.
This may be obvious to some, but was not to me at first. Hopefully this will save you the trouble I went through.
nickcarenza at gmail dot com ¶

If you are having trouble with the pathname, use:
echo dirname( __FILE__ );
That will show you the pathname of the current script and you will be able to use that to see where you have to start your pathname.
I tried forever to do mkdir('dirname') and was getting permission denied. I can see now its because it was trying to create that folder up at home when i wanted it down in public_html.
I hope this saves someone some time.

Please note that in a shared environment I failed to take into account an existing umask when I did a mkdir(dirname, 0755). This ended up creating the directory (function returned true), but I didn't have rights to do anything inside the folder, nor could I even view that it existed via ftp.
However, file_exists(dirname) returned true. Eventually I figured out what happened and was able to rmdir(dirname), then created the directory correctly.
So, when writing scripts you expect to be portable, either use umask to set your umask accordingly, or do a straight mkdir(dirname) followed by chmod(dirname, 0755) (or whatever it is you're looking for). If you make the same mistake I did, you should be able to rmdir() or chmod() the folder so it's accessible.

It can use with another functions about file system as file_put_contents to clean up file name.

p-garcia : since PHP 5, setting the recursive flag (which currently has no notes in the manual entry) will allow you to create nested directories in the same way as Windows / Linux mkdir -p, so long as the webserver has permissions to write in the root directory of the path specified
eg:
<?php
mkdir ("./newdir1/newdir2/newdir3/", 0755, true);
// Returns TRUE if you have permission to write to the current directory
// and creates nested directories with permissionsrwxr-xr-x
?>
kendsnyder at gmail dot com ¶

When creating directories in Windows, trailing periods (".") are ignored. for example:
<?php
mkdir('c:/Buck Jr.',0755); // on Windows creates "c:/Buck Jr"
mkdir('c:/Elipses...',0755); // on Windows creates "c:/Elipses"
mkdir('c:/php.com',0755); // on Windows creates "c:/php.com"
?>
This is a Window's quirk, not a php shortcoming--meaning that you get the same results from a Window's command prompt.

It should be noted that although the documentation says that the default permissions for mkdir are 0777, this is not always the case.
I'm running LAMP and without explicitly setting the permissions, the directories created had permissions of 0755.

Somehow the recursive version of mkdir didn't work for me on Mac and the workaraounds listed below alsow didn't work for me, so heres my solution:
<?php
function mkdir_r($dirName, $rights=0777){
$dirs = explode('/', $dirName);
$dir='';
foreach ($dirs as $part) {
$dir.=$part.'/';
if (!is_dir($dir) && strlen($dir)>0)
mkdir($dir, $rights);
}
}
?>
Tested and works ;)

one small gotcha:
mkdir(""), mkdir(false), and mkdir(null) give a "file exists" error. this is also true of a directory name consisting of any string that only contains space characters.
(this was on php 5.1.2 on Windows 2000)
bat at flurf dot net ¶

A little understanding of LISPlike programming makes this sort of task (recursive mkdir()ing in PHP4) much simpler. This version works nicely:
<?php
function MakeDirectory($dir, $mode = 0755)
{
if (is_dir($dir) || @mkdir($dir,$mode)) return TRUE;
if (!MakeDirectory(dirname($dir),$mode)) return FALSE;
return @mkdir($dir,$mode);
}
?>
How it works: line one attempts to make the directory, and returns TRUE if it works or if it already exists. That's the easy case if the parent directories all exist.
Line two trims off the last directory name using dirname(), and calls MakeDirectory recursively on that shorter directory. If that fails, it returns FALSE, but otherwise we come out of it knowing that the parent directory definitely exists.
Finally, presuming the recursive call worked, once we get to line three we can create the requested directory.
Note the use of @ to suppress warning messages from mkdir.
The beauty of this is that if, say, the great-grandparent directory exists but the grandparent and parent directories don't, the function will simply call itself recursively until it gets high enough up the tree to do some work, then carry on unwinding back until all the new directories have been created.
This is pretty bog-standard recursive programming. Anyone who can't wrap their head around it after a few minutes of concentration should probably try a career in sales.

I could not get the sticky bit set properly using the octal mode: 2775 (rwxrwsr-x)
$foo='my_directory';
$old_umask = umask(0);
mkdir($foo,2775);
umask($old_umask);
using the above lines renders a directory with permissions:
d-wx-wSrwt 2 www www 4096 Nov 2 11:43 my_directory
Not exactly what I was looking for.
This gets closer to the mark:
$foo='my_directory';

The 'mkdir' function doesn't function correctly on Windows when the path

doesn't get created.
mkdir('c:/a/b/c/d', 0775, true);
You get the error message:
Warning: mkdir() [function.mkdir]: No such file or directory
Please use backslashes under Windows or use the constant DIRECTORY_SEPARATOR.
mkdir('c:\a\b\c\d', 0775, true);

mkdir, file rw, permission related notes for Fedora 3////
If you are using Fedora 3 and are facing permission problems, better check if SElinux is enabled on ur system. It add an additional layer of security and as a result PHP cant write to the folder eventhough it has 777 permissions. It took me almost a week to deal with this!
If you are not sure google for SElinux or 'disabling SELinux' and it may be the cure! Best of luck!

sometimes the directory created with another mode than specified ( 0755 instead 0777 etc).

Note that you should NOT enter the $mode value with "" or '' sorrounding it.
So, this should be valid:
<?php mkdir("dir1/dir2",0777,true); ?>
But this is not:
<?php mkdir("dir1/dir2","0777",true); ?>
Nor this:
<?php mkdir("dir1/dir2",'0777',true); ?>

After a long time trying to catch the cause of the warning: "mkdir() [function.mkdir]: No such file or directory", I finally realized that this function is not recursive; I mean, that if you want to create the folder -for example- c:\temp\t1\t2, you must do:
mkdir("c:\\temp\\t1") ;
mkdir("c:\\temp\\t1\\t2") ;
because mkdir is not like the windows mkdir where you can acomplish this in one single step.

I've discovered that since my (shared) hosting provider upgraded to PHP 5.1.6 , a script containing this mkdir doesn't work:
<?php
mkdir('/home/benge/photos/gallery1/extra_large/', 0777);
?>
but this does work:
<?php
mkdir('/home/benge/photos/gallery1/extra_large', 0777);
?>
the difference being, the trailing slash "/" after "extra_large.
There were three ways to fix the problem:
1. remove the trailing slash from the script code
2. downgrade to < PHP 5.1.6
3. turn safe mode off
I went with option 1.

Re: john 4t idserver d0t org, and djneoform at gmail dot com's posts from 27 Oct 2006:
On Windows systems, several keywords are reserved and cannot be used as filenames, in addition to just CON and PRN. Attempting to create a folder with one of these names using mkdir will throw the unhelpful error "Invalid argument". According to http://msdn.microsoft.com/library/default.asp ?url=/library/en-us/fileio/fs/naming_a_file.asp :
"Do not use the following reserved device names for the name of a file: CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9. Also avoid these names followed by an extension, for example, NUL.tx7.
Windows NT: CLOCK$ is also a reserved device name."
These keywords are also case-insensitive. I don't know what problems are posed by using these keywords with extensions, but I successfully created a folder named "con_f".

When safe_mode is enabled, and you create a directory via mkdir, you can't create a second inside the first because the first folder's user is that one of the webserver and not that one of the script. This is dumb and very annoying :(

I've been wrestling with mkdir on a server with safe mode turned on (I think, I kept getting barmy permissions on the new dirs).
In the end the solution was to use:
exec (mkdir ...
exec (chmod ...
For this to work I had to use the setuid bit on the script itself. I tried this with the mkdir() function, but to no avail. (To do the setuid bit I ran chmod 4775 on the script file from the command line.)
