PHP: mkdir - Manual

Beschrijving

bool mkdir ( string pathname [, int mode])

Probeert de folder pathname aan te maken.

Waarschijnlijk wil je de mode als een octale waarde meegeven, wat betekent dat je er een begin 0 voor moet zetten. De mode wordt ook bewerkt door de huidige umask, die je kan veranderen met umask().

Opmerking: Mode wordt genegeerd onder Windows, en is optioneel geworden in PHP 4.2.0.

De modus is standaard 0777, wat de breedst mogelijke toegang betekent. Voor meer informatie over modus, lees de details op de chmod() pagina.


<?php

mkdir ("/path/to/my/dir", 0700);

?>

Geeft TRUE terug bij succes, FALSE indien er een fout is opgetreden.

Zie ook rmdir().

Right after you make a dir you should put chdir in order to be able to read that dir, otherwise you get an error message.



$dirupload = 'D:/server/images/';



mkdir ($dirupload, 0700);



chdir('./');



Hope it helps someone.

Here is a better function to create multiple directories :



    function mkDirE($dir,$dirmode=700)

    {

        if (!empty($dir))

        {

            if (!file_exists($dir))

            {

                preg_match_all('/([^\/]*)\/?/i', $dir,$atmp);

                $base="";

                foreach ($atmp[0] as $key=>$val)

                {

                    $base=$base.$val;

                    if(!file_exists($base))

                        if (!mkdir($base,$dirmode))

                        {

                                echo "Error: Cannot create ".$base;

                            return -1;

                        }

                }

            }

            else

                if (!is_dir($dir))

                {

                        echo "Error: ".$dir." exists and is not a directory";

                    return -2;

                }

        }



        return 0;



    }

This function creates a directory structure recursively.

If you're on a shared *nix server, a directory created through mkdir() will not be assigned to you, but to the user that your host's server or php process is running under, usually 'nobody', 'apache' or 'httpd'.





In practice, this means that you can create directories, even add files to them, but you can't delete the directory or its contents nor change permissions.





It is therefore advised to create directories through PHP's FTP API. Here's a function I wrote:





<?php


// create directory through FTP connection


function FtpMkdir($path, $newDir) {


   


       $server='ftp.yourserver.com'; // ftp server


       $connection = ftp_connect($server); // connection


   


  


       // login to ftp server


       $user = "me";


       $pass = "password";


       $result = ftp_login($connection, $user, $pass); 





    // check if connection was made


      if ((!$connection) || (!$result)) {


        return false;


        exit();


       } else {


          ftp_chdir($connection, $path); // go to destination dir


        if(ftp_mkdir($connection,$newDir)) { // create directory


            return $newDir;


        } else {


            return false;        


        }


    ftp_close($conn_id); // close connection


    }





}


?>





Hope this comes in handy for someone.

mkdir will create directories with undesired/unexpected owner/group settings in certain circumstandes when SAFE_MODE is on. See the bug report: http://bugs.php.net/bug.php?id=24604

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);

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);


?>
