mkdir

(PHP 4, PHP 5, PHP 7)

mkdir — Makes directory

Descrierea

mkdir ( string $pathname , int $mode = 0777 , bool $recursive = false , resource $context = ? ) : bool

Attempts to create the directory specified by pathname.

Parametri

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.

Notă:
mode is 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

Notă: Susținrea contextelor a fost adăugată începând cu PHP 5.0.0. Pentru o descriere a contextelor, referiți-vă la Streams.

Valorile întoarse

Întoarce valoarea true în cazul succesului sau false în cazul eșecului.

Exemple

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, 0777, true)) {
    die('Failed to create folders...');
}

// ...
?>

Erori/Excepții

Emits an E_WARNING level error if the directory already exists.

Emits an E_WARNING level error if the relevant permissions prevent creating the directory.

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);
?>

When creating a file using mkdir() the default root will be the DocumentRoot (in XAMPP) itself. 

C:\xampp\htdocs\project/includes/something.php

If you use mkdir("myfile") in something.php, instead of creating the folder in includes, php will create it in the project folder

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, 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!

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).
