mkdir

(PHP 4, PHP 5, PHP 7, PHP 8)

mkdir — Makes directory

Опис

mkdir(
    string $directory,
    int $permissions = 0777,
    bool $recursive = false,
    ?resource $context = null
): bool

Attempts to create the directory specified by directory.

Параметри

directory

The directory path.

Підказка

URL як назву файлу можна використовувати з цією функцією, якщо ввімкнені обгортки fopen. Докладніше про те, як вказати назву файлу: fopen(). На сторінці Підтримувані протоколи та обгортки є посилання на інформацію про можливості різних обгорток, примітки щодо їхнього використання, інформацію про будь-які попередньо визначені цими обгортками змінні.

permissions

The permissions are 0777 by default, which means the widest possible access. For more information on permissions, read the details on the chmod() page.

Зауваження:
permissions is ignored on Windows.

Note that you probably want to specify the permissions as an octal number, which means it should have a leading zero. The permissions is also modified by the current umask, which you can change using umask().

recursive

If true, then any parent directories to the directory specified will also be created, with the same permissions.

context

resource контекст потоку.

Значення, що повертаються

Повертає true у разі успіху або false в разі помилки.

Зауваження:
If the directory to be created already exists, that is considered an error and false will still be returned. Use is_dir() or file_exists() to check if the directory already exists before trying to create it.

Помилки/виключення

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.

Приклади

Приклад #1 mkdir() example

<?php
mkdir("/path/to/my/dir", 0700);
?>

Приклад #2 mkdir() using the recursive parameter

<?php
// Desired directory 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 directories...');
}

// ...
?>

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).
