    mkdir

    (PHP 4, PHP 5, PHP 7)

    mkdir — Makes directory

    설명

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

    Attempts to create the directory specified by pathname.

    인수

    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:

    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

    Note: Context 지원은 PHP 5.0.0에서 추가되었습니다. contexts에 관한 자세한 설명은 Streams을 참고하십시오.

    반환값

    성공 시 TRUE를, 실패 시 FALSE를 반환합니다.

    예제

    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...');
    }

    // ...
    ?>

    오류/예외

    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.

    주의

    Note: 안전 모드를 활성화했을 경우, PHP는 작업하려는 디렉토리가 실행중인 스크립트와 같은 UID(owner)를 가지고 있는지 확인합니다.

    참고

    • is_dir() - Tells whether the filename is a directory
    • rmdir() - Removes 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).
