# mkdir

(PHP 4, PHP 5)

mkdir — Makes directory

### Description

bool mkdir ( string `$pathname` [, int `$mode` [, bool `$recursive` [, resource `$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: `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`

  Default to `FALSE`.

`context`

  > Note: Context support was added with PHP 5.0.0. For a description of contexts, refer to Streams Functions.

### 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 List of Supported Protocols/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);
?>`

### 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.
