# mkdir

(PHP 3, 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.

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().

> Note: Mode is ignored on Windows, and became optional in PHP 4.2.0.

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

Example 1. mkdir() example
`<?php mkdir("/path/to/my/dir", 0700); ?>`

Returns `TRUE` on success or `FALSE` on failure.

> Note: As of PHP 5.0.0 mkdir() can also be used with some URL wrappers. Refer to Appendix M for a listing of which wrappers support mkdir().

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

> Note: The recursive parameter was added as of PHP 5.0.0.

> Note: When safe mode is enabled, PHP checks whether the directory in which you are about to operate has the same UID (owner) as the script that is being executed.
