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 Stream Functions.
Return Values
Returns TRUE on success or FALSE on failure.

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.
