  1. 8.9.x core/includes/file.inc \drupal_mkdir()

Creates a directory, optionally creating missing components in the path to the directory.

When PHP's mkdir() creates a directory, the requested mode is affected by the process's umask. This function overrides the umask and sets the mode explicitly for all directory components created.

Parameters

$uri: A URI or pathname.

$mode: Mode given to created directories. Defaults to the directory mode configured in the Drupal installation. It must have a leading zero.

$recursive: Create directories recursively, defaults to FALSE. Cannot work with a mode which denies writing or execution to the owner of the process.

$context: Refer to http://php.net/manual/ref.stream.php

Return value

Boolean TRUE on success, or FALSE on failure.
