protected function FileStorage::createDirectory

protected FileStorage::createDirectory($directory, $mode = 0777, $is_backwards_recursive = FALSE)

Ensures the requested directory exists and has the right permissions.

For compatibility with open_basedir, the requested directory is created using a recursion logic that is based on the relative directory path/tree: It works from the end of the path recursively back towards the root directory, until an existing parent directory is found. From there, the subdirectories are created.

Parameters

string $directory: The directory path.

int $mode: The mode, permissions, the directory should have.

bool $is_backwards_recursive: Internal use only.

Return value

bool TRUE if the directory exists or has been created, FALSE otherwise.

  // If the parent directory and the requested directory does not exist and
  // could not be created above, walk the requested directory path back up
  // until an existing directory is hit, and from there, recursively create
  // the sub-directories. Only if that recursion succeeds, create the final,
  // originally requested subdirectory.
