protected function FileStorage::createDirectory in Drupal 8

Same name and namespace in other branches

1. 9 core/lib/Drupal/Component/PhpStorage/FileStorage.php \Drupal\Component\PhpStorage\FileStorage::createDirectory()

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.

Return value

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