1. 8.9.x core/lib/Drupal/Core/File/FileSystem.php \Drupal\Core\File\FileSystem::chmod()
2. 10 core/lib/Drupal/Core/File/FileSystem.php \Drupal\Core\File\FileSystem::chmod()
3. 11.x core/lib/Drupal/Core/File/FileSystem.php \Drupal\Core\File\FileSystem::chmod()

Sets the permissions on a file or directory.

This function will use the file_chmod_directory and file_chmod_file settings for the default modes for directories and uploaded/generated files. By default these will give everyone read access so that users accessing the files with a user account without the webserver group (e.g. via FTP) can read these files, and give group write permissions so webserver group members (e.g. a vhost account) can alter files uploaded and owned by the webserver.

PHP's chmod does not support stream wrappers so we use our wrapper implementation which interfaces with chmod() by default. Contrib wrappers may override this behavior in their implementations as needed.

Parameters

string $uri: A string containing a URI file, or directory path.

int $mode: Integer value for the permissions. Consult PHP chmod() documentation for more information.

Return value

bool TRUE for success, FALSE in the event of an error.
