Parameters

string $data: A string containing the contents of the file.

int $replace: (optional) The replace behavior when the destination file already exists. Possible values include:

• FileSystemInterface::EXISTS_REPLACE: Replace the existing file. If a managed file with the destination name exists, then its database entry will be updated. If no database entry is found, then a new one will be created.
• FileSystemInterface::EXISTS_RENAME: (default) Append _{incrementing number} until the filename is unique.
• FileSystemInterface::EXISTS_ERROR: Do nothing and return FALSE.

Return value

\Drupal\file\FileInterface|false A file entity, or FALSE on error.

Throws

\Drupal\Core\Entity\EntityStorageException Thrown when there is an error updating the file storage.
