8 file.module file_save_data($data, $destination = NULL, $replace = FILE_EXISTS_RENAME)

Saves a file to the specified destination and creates a database entry.

Parameters

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

$destination: A string containing the destination URI. This must be a stream wrapper URI. If no value is provided, a randomized name will be generated and the file will be saved using Drupal's default files scheme, usually "public://".

$replace: Replace behavior when the destination file already exists:

  • FILE_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.
  • FILE_EXISTS_RENAME - Append _{incrementing number} until the filename is unique.
  • FILE_EXISTS_ERROR - Do nothing and return FALSE.

Return value

A file object, or FALSE on error.
