* Defaults to NULL.
* @param int $replace
* (optional) The replace behavior when the destination file already exists.
* Possible values include:
* - FILE_EXISTS_REPLACE: Replace the existing file.
* - FILE_EXISTS_RENAME: (default) Append _{incrementing number} until the
* filename is unique.
* - FILE_EXISTS_ERROR: Do nothing and return FALSE.
*
* @return array|\Drupal\file\FileInterface|null|false
* An array of file entities or a single file entity if $delta != NULL. Each
* array element contains the file entity if the upload succeeded or FALSE if
* there was an error. Function returns NULL if no file was uploaded.
*
* @deprecated in Drupal 8.4.x, will be removed before Drupal 9.0.0.
* For backwards compatibility use core file upload widgets in forms.
*
* @internal
* This function wraps file_save_upload() to allow correct error handling in
* forms.
*
* @todo Revisit after https://www.drupal.org/node/2244513.
