Use array_map to call a method in class with multiple params

class FileUploader {

 /**
 * Upload a single or multiple files to specific target.
 *
 * @param string|array $file
 * @param string $target
 * @return mixed
 */
 public function upload($file, $target)
 {
 if (is_array($file)) {
 return array_map(
 [$this, 'uploadSingle'], 
 $file, 
 array_fill(0, count($file), $target)
 );
 }
 return $this->uploadSingle($file, $target);
 }

 /**
 * Upload a single file to a specific target.
 *
 * @param $file
 * @param $target
 */
 public function uploadSingle($file, $target)
 {
 // Code to handle the file upload.
 }

}
