Class

DrupalDefaultEntityController

Default implementation of DrupalEntityControllerInterface.

Code

protected function filterId($id) {

  // ctype_digit() is used here instead of a strict comparison as sometimes
  // the id is passed as a string containing '0' which may represent a bug
  // elsewhere but would fail with a strict comparison.
  return is_numeric($id) && $id == (int) $id && ctype_digit((string) $id);
