Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.
Common duplication problems, and corresponding solutions are:
| 1 | <?php |
||
| 10 | class ErrorReporting extends \Phalcon\Mvc\User\Component |
||
| 11 | { |
||
| 12 | |||
| 13 | View Code Duplication | public function error404() |
|
| 20 | |||
| 21 | View Code Duplication | public function error503() |
|
| 28 | |||
| 29 | } |
||
| 30 |
Methods can only be called on objects. This check looks for methods being called on variables that have been inferred to never be objects.
