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 |
||
8 | class Post extends ActiveRecordModelExtender |
||
9 | { |
||
10 | |||

||
13 | */ |
||
14 | protected $tableName = "ramverk1_posts"; |

16 | /** |
||
17 | * Columns in the table. |
||
18 | * |

This check looks for PHPDoc comments describing methods or function parameters that do not exist on the corresponding method or function. It has, however, found a similar but not annotated parameter which might be a good fit.
Consider the following example. The parameter
$ireland
is not defined by the methodfinale(...)
.The most likely cause is that the parameter was changed, but the annotation was not.
