How to fix   Duplicated Code   

Duplicated Code

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:

Bug introduced by
The class Memcached does not exist. Did you forget a USE statement, or did you not list all dependencies?

This error could be the result of:

1. Missing dependencies

PHP Analyzer uses your composer.json file (if available) to determine the dependencies of your project and to determine all the available classes and functions. It expects the composer.json to be in the root folder of your repository.

Are you sure this class is defined by one of your dependencies, or did you maybe not list a dependency in either the require or require-dev section?

2. Missing use statement

PHP does not complain about undefined classes in ìnstanceof checks. For example, the following PHP code will work perfectly fine:

if ($x instanceof DoesNotExist) {
    // Do something.
}

If you have not tested against this specific condition, such errors might go unnoticed.

Unused Code Comprehensibility introduced by
53% of this comment could be valid code. Did you maybe forget this after debugging?

Sometimes obsolete code just ends up commented out instead of removed. In this case it is better to remove the code once you have checked you do not need it.

The code might also have been commented out for debugging purposes. In this case it is vital that someone uncomments it again or your project may behave in very unexpected ways in production.

This check looks for comments that seem to be mostly valid code and reports them.

Duplication introduced by
This method seems to be duplicated in your project.

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.

You can also find more detailed suggestions in the “Code” section of your repository.
