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:

explode('.', $file) cannot be passed to array_pop() as the parameter $array expects a reference.

Bug introduced by
The class Automattic\Jetpack\Analyzer\Error does not exist. Did you forget a USE statement, or did you not list all dependencies?

Scrutinizer analyzes your composer.json/composer.lock file if available to determine the classes, and functions that are defined by your dependencies.

It seems like the listed class was neither found in your dependencies, nor was it found in the analyzed files in your repository. If you are using some other form of dependency management, you might want to disable this analysis.

Unused Code introduced by
$ast is not used, you could remove the assignment.

This check looks for variable assignements that are either overwritten by other assignments or where the variable is not used subsequently.

$myVar = 'Value';
$higher = false;

if (rand(1, 6) > 3) {
    $higher = true;
} else {
    $higher = false;
}

Both the $myVar assignment in line 1 and the $higher assignment in line 2 are dead. The first because $myVar is never used and the second because $higher is always overwritten for every possible time line.
