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:

$this->getFileDir()can contain request data and is used in file manipulation context(s) leading to a potential security vulnerability.General Strategies to prevent injection
In general, it is advisable to prevent any user-data to reach this point. This can be done by white-listing certain values:
if ( ! in_array($value, array('this-is-allowed', 'and-this-too'), true)) { throw new \InvalidArgumentException('This input is not allowed.'); }For numeric data, we recommend to explicitly cast the data:
