This class 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.

The return type of return preg_match('/^([0...-F]{1,2})$/', $string); (integer) is incompatible with the return type of the parent method yii\validators\Validator::validateValue of type array|null.
If you return a value from a function or method, it should be a sub-type of the
type that is given by the parent type f.e. an interface, or abstract method.
This is more formally defined by the
Lizkov substitution principle,
and guarantees that classes that depend on the parent type can use any instance
of a child type interchangably. This principle also belongs to the
SOLID principles
for object oriented design.
Our function my_function expects a Post object, and outputs the author
of the post. The base class Post returns a simple string and outputting a
simple string will work just fine. However, the child class BlogPost which
is a sub-type of Post instead decided to return an object, and is
therefore violating the SOLID principles. If a BlogPost were passed to
my_function, PHP would not complain, but ultimately fail when executing the
strtoupper call in its body.
It is not recommended to use PHP's closing tag ?> in files other than templates.
Using a closing tag in PHP files that only contain PHP code is not recommended
as you might accidentally add whitespace after the closing tag which would then
be output by PHP. This can cause severe problems, for example headers cannot be
sent anymore.
A simple precaution is to leave off the closing tag as it is not required, and
it also has no negative effects whatsoever.
