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:

Since your code implements the magic getter
_get, this function will be called for any read access on an undefined variable. You can add the@propertyannotation to your class or interface to document the existence of this variable.If the property has read access only, you can use the @property-read annotation instead.
Of course, you may also just have mistyped another name, in which case you should fix the error.
See also the PhpDoc documentation for @property.
