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.
