Deprecated Code introduced by Liza
The function yii\base\BaseObject::className() has been deprecated: since 2.0.14. On PHP >=5.5, use `::class` instead. ( Ignorable by Annotation )

If this is a false-positive, you can also ignore this issue in your code via the ignore-deprecated  annotation

63
                'class' => /** @scrutinizer ignore-deprecated */ Client::className(),

This function has been deprecated. The supplier of the function has supplied an explanatory message.

The explanatory message should give you some clue as to whether and when the function will be removed and what other function to use instead.

Bug Best Practice introduced by Anton Tuyakhov
The expression $message->replyMarkup of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

This check marks implicit conversions of arrays to boolean values in a comparison. While in PHP an empty array is considered to be equal (but not identical) to false, this is not always apparent.

Consider making the comparison explicit by using empty(..) or ! empty(...) instead.
