It seems like $buffer->readString($thi...ize * $this->dataCount) can also be of type false; however, parameter $str of rtrim() does only seem to accept string, maybe add an additional type check?
                                                                                                                                                                                           (

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

The expression $this->data of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using  ! empty($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.
