issue with getInfo method in child class

I have tried to create the required get-info method adding the extra property from the child but it is not correct. The example in the question has no reference to the species but it is need in the method. Is there an error there

Below is my example implementation of the getInfo() method. As you can see i have concatenated the many different variables to create the same string output as the challenge specifies. Dont forget when classes are extended, the child class has access to all of its public or protected variables or methods of the parent class.

class trout extends Fish {
  public $species;
  function __construct($name, $flavor, $record, $species){
    $this->species = $species;
    parent::__construct($name, $flavor, $record);
  }

  function getInfo(){
     return $this->species." ".$this->common_name.
       " tastes ".$this->flavor.". The record ".$this->species." ".$this->common_name." weighed ".$this->record_weight;
  }
}

Hope this helps!

Hi , I had just finished that course. Ok I believe that you need to declare the parent's construct method as the first thing in the child class's construct method. secondly isnt the $this->record === $this->record_weight; Cheers
