Add parameter in __contruct dont work.

Add a fourth parameter, $species, to the Trout constructor. Set the species property to that parameter within the constructor.

fish.php
<?php

class Fish
{
    public $common_name;
    public $flavor;
    public $record_weight;

    function __construct($name, $flavor, $record){
        $this->common_name = $name;
        $this->flavor = $flavor;
        $this->record_weight = $record;
    }

    public function getInfo() {
        $output  = "The {$this->common_name} is an awesome fish. ";
        $output .= "It is very {$this->flavor} when eaten. ";
        $output .= "Currently the world record {$this->common_name} weighed {$this->record_weight}.";
        return $output;
    }
}

class Trout extends Fish{
  public $species;
  function __construct($name, $flavor, $record, $species){
    parent::__construct($name,  $flavor, $record);
  }

}

?>

In the trout class constructor, after passing the first three parameters to the parent class be sure to set the $species member variable:

this->$species = $species;
