What Changes I have to do in this code

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

$brook_trout = new Trout("Trout", "Delicious", "14 pounds 8 ounces", "Brook");
echo $trout->getInfo();
?>
