Not working in php OOP. I just can not find the problem

The getInfo method wont work for me with the new object.

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);
          $this->species = $species;
    }

  public function getInfo() {
    $output  = $this->species. " " . $this->name . "tastes " . $this->flavor .".";
    $output .= "The record ". $this->species . " " . $this->name;
    $output .= "weighed " . $this->record .".";
      return $output;   
  }
}

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

Hi Sajid Latif,

You have a very simple typo which is instead of calling the getInfo method on $brook_trout you're calling it on $fish, simply change that and your code should work.

echo $brook_trout->getInfo();

Happy coding!
