What did i do wrong? (PHP)

I'm on last part of the last task on this section, The code looks completely correct to me. What am I doing wrong?

Question: Add a getInfo method to your Trout class that returns a string containing the common_name, flavor, record_weight, and species properties. For example, on our brook trout it might return "Brook Trout tastes Delicious. The record Brook Trout weighed 14 pounds 8 ounces."

Code:

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() {
        return $this->species . " " . $this->name . " tastes " . $this->flavor . ". The record " . $this->species . " " . $this->name . "weighed " . $this->record;
    }
}

$brook_trout = new Trout("Trout", "Delicious", "14 pounds 8 ounces", "Brook");

?>

Hi Devin,

You have a few minor errors in your getInfo function which are as follows:

  1. $this->name isn't a valid property, instead you should be requesting $this->common_name
  2. You don't have a space before the word weighed
  3. $this->record isn't a valid property, instead you should be requesting $this->record_weight

See the below.

<?php

class Trout extends Fish {
  public $species;

  function __construct($name, $flavor, $record, $species) {
    parent::__construct($name, $flavor, $record);
    $this->species = $species;
  }

  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");

?>

Happy coding!
