Can't figure out whats wrong with this. Create a new trout object.

Feel like I've tried everything but keep coming back to this. Is this not a new trout 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){
  $this->species = $species;
  parent::__construct($name, $flavor, $record);
  $brook_trout = new Trout("Trout", "Delicious", "14 pounds 8 ounces", "Brook");
  }

}
?>

Inside your Trout class you basically did an infinite recursion by putting the following call into the Trout's __constructor method.

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

Which means when you create new Trout, it creates another one, which creates another one into infinity... You are supposed to put that command after the Trout class, like this:

<?php
class Trout extends Fish{
  public $species;
  function __construct($name, $flavor, $record, $species){
  $this->species = $species;
  parent::__construct($name, $flavor, $record);

  }

}

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

?>
