Create a child class of the Fish class named Trout.

class Trout extends Fish

I wish I knew why this isn't right?

<?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 }

?>

Sorry for the delay, you have your Trout class wrapped in the Fish class, it should look like the below.

<?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 {
    /* ... */
}

?>

Hi Anika,

Does the Fish class exist before the Trout class? Are they in the same file?

Yeah... I"m just doing a challenge:

<?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;
}

}

?>
