PHP Constructor Code Challenge

In the new constructor method, assign each of the properties on the Fish class with its corresponding parameter variable. I've looked at this every way I can and I just cannot understand it. Can anyone help me with the answer and explain why please? Thanks! Here's my code so far:

<?php

class Fish
{
    public $common_name;
    public $flavor;
    public $record_weight;

    function __construct($name, $flavor, $record){
    $this->name = $name;
    $this->flavor = $flavor;
    $this->record = $record;
    }
}
?>
fish.php 
<?php

class Fish
{
    public $common_name;
    public $flavor;
    public $record_weight;

    function __construct($name, $flavor, $record){
    $common_name->name = $common_name;
    $this->flavor = $flavor;
    $this->record = $record;
    }
}
?>

Hey Andrew.

What you need to do is use the $this to assign the specific instances of the variables in the construct to the variables already declared the class.

<?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;
    }
}
?>

Hampton explains more clearly than I can in this video starting at about the 1:05 mark.

Hope this helps! Keep Coding! :)

Weird, I tried that code earlier and I got it wrong, just tried it again and I got it right. Strange. Thanks so much for the help!

There was probably a small typo somewhere in the code you first tried.
