PHP Object-Oriented PHP Basics (Retired) Inheritance, Interfaces, and Exceptions Final Challenge

Stating my answer is wrong but don't know why

So the question is: "Create a constructor for the Trout class with three parameters in order: $name, $flavor, and $record. Call the parent constructor inside the new constructor."

and I created

class Trout extends Fish { function construct($name,$flavor,$record){ parent::construct($name,$flavor,$record); } }

what have I missed?

You missed the double underscore after parent::

Should be parent::__construct($name,$flavor,$record);

      function __construct($name, $flavor, $record){
        Fish::__construct($name,$flavor,$record);
      }
    }

__construct() is a magic method used by php that tells the object being created how it should be formed. Magic methods are called by php implicitly. So when you create a class Car, you can optionally pass in values to the object being created so that object will have those values. http://php.net/manual/en/language.oop5.magic.php

<?php

class Car {

public $wheels;

public function __construct($numberOfWheels){
$this->wheels = $numberOfWheels;
}
}

$car = new Car(4);

Make sure that you are closing both sections of the code too. 

class Trout extends Fish {
  function __construct($name, $flavor, $record) {
    Fish::__construct($name, $flavor, $record);
  }
}
