PHP Object-Oriented PHP Basics (Retired) Properties and Methods Mid-Course Challenge

Does the computer want a blank constructor?

I know how to do this in real life. I can't get any feedback as to what the computer actually wants. Do I need to declare my properties? Should I set them to public, private or protected? Should a constructor be blank? Or should I use it to give properties values ($this->property = $property)? I can't figure out why what I'm do is wrong. It's something a human would recognize, but not the machine.

fish.php 
<?php

class Fish {
  private $name;
  private $flavor;
  private $record;

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

?>

Hi James,

Like with any other PHP code we write for classes such as methods we need to prefix the constructor with the function keyword, a couple of other minor problems is your class properties name and record should be common_name and record_weight.

<?php

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

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

Happy coding!
