Adding property to a child class in php

In a code challenge I was told to:

"Add a property named species to the Trout class."

I did this:

<?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 {
  function __construct($name, $flavor, $record) {
    parent::__construct($name, $flavor, $record);
    public $species;
  }
}

?>

and it was wrong. Any ideas?

Properties must be declared in the body of your class and not within a function. By declaring a variable inside a function, you limit its scope to just that function.

<?php

class Trout extends Fish {

  // Declare a class wide property
   public $species;

  function __construct($name, $flavor, $record, $species) {
    parent::__construct($name, $flavor, $record);   
    // Set the value of property
    $this->species = species;
  }
}

Never mind. I figured it out. I had added the property inside the construct method. I put it outside and it worked.
