I do not get the question. Who can help?

Add a getInfo method to your Trout class that returns a string containing the common_name, flavor, record_weight, and species properties. For example, on our brook trout it might return "Brook Trout tastes Delicious. The record Brook Trout weighed 14 pounds 8 ounces."

fish.php
<?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 { 
    public $species;

    function __construct($name, $flavor, $record, $species){
        parent::__construct($name, $flavor, $record);
          $this->species = $species;
    }

  public function getInfo() {
    $output  = $this->species. " " . $this->name . "tastes " . $this->flavor .".";
    $output .= "The record ". $this->species . " " . $this->name;
    $output .= "weighed " . $this->record .".";
      return $output;   
  }
}

$brook_trout = new Trout("Trout", "Delicious", "14 pounds 8 ounces", "Brook");
echo $brook_trout->getInfo();
?>

Hi Sajid, I think the issue is you have used "name" and "record" in your getInfo() method when you should be using "common_name" and "record_weight", try changing your code to the following:

<?php

  public function getInfo() {
    $output  = $this->species. " " . $this->common_name . "tastes " . $this->flavor ."."; //changed name to common_name
    $output .= "The record ". $this->species . " " . $this->common_name;  //changed name to common_name
    $output .= "weighed " . $this->record_weight ."."; //changed record to record_weight
      return $output;   
  }

?>

Hope that helps!!
