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 $name;
      public $flavor;
      public $record;
      public $species;

    function __construct($name, $flavor, $record, $species){
      parent::__construct($name, $flavor, $record);

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

        return $output;
}
$brook_trout = new Trout("Trout", "Delicious", "14 pounds 8 ounces", "Brook");
$brook = new getInfo();
?>

I see one definite problem with your code: You create a $brook_trout object then try to use a $brook object.

I also don't think you need to repeat all the public variables from the parent class, but may be wrong about that.

The problem is with the get info method inside Trout Class, not with the object. I mean, i fixed the $book_trout and it is still not working.

I have not seen the concatenation the way you have done it with any {} in that line. 

$output = $this->common_name . " tastes " . $this->

I am not sure why you passed earlier with curly braces in the Fish getInfo().
