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.
class Trout extends Fish {
public $species;
function __construct($name, $flavor, $record, $species){
parent::__construct($name, $flavor, $record);
$this->species = $species;
}
public function getInfo() {
return "Brook" . $this->common_name . "Tastes" . $this->flavor . " The record" $this->record_weight . $this->species );
}
}
$brook_trout = new Trout("Trout" , "Delicious" , "14 pounds 8 ounces" , "Brook");

If you follow the Markdown Cheatsheet it helps tremendously in attempting to see the code in which you are working. That being said, the following code got me through task 6:
<?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 $species;
public function __construct($name, $flavor, $record, $species) {
parent::__construct($name, $flavor, $record);
$this->species = $species;
}
public function getInfo() {
return $this->species . $this->common_name . "tastes" . $this->flavor . ". " . "The record" . $this->species . $this->name . "weighed" . $this->record_weight . ".";
}
}
$brook_trout = new Trout("Trout", "Delicious", "14 pounds 8 ounces", "Brook");
?>

19,488 PointsThank you for your reply. I forget the echo $brook_trout->getInfo(); and had to move the curly brace to end the function correctly.
`class Trout extends Fish { public $species; function construct($name, $flavor, $record, $species){ parent::construct($name, $flavor, $record);
$this->species = $species; } public function getInfo() { return ( "Brook " . $this->common_name . " Taste " . $this->flavor . " The record Brook Trout weighed " . $this->species . $this->record_weight); } } $brook_trout = new Trout("Trout" , "Delicious" , "14 pounds 8 ounces" , "Brook");
echo $brook_trout->getInfo();`

8,646 PointsLooks like you have some syntax errors.
As for the code not passing, I think it might be that there is an extra parentheses ) after $this->species in your getInfo() function that shouldn't be there.
Also, when concatenating properties, don't forget to add some space in between. For example, you have written:
$this->record_weight . $this->species
It should be:
$this->record_weight . " " . $this->species
EDIT: looks like you got a response already.

19,488 PointsNo I added the space in the string . " string " . Thank you for your reply..
