Challenge Task 6 of 7
I have no idea what to do :(
<?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 = $species;
}
public getInfo() {
return = "$this->common_name tastes $this->flavor. " . "The record $this->record weighed $this->species.";
}
}
$brook_trout = new Trout("Trout", "Delicious", "14 pounds 8 ounces", "Brook");
$brook_trout = new getInfo();
?>

Courses Plus Student 17,967 PointsYour primary problem is that you do not use all of the variables. Also, if you use double quotes you can place the variables inside the quotes without adding concatenation because PHP evaluates the variable before the echo when using double quotes. Singles quotes will echo the variable name, not the value, so you would have to concatenate. This should pass:
<?php
public function getInfo() {
return "$this->species $this->common_name tastes $this->flavor. The record weight $this->species $this->common_name is $this->record_weight.";

36,305 PointsI got it to work but can someone give me some help understanding this a bit better.
Why do we need to set
$this->common_name
and
$this->record_weight
?
Haven't we assigned those values to $name
and $record
?
