OOP PHP Basics

<?php

public function __construct($name, $flavor, $record, $species){
  parent::__construct($name, $flavor, $record);
    $this->species = $species;
}
   public function getInfo(){
    $this->species . " "
    $this->common_name . " tastes "
    $this->flavor . ". The record " 
    $this->species . " "
    $this->common_name . " weighed "
    $this->record_weight;
  }
}

$brook_trout = new Trout("Trout", "Delicious", "14 pounds 8 ounces", "Brook");

?>

Need to return via public function getinfo "Brook Trout tastes delicious. The record Brook Trout weighed 14 pounds 8 ounces."

What am I doing wrong...?

First, you do not define the attribute public $species;.

Second, you do not define a class anywhere. If I remember right, you need a class Fish followed by a class Trout extends Fish;.

Third, your public function getInfo() has all sorts of issues. You actually do not do anything with the method (a function inside a class) has to have a return. I have been successful with something like this:

<?php
// fill in proper code here

public function getInfo() {
    return "$this->common_name $this->species is a $this->flavor tasting fish.  The record weight is $this->record.";
}

Using double quotes allows the variable to be parsed inside the double quotes.

You could do something like you propose, but you have to assign it to a variable and then return the variable.
