Also if you want to pass the code challenge, then you have to read the question again. You are using echo while they ask to use return, also you are missing parts of the text.

<?php

public function getInfo()
  {
    return "A " . $this->common_name . " is an " . $this->flavor . " flavored fish. The world record weight is " . $this->record_weight . ".";
  }

There's an extra dollar sign in your code (record_weight), try this

echo $this->common_name . $this->flavor ."flavored fish." . "The world record weight is " . $this->record_weight;

I'm sure your fatal error goes away if you replace that one line with my answer, but it doesn't solve the challenge yet.
