Trouble calling object to output function

<?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;
  }

  function getInfo() {
    return "A " $common_name " is an " $flavor " flavored fish. The world record weight is " $record_weight"." 
  }
}
$bass = new Fish("Largemouth Bass", "Excellent", "22 pounds 5 ounces");
$bass->getInfo();
?>

What am I missing in order to get this quiz question right? Thanks.

The problem is in the getInfo method.

  1. You need to use a period to concatenate the different variables and sections of the string together.
  2. You need a semicolon at the end of the string.
  3. You are not referencing the variables correctly as you used "$this" to set the variables, you also need to use $this to recall the variables ($this->$common_name, etc.)
<?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;
  }

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

$bass = new Fish("Largemouth Bass", "Excellent", "22 pounds 5 ounces");
