Object-Oriented PHP Basics - Mid-course challenge

Where did I go wrong? This is Challenge task 5 of 5.

Create a method on Fish named getInfo that takes no parameters and returns a string that includes the common_name, flavor, and record_weight for the fish. When called on $bass, getInfo might return "A Largemouth Bass is an Excellent flavored fish. The world record weight is 22 pounds 5 ounces."

<?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() {
    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");

echo $bass->getInfo();

?>

I'm pretty sure you messed up the concatenation near the end of the getInfo method.

    "record weight is ." $this->record_weight;

you put the period inside the quotation mark instead of outside of it. Also, I think you need to add on the period to the end of the sentence.

 "record weight is " . $this->record_weight . "." ;

This worked for me

<?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() {
    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');
echo $bass->getInfo();
?>

There was an other mistake in your code. In your getInfo method, you wrote "$this->$flavor" instead of "$this->flavor".
