Create a method on fish names getInfo()

Hi all! I am going through this course again as a refresher and although I got through this task the first time, I can't figure out what I'm doing wrong this time around.

What am I missing?

Thanks!

fish.php 
<?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 = $record;
  }
 public function getInfo(){
    return "A" .$name . "is an" .$flavor . "flavored fish." ."The world record weight is" .$record".";
  }

}

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

?>

Hi,

It will pass if you change your getInfo method to:

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

Thanks Hanley!

The only thing that was missing in your example above was the _weight.

This is what worked for me:

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

You may also need to add spaces after the A, before is and after an, etc. But Hanley Chan is exactly right with the variables. You definitely will not pass without his suggestion.

Thanks Ted. It turns out that the spaces weren't needed. I tried that and it didn't pass. Hmmm...In the real world there should be always be spaces in concatenation, right?

No, you misunderstand what I meant. As written, it would echo:

Abassis anexcellentflavored fish.The world record weight is5 pounds.

There are challenges that fail if the proper spacing within the echo is not preserved.

I recently learned you can place the whole thing in double, not single, quotes and do away with the concatenation in this example. PHP processes variables inside double quotes. Variables inside single quotes echo the variable name, not the value.

You do not have to add spaces with your concatenation.
