Should this not echo something to the screen?

Just finished the Properties and Methods Stage of the brilliant PHP Object Oriented course.

After finishing the stage I decided to have a go myself.

First by putting it into localhost on XAMPP and then here on my server. Warning: link may not work some time after question is answered, :)

Here's the code

    <?php
        class Fish {

              //properties
              public $common_name;
              public $flavor;
              public $record_weight;

              //constructor method - 3 parameters
              function __construct($name, $flavor, $record){
                //assigned properties with the 3 parameters
                $this->common_name = $name;
                $this->flavor = $flavor;
                $this->record_weight = $record;


              }
              //A method that returns a string wuth property values
                function getInfo() {
                return "A " . $this->common_name . " is an " . $this->flavor . " flavoured fish. The world record weight is " . $this->record_weight . ".";
            }
        }

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

Shouldn't I see something be echoed to the screen below the word testing? Even if I just use the return keyword to try and display the sentence?

Thanks. :)

No, you will not see anything because you are passing echo the entire object itself. If you want it to print something, you would need to pass echo something like the results of your object's getInfo method.

Hope this helps!

Jake is correct, so plus one. var_dump($bass) instead of echo to see your object on the screen.

Thanks, I figured out how to get the sentence displayed to the screen with the Object operator based on this and info from another thread. :)

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

?>
