2,843 PointsCreating methods
I feel a little sheepish, It's been like 10 minutes since my last question, but... Here's the request: 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."
And here's my code inside of the class: ''' function getInfo() { echo "A $name is an $flavor flavored fish. The world record weight is $record ."; } '''
Any wisdom to impart?

What you have is correct (to a point). When you surround a phrase in double-quotes ("), you can inject any variable and it echos out the value inside of the variable. However, since this is a class method, you need to use the 'this->' in front of all of the properties in order to gain access to the classes properties. Just add the $this-> in front of your variables inside your return phrase and you'll be fine.
Cheers!

3,537 PointsIn your getInfo method, similar to the example in the video, rather than echo, use return; you'll use echo below in its own statement to process the method with the properties from $bass.
Also, your concatenation is a bit off; make sure you know where to place the spaces and periods. Your line should be reading similar to the following:
public function getInfo(){
return "A " . $this->common_name . " is an " . $this->flavor . " flavored fish. The world record weight is " . $this->record_weight . ".";
}
Your echo statement then comes outside the class, just below your definition of $bass:
echo $bass->getInfo();

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

echo 'A ' . $name . ' is an ' . $flavor // and so on

11,321 PointsI am having a similar problem. I tried to follow the suggestions here but I'm still stuck. Here is what I have
<?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(){ echo "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");
?>

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