[Solved] PHP OOP basics mid course test confusion.

Working on the PHP Object Oriented Programming course and am at the mid-way test and on the final task of the test but I am getting lost on some logic when trying to print out the sentence.

See my getInfo return. What am I missing? I have an PHP IDE which says it's a valid return statement.

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 weight is". $this->$record_weight;

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

echo $bass->getInfo();

hi Stephen

the problem is when you refer to $this within that class there is no need to access the classes property with the $ infront of the property name. the error is in your call to the getInfo() method. Instead of calling $this->$common_name call it like this $this->common_name. so your code should look like this.

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 weight is". $this->record_weight;

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

echo $bass->getInfo();
