php foreach loop using the mvc model guidance for a begginer [closed]

New to the PHP and the MVC model structure so please be gentle as I try to figure this out as I know I making some mistakes but cannot figure out where. I have been trying to search and experiment with other submitted questions and YouTube with no luck.

Trying to query my database table personal_best and return a looped list <li></li> for the columns pb_species, pb_weight_lbs and pb_weight_oz for a specific user and display them to my webpage.

I have my model class (class PBInfo extends Dbh)
controller class (class PBInfoContr extends PBInfo)
view class (class PersonalBestInfoView extends PBInfo).

In my model class I have the following:

protected function getPBRecords($userId) {
        $stmt = $this->connect()->prepare('SELECT * FROM personal_best WHERE users_id = ?;');
        $stmt->execute(array($userId));

        while($row = $stmt->fetchAll(PDO::FETCH_ASSOC)) {
            $results [] = $row;
        }
        
        return $results;
    }

In my controller class I have the following:

public function displayPBRecords() {
        $row = $this->getPBRecords();
        $this->row = $pbRecords;
    }

In my view class I have the following code:

public function fetchPBRecords($userId) {
        $personalBestInfo = $this->getPBRecords($userId);
        
        foreach ($pbRecords as $data) {
        echo "<li>".$data['pb_species']."<br>".$data['pb_weight_lbs']." lbs ".$data['pb_weight_oz']." oz</li>";
        }
    }

In the webpage to display the looped data I have:

<?php $personalBestRecord->fetchPBRecords($_SESSION['userid'])?>

I get the following 2 error messages when I try to run the page:

1. Undefined variable $pbRecords in my view class.
2. foreach() argument must be of type array|object null given in my view class.

Any suggestions would be appreciated and thanks in advance.
