Le problème vient de votre classe d'élève.

Chaque fois que l'attribut takeLesson 时，您都会覆盖 data est appelé

Cela peut donc être résolu en utilisant un tableau pour les stocker Comme ça

class Student
{
    private $data = [];

    public function takeLesson($lessonName)
    {   
        $lesson = new Lesson;
        $lesson = $lesson->getDetail($lessonName);

        
        $dataLesson = $lesson['name'];        
        
       
        $totalDuration = array();
        $days = array();
        foreach($lesson['schedule'] as $schedule){
            $totalDuration[] = $schedule['duration'];
            $days[] = $schedule['day'];
        }

        $day = implode(", ", $days);

        $totalDuration = array_sum($totalDuration);

        $building = new Room;
        $building = $building->getBuilding($lesson['room']);
       
        $this->data[] = [
            "Name" => "YOUR_NAME",
            "Lesson" => $dataLesson,
            "Total duration"=> $totalDuration,
            "Room" => $lesson['room'],
            "Lecturer" => $lesson['lecturer'],
            "Day" => $day,
            "Building" => $building           
            ];
        
    }

    public function getLessonSummary()
    {
        $dataArray = $this->data;
        list() = multiple();

        foreach($dataArray as $data) {
            foreach ($data as $key => $value) {
                if("array" == gettype($value)){
                    $value= json_encode($value);
                }
                echo "$key : $value\n";
                echo '
';
            }      
            echo '
';
        }
    }
}
