This is my result, but this is not my expectation
Name : YOUR_NAME Lesson : Algorithm and Programming Total duration : 3 Room : A17 Lecturer : Ikhsan Permadi Day : Monday, Thursday Building : South Block Name : YOUR_NAME Lesson : Data Structure 2 Total duration : 2 Room : B10 Lecturer : Faisal Sulhan Day : Wednesday Building : North Block Name : YOUR_NAME Lesson : Data Structure 2 Total duration : 2 Room : B10 Lecturer : Faisal Sulhan Day : Wednesday Building : North Block
I can't create an array value in a class, how can I do that, this is my expected output
// Output // ================================================ // Name: YOUR_NAME // Lesson: Algorithm and Programming // Total duration: 3 SKS // Room: A17 // Lecturer: Ikhsan Permadi // Day: Monday, Thursday // Building: South Block // Name: YOUR_NAME // Lesson: Artificial Intelligence, Data Structure 2 // Total duration: 5 SKS // Room: B12, B10 // Lecturer: Ikhsan Permadi, Faisal Sulhan // Day: Thursday, Wednesday // Building: North Block // Name: YOUR_NAME // Lesson: Algorithm and Programming, Advanced Database, Artificial Intelligence, Data Structure 2 // Total duration: 12 SKS // Room: A17, B12, B10 // Lecturer: Ikhsan Permadi, Faisal Sulhan // Day: Monday, Thursday, Tuesday, Wednesday // Building: South Block, North Block

The problem is with your student class.
Each time you call
takeLessonyou are overwriting thedatapropertySo it can be solved by using an array to store them like this
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 '
'; } } }
