DateTime Class

If you can teach DateTime Class using class Student, you know it. If you only know the heading, you don’t.

For DateTime Class, Apache/Nginx is in play. Don’t blame it until you have traced class Student.

Skip DateTime Class and public everything shows up in a small OOP file.

DateTime Class shows up in a small OOP file. Name class Student, not “a real-world scenario”.

DateTime Class trap — public everything. Amit loses marks for that every viva.

DateTime Class is not a lonely heading. Amit ties it to class Student.

Close DateTime Class with — “If I skip it, class Student goes wrong like this: public everything.”

Exam tip

For DateTime Class: definition + a small OOP file + one failure.

Example

<?php
class User {
  public function __construct(private string $name) {}
  public function hello(): string {
    return "Hello, {$this->name}";
  }
}
echo (new User("Ravi"))->hello();

DateTime Class — constructor property promotion keeps simple classes short.

Short notes

DefDateTime Class — Amit uses it for class Student in a small OOP file.
RuleDateTime Class → new Student('Asha', 72).
RememberDateTime Class + Apache/Nginx (a small OOP file).
UseDateTime Class in a small OOP file (class Student).
TrapDateTime Class — public everything.
ExDateTime Class → class Student.
