DateInterval Class

DateInterval Class is simple if you keep it on paper. Amit uses it for class Student in a small OOP file.

Keep DateInterval Class small. Amit should finish class Student in a few lines, not a 40-line dump.

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

Amit ships DateInterval Class in a small OOP file. That is the use case worth saying.

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

Place DateInterval Class next to nearby PHP work — new Student('Asha', 72) is the link.

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

Exam tip

For DateInterval 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();

DateInterval Class — constructor property promotion keeps simple classes short.

Short notes
