PHP da OOP da obyektlarni massivlarda saqlash

Faraz qilaylik, bizda User klassi mavjud:

User.php<?php
  class User
  {
    public $name;
    public $age;
    
    public function __construct($name, $age)
    {
      $this->name = $name;
      $this->age = $age;
    }
  }
?>

Klass faylimizni index.php fayliga ulaymiz:

index.php<?php
  require_once 'User.php';
?>

Klassimizning uchta obyektini yaratamiz:

index.php<?php
  $user1 = new User('john', 21);
  $user2 = new User('eric', 22);
  $user3 = new User('kyle', 23);
?>

Endi yaratgan obyektlarimizni $users massiviga yozamiz:

index.php<?php
  $user1 = new User('john', 21);
  $user2 = new User('eric', 22);
  $user3 = new User('kyle', 23);
  
  $users[] = $user1;
  $users[] = $user2;
  $users[] = $user3;
  
  var_dump($users);
?>

O'zgaruvchilardan foydalanmasdan, kodimizni qisqartirishimiz mumkin:

index.php<?php
  $users[] = new User('john', 21);
  $users[] = new User('eric', 22);
  $users[] = new User('kyle', 23);
  
  var_dump($users);
?>

Kodni yana ham qisqartirish mumkin, darhol obyektlar massivini yaratish orqali:

index.php<?php
  $users = [
    new User('john', 21),
    new User('eric', 22),
    new User('kyle', 23)
  ];
  
  var_dump($users);
?>

Endi obyektlar massivimizni tsikl bilan aylantiramiz va obyektlarning xususiyatlarini ekranga chiqaramiz:

index.php<?php
  foreach ($users as $user) {
    echo $user->name . ' ' . $user->age . '<br>';
  }
?>
