Kuhifadhi Vitu kwenye Arrays katika OOP kwa PHP

Hebu tuchukue tuna darasa User kama hili:

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

Wacha tuunganishe faili lenye darasa letu kwa faili index.php:

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

Wacha tuunde vitu vitatu vya darasa letu:

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

Sasa hebu tuandike vitu tulivyounda kwenye array $users:

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);
?>

Tunaweza kufupisha msimbo wetu, kwa kuondoa viabadilishaji:

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

Unaweza kufupisha msimbo zaidi, kwa kutengeneza array ya vitu moja kwa moja:

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

Sasa hebu tutunge array yetu ya vitu kwa kitanzi na tuonyeshe sifa za vitu kwenye skrini:

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