Kuhifadhi Vitu kwenye Arrays katika OOP kwa PHP
Hebu tuchukue tuna darasa User kama hili:
<?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:
<?php
require_once 'User.php';
?>
Wacha tuunde vitu vitatu vya darasa letu:
<?php
$user1 = new User('john', 21);
$user2 = new User('eric', 22);
$user3 = new User('kyle', 23);
?>
Sasa hebu tuandike vitu tulivyounda
kwenye array $users:
<?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:
<?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:
<?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:
<?php
foreach ($users as $user) {
echo $user->name . ' ' . $user->age . '<br>';
}
?>
Tengeneza darasa City, ambamo litakuwa na
sifa zifuatazo: name, population.
Unda vitu 5 vya darasa City,
jaza kwa data na uandike kwenye array.
Tunga array uliyoiumba na miji kwa kitanzi na uonyeshe miji na idadi ya wakazi wake kwenye skrini.
