PHP-de OOP-da Goragly aýratynlyklar
PHP hem-de goragly aýratynlyklary goldaýar.
Olar hem protected üýtgedijisi bilen belledilýär.
Şeýle aýratynlyklar miras alnyp we
ogullarynyň klaslarynda elýeterli bolar.
Goragly aýratynlygy bolan, ýaşy saklaýan ata-klas dörediň:
<?php
class User {
protected $age;
public function setAge($age) {
$this->age = $age;
}
public function getAge() {
return $this->age;
}
}
?>
Oglulyk klasynda bir birlik artdyrýan metod dörediň:
<?php
class Student extends User {
public function incAge() {
$this->age++;
}
}
?>
Aşakdaky kody goragly aýratynlyk arkaly ýazyp görüň:
<?php
class User {
private $name;
public function setName($name) {
$this->name = $name;
}
public function getName() {
return $this->name;
}
}
class Employee extends User {
public function setName($name) {
if (strlen($name) > 0) {
$this->name = $name;
}
}
}
?>
