Использование $ this внутри subobject

Question

Я хочу передать $ this в под-объекты, которые я создаю на construct Однако, когда я дам, я получаю флаг **RECURSION**.

Answer 1

при создании нового класса, который расширяет другой класс, вам не нужно, чтобы передать что-нибудь конструктору, он будет автоматически доступен в подклассе до тех пор, как эти методы/свойства являются открытыми или защищенными. Если они являются частными, вы не можете использовать их в подклассе. Если вы хотите использовать защищенные/общедоступные свойства или методы из родительского класса в вашем подклассе, используйте их так, как если бы вы были в родительском классе.

class parent{ 
protected $foo = 'foobar'; 
protected function get_foo(){ 
    return $this->foo; 
} 
} 

class subclass extends parent{ 

protected $bar; 
public function __construct(){ 
    $this->bar = $this->get_foo(); 
} 
public function get_bar(){ 
    return $this->bar; 
} 
} 


$baz = new bar; 
echo $baz->get_bar(); 

// outputs 'foobar'
