OOP php functions

[Bryce910]

When in OOP I have been watching tutorials and some have functions just written like

 class user
{
public $user;

public function __construct($u)
{
   $this->user = $u;
}

}

 

do I need to type public before the function or is it better practice to just put

 

class user
{
public $user;

function __construct($u)
{
   $this->user = $u;
}

}

 

Thanks!

I believe all functions are public unless nested and you should declare the type of function public or private.

Functions are public without any cast.

 

class A {
    public $user;
    
    public function __construct(){
        $this->user = 'apple';
    }
    
    function getApple(){
        return $this->user;
    }
}

class B {
    public $user;
    
    public function __construct(){
        $a = new A();
        $this->user = 'b' . $a->getApple();
    }
    
    function getApple(){
        return $this->user;
    }
}

$b = new B;
echo $b->getApple();

 

This code would return bapple.

 

If the getApple() method in A was private, B would not be able to access A's getApple() method. However, if A's getApple() method was protected, and class B extends A, then you would be able to access A's getApple() method.

It's better to write public.
