main class has a constructor
How can I set a constructor method for class form?

Answer 1

class Main
{
    private $foo;

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

class Form extends Main
{
    private $bar;

    public function __construct($foo, $bar)
    {
        parent::__construct($foo);
        $this->bar = $bar;
    }
}
