Answer 1

Yes you can, but that increases code coupling and makes testing harder.
I’d suggest creating it outside the class and pass it as an argument (it is called Dependency Injection).

class Foo
{
}

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

$foo = new Foo();
$bar = new Bar($foo);
