How to call one method to another?

Question

PHP

Guys, tell me, I don’t know where to look anymore. I need a method inside a class to be able to work inside another method. I simplified the example for understanding. Writes that the function is not declared.

class myPage
{
  private function hellow_world()
  {
    return 'hellow_world';
  }
  
  public function createPage()
  {
    return hellow_world();	
  }
}

$page = new myPage();
echo $page->createPage();

Answer 1

return $this->hellow_world()
Hello is written without w ;)
