What is the difference between $ this-> render () and $ this-> redirect ()

Question

I'm new to the Yii framework, and I would like to know the difference between $this->render() and $this->redirect() .
Both can be used to retrieve a given page.

Answer 1

They seem to be doing very different things:

• ->redirect($url, ...)
  redirect redirects an HTTP page. Does not display the page directly.

• ->render($view, ...)
  render displays a named view. Does not complete the current PHP request.

Answer 2

After redirecting, the browser will request another page, which will have its own call to render (). With redirects, you will see a change in the URL in the address bar and another page. Unless, of course, you are redirected to the page on which you were already.

Answer 3

-> Render ('$' view, ...)

this is best used when you want to display the same page, as this save action means that it cannot change the browser url.

-> redirect ('$ relative_url', ..)

this is best used to display another page because it changes the url as well as the action.
