[php][laravel] what is the difference between Redirect::to() and Redirect::intended() ?

Redirect::to() or $redirect->to() will simply redirect the user to the page as the argument in the method.

Redirect::to('auth.login'); /* Redirect the user to the login page */ .

Redirect::intended() or $redirect->intended() will redirect the user to where they were intended to go. For example, I tried to view a private page, but I was redirected to login. After I logged in, i'd be redirected to my intended location (the page I was trying to access). You can also add to the intended method, such as another page incase the page the user was intending to go to is no longer available.

Redirect::intended('articles.index'); /* Try and redirect them to where they were going, if it fails, redirect them to articles homepage */
