In Laravel you can use the with() method to pass data to a view for example.

But there are different ways of this with() method as for how the passed parameters are treated by the system in the view they've been passed to:

Case 1: return redirect, session variable

In the function:  return redirect ('sample/page')->with('myMessage', ‘This is my message’); 

In the view:  {{ session('myMessage') }} 

Case 2: return view, variable

In the function:  return view ('sample/page')->with('myMessage', ‘This is my message’); 

In the view:  {{ $myMessage }}
