mysql - Retrieve last inserted Id. Laravel -

i want retrieve last inserted id table students , pass view. don't know how to? have used following code inserting data inside table.

public function store(request $request)     {          $input=request::all();          student::create($input);         $students=student::all();         $m_fees=m_fees::all();         return view('students.fees',compact('students','m_fees'));      }  

can me?

actually figured out! store model in variable like:

  $student= student::create($input);         $students=student::all();         $insertedid= $student->id;         return $insertedid; 

it works pretty well!
