using save to update in laravel code example
Example 1: eloquent update row response
DB::table('users')
->where('id', 1)
->update(['votes' => 1]);
Example 2: laravel difference between fill and update
<?php$user = User::find(1);
// This will update immediately
$user->update(['first_name' => 'Braj', 'last_name' => 'Mohan']);
// This will not update underlying data store immediately
$user->fill(['first_name' => 'Fred', 'last_name' => 'Avad']);
// At this point user object is still only in memory with updated values but actual update query is not performed.
// so we can have more logic here
$user->is_active = true;
// Then finally we can save it.
$user->save(); // This will also make user active
