Laravel - Query Builder - Increment And Decrement

The query builder also provides convenient methods for incrementing or decrementing the value of a given column. Both of these methods accept at least one argument: the column to modify. A second argument may be provided to specify the amount by which the column should be incremented or decremented:

    DB::table('users')->increment('votes', 5);
    DB::table('users')->decrement('votes', 5);

You may also specify additional columns to update during the operation:

    DB::table('users')->increment('votes', 1, ['name' => 'John']);
