Update multiple records using Eloquent

How to set every row to the same value with Laravel's Eloquent/Fluent?

Example:

id    |   data         |  confirmed 

1     | someData |      0 

2     | someData |      1 

3     | someData |      0

There is a way to do this with fluent:

$affected = DB::table('table')->update(array('confirmed' => 1));

or even better

$affected = DB::table('table')->where('confirmed', '=', 0)->update(array('confirmed' => 1));

Update multiple records using Eloquent:

How can I update multiple rows with a single query like:

$update = mysql_query("update item_table set colour = 'black' where item_type_id = 1");

Solution:

ItemTable::where('item_type_id', '=', 1) ->update(['colour' => 'black']);

id    |   data         |  confirmed 

1     | someData |      0 

2     | someData |      1 

3     | someData |      0
