WhereNotIn ()

You can use the whereNotIn method to simply filter the collection by keys that are not included in a given array. It is basically the opposite of whereIn. In addition, this method uses loose comparison = = when matching values.

Let's filter $collection, where user_id is neither 1 nor 2.

$collection- > whereNotIn ('user_id', [1,2])

The above statement will return only the last item in $collection. The first parameter is the key and the second parameter is the value array. If it is eloquent, the first parameter will be the name of the column and the second parameter will be an array of values.
