Laravel 5 Collections: Filtering a Collection Based On Key Presence Using Strict Comparison Operators With whereNotInStrict

The whereNotInStrict method will return all of the items in a collection that do not have matching values (supplied via the $values parameter) for the provided $key. This method is capable of filtering collections of both arrays and objects. The whereNotInStrict behaves similarly to the whereNotIn method, the difference is that the whereNotInStrict method always performs strict comparisons.

The whereNotInStrict method does not modify the original collection.

#Signature

1public function whereNotInStrict(
2    $key,
3    $values
4);

#Example Use

The following examples are behaviorally equivalent:

 1$users = collect([
 2    [
 3        'username' => 'Alice',
 4        'isBanned' => true
 5    ],
 6    [
 7        'username' => 'Bob',
 8        'isBanned' => 'true'
 9    ],
10    [
11        'username' => 'Charlie',
12        'isBanned' => 1
13    ]
14]);
15 
16// Using the whereNotIn method and $strict set to true.
17$validUsers = $users->whereNotIn('isBanned', [
18   true
19], true);
20 
21// Using the whereNotInStrict method.
22$validUsers = $users->whereNotInStrict('isBanned', [
23    true
24]);
