Laravel 8.22 Released

The Laravel team released 8.22 yesterday with a new event fake assertion, a collection method to reduce associative arrays to a single value, and the latest changes in the 8.x branch:

Assert Nothing Dispatched

@danilopolani contributed event assertion assertNothingDispatched to the fake event instance:

Event::fake();

// Function that should NOT dispatch any event
Event::assertNothingDispatched();

Reduce with Keys Collection Method

Mo Khosh contributed a reduceWithKeys method to collections (and lazy collections) to reduce an associative collection to a single value.

Similar to map and mapWithKeys, this augments reduce to pass associative arrays’ keys to its callback. We can’t do that currently because PHP’s array_reduce doesn’t pass array keys to its callback.

Here’s an example from the pull request:

$data = collect([
    'name' => 'Mo Khosh',
    'username' => 'mokhosh',
]);

return $data->reduceWithKeys(function($carry, $value, $key) {
    return $carry . $key . ': ' . $value . PHP_EOL;
});
