$collection = IterableCollection::fromArray([1, 2, 3, 4, 5]);
Example Usage
$iterable = function () { for ($i = 1; $i <= 5; $i++) { yield $i; } }; $result = IterableCollection::fromGenerator($iterable()) ->map(function ($value) { return $value * 10; }) ->filter(function ($value) { return $value > 30; }) ->reduce(function ($acc, $value, $startValue) { return $acc + $value; }); // $result = 90
