php-kit / flow example snippets


use PhpKit\Flow\Flow;

$topCustomers = Flow::from($orders)
    ->expand(fn ($order) => $order['line_items'])
    ->map(fn ($item) => $item['customer'])
    ->where(fn ($customer) => $customer['active'])

foreach (Flow::from([1, 2, 3]) as $value) {
    echo $value;
}


// Flow works seamlessly with SPL functions
$count = iterator_count(Flow::from([1, 2, 3])->where(fn($x) => $x > 1));

// Or with any function expecting a Traversable
function processItems(Traversable $items) {
    foreach ($items as $item) {
        // process each item
    }
}

processItems(Flow::from($data)->map($transformer));


$values = Flow::from(function () {
    for ($i = 1; $i <= 3; $i++) {
        yield $i;
    }
});
