// [output] 2, 4, 6
```

### `Generator map_kv(iterable $iter, callable $callback)`

[](#generator-map_kviterable-iter-callable-callback)

```
$data = ['apple', 'orange', 'strawberry'];
$deco = function ($k, $v) { return "{$k}: $v"; };

foreach (map_kv($data, $deco) as $a) {
    echo $a, PHP_EOL;
}
// [output] "1: apple", "2: orange", "3: strawberry"
