Answer 1

Use \iter\search() from nikic's iter library of primitive iteration functions. It has the added benefit that it operates on both arrays and Traversable collections.

$foundItem = \iter\search(function ($item) {
    return $item > 10;
}, range(1, 20));

if ($foundItem !== null) {
    echo $foundItem; // 11
}
