[PHP-NOTES] note 130257 added to function.array-find

A simple fallback For older PHP versions, that do not have array_find:

<?php
function array_find(array $array, callable $callback): mixed {
	foreach ($array as $key => $value) {
		if ($callback($value, $key)) {
			return $value;
		}
	}

	return null;
}
?>
