<div class="correspondent__stories" <?= $this->next ?>>
    <? foreach($this->stories as $story): ?>
        <h2><?= $story['headline'] ?></h2>
    <? endforeach; ?>
</div>


<?

// ...

$this->next = $this->getNext();

private function getNext()
{
  return $this->stories->hasNextPageLink() ? sprintf('data-next="%s"', $this->stories->getNextPageLink()) : '';
}

// ...

?>

if $story is an object.....

class Story {
    ....
    public function __toString()
    {
        return $this->headline;
    }
}

then it can be

    <? foreach($this->stories as $story): ?>
        <h2><?= $story ?></h2>
    <? endforeach; ?>
