Php ile mümkün müdür?

$content = htmlspecialchars_decode($page['page_content']);

$explode = explode(PHP_EOL, $content);
$title = $explode[0]; // Burası ilk satır
unset($explode[0]); // ilk satırı içerikten sil
$content = implode(PHP_EOL, $explode); // içeriği yeniden birleştir
echo '<h1>'.$title.'</h1>';
echo '<p>'.$content.'</p>';

$explode = explode(PHP_EOL, $content);
$title = $explode[0]; // Burası ilk satır
unset($explode[0]); // ilk satırı içerikten sil
$content = implode(PHP_EOL, $explode); // içeriği yeniden birleştir
echo '<h1>'.$title.'</h1>';
echo '<p>'.$content.'</p>';
