masalahnya disini, kamu tidak memberitahu array yang ingin di looping,, jadi kami tidak tahu musti apa yang di looping, dan harus menggunakan apa,, (while, for, atau yang lainnya)
misal aja kita punya array data portfolio,, maka, mungkin bisa dibuat seperti ini

<?php
// Data portfolio dalam bentuk array
$portfolio = array(
  array(
    'filter' => 'filter-app',
    'image' => 'assets/img/portfolio/portfolio-1.jpg',
    'title' => 'App 1',
    'category' => 'App'
  ),
  array(
    'filter' => 'filter-card',
    'image' => 'assets/img/portfolio/portfolio-8.jpg',
    'title' => 'Card 3',
    'category' => 'Card'
  ),
  array(
    'filter' => 'filter-web',
    'image' => 'assets/img/portfolio/portfolio-9.jpg',
    'title' => 'Web 3',
    'category' => 'Web'
  )
);

// Looping portfolio
foreach ($portfolio as $item) {
  echo '<div class="col-lg-4 col-md-6 portfolio-item ' . $item['filter'] . '">';
  echo '<div class="portfolio-wrap">';
  echo '<img src="' . $item['image'] . '" class="img-fluid" alt="">';
  echo '<div class="portfolio-links">';
  echo '<a href="' . $item['image'] . '" data-gallery="portfolioGallery" class="portfolio-lightbox" title="' . $item['title'] . '"><i class="bi bi-plus"></i></a>';
  echo '<a href="portfolio-details.html" title="More Details"><i class="bi bi-link"></i></a>';
  echo '</div>';
  echo '<div class="portfolio-info">';
  echo '<h4>' . $item['title'] . '</h4>';
  echo '<p>' . $item['category'] . '</p>';
  echo '</div>';
  echo '</div>';
  echo '</div>';
}
?>
