Joomla template override PHP initializing variable

Question

I'm trying to create an override for my template to customize the way an extension should display it's fields in the article.

The extension I use is DPfields and I'm using this reference guide from the developer: https://joomla.digital-peak.com/documentation/162-dpfields/2750-rendering-fields

Expecially I'm referencing to the paragraph: Accessing the fields in the layout

I've created a new php file started from the default.php file for article view and inside this new file (newfile.php) I'm trying to display a gallery field type from the component DPField.

I've succesfully inserted this code in the newfile.php:

<?php
    foreach ($this->item->dpfields as $field) {
        $gallery = (($field->type)=='gallery');
        if (!empty($gallery)) {
            echo '<div class="galleryfield">' .$field->value. '</div>'; 
        }
    }
?>

so it correctly shows in the output the gallery.

My question is: how could I improve that code? Is there a better way to let it work instead of using a foreach?

Thanks in advance.

You can try to filter the array. It'll not change the amount of code you need I guess.

function filterForGalleryType($field) {
  return ($field->type) == 'gallery';
}

$galleryFields = array_filter($this->item->dpfields, "filterForGalleryType");

foreach ($galleryFields as $galleryfield) {
  echo '<div class="galleryfield">' .$galleryfield->value. '</div>'; 
}
