I have added the code below to my WooCommerce site to display the file format of a downloadable asset.

to be displayed on a single product page

For ZIP files, I would like the display to indicate the files which are contained within the compressed archive, so the shoppers of simple/downloadable products know the formats of the product data which they will receive. How can this be achieved please?

global $product;
$downloads = $product->get_files();
foreach( $downloads as $key => $each_download ) {
  $info     = pathinfo($each_download["file"]);
  $ext      = $info['extension'];
  $formats .= $ext . ", ";
}
echo '<p> File Format: '. $formats .'</p>';
?>```

You can use the ZipArchive to gather the index of the files within the zip.

Ensure that you have the module installed as detailed here https://www.php.net/manual/en/zip.installation.php

public function buildZipBreakdown(string $zipFile): array
{
    $result = [];
    if (file_exists($zipFile)) {
        $result = pathinfo($zipFile);
        if ($result['extension'] == "zip") {
            $za = new ZipArchive();
            $za->open($zipFile);
            $result['num_files']  = $za->numFiles;
            if ($za->numFiles>0) {
                $result['files'] = [];
                for ($i=0; $i<$za->numFiles; $i++) {
                    $file_object = $za->statIndex($i);
                    $result['files'][] = [
                        "filename" => $file_object['name'],
                        "size" => $file_object['size'],
                        "date" => date('Y-m-d H:i:s', $file_object['mtime'])
                    ];
                }
            } else {
                throw new Exception("EMPTY_INVALID_ZIP");
            }
        } else {
            throw new Exception("NOT_ZIP_EXT");
        }
    } else {
        throw new Exception("NOT_FOUND");
    }
    return  $result;
}

You can tailor it to your needs.

Hello like @user6316291 said, zipArchive works.
Since it’s in WooCommerce, you can try this code.

<?php
/*
 * This block should be in the proper place of mytheme/woocommerce/templates/single-product/meta.php file.
 * Hope this helps you, but still, enjoy at your own risk. :)
 */

/**
 * Single Product Meta
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/single-product/meta.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see         https://docs.woocommerce.com/document/template-structure/
 * @package     WooCommerceTemplates
 * @version     3.0.0
 */
if ( ! defined( 'ABSPATH' ) ) {
    exit;
}
global $product;
?>
<div class="product_meta">
    <?php do_action( 'woocommerce_product_meta_start' ); ?>
    <?php if ( wc_product_sku_enabled() && ( $product->get_sku() || $product->is_type( 'variable' ) ) ) : ?>
        <span class="sku_wrapper"><?php esc_html_e( 'SKU:', 'woocommerce' ); ?> <span class="sku"><?php echo ( $sku = $product->get_sku() ) ? $sku : esc_html__( 'N/A', 'woocommerce' ); ?></span></span>
    <?php endif; ?>
    <?php echo wc_get_product_category_list( $product->get_id(), ', ', '<span class="posted_in">' . _n( 'Category:', 'Categories:', count( $product->get_category_ids() ), 'woocommerce' ) . ' ', '</span>' ); ?>
    <?php echo wc_get_product_tag_list( $product->get_id(), ', ', '<span class="tagged_as">' . _n( 'Tag:', 'Tags:', count( $product->get_tag_ids() ), 'woocommerce' ) . ' ', '</span>' ); ?>


    <?php do_action( 'woocommerce_product_meta_end' ); ?>
