<?php

/**
 * @return Generator<WC_Product>
 */
function fetch_all_products(): Generator {
	$page = 1;

	while ( true ) {
		$products = wc_get_products( [
			'limit' => 100,
			'page'  => $page++,
		] );

		if ( ! is_array( $products ) || empty( $products ) ) {
			return;
		}

		foreach ( $products as $product ) {
			yield $product;
		}
	}
}

// Iterate across the entire product catalog.
foreach ( fetch_all_products() as $product ) {
	print $product->get_id() . ' ' . $product->get_name() . PHP_EOL;
