function products()
{
    $cache = __DIR__ . "/json.cacheAllProducts.txt";

    $count = 0;
    $full_product_list = array();
    $loop = new WP_Query(array('post_type' => array(
        'product',
        'product_variation'
    ), 'posts_per_page' => -1));
    $handle = fopen($cache, 'wb') or die('no fopen');

    while ($loop->have_posts()) : $loop->the_post();
        $theid = get_the_ID();
        $product = new WC_Product($theid);
        $thetitle = get_the_title();

        $produtslist[] = array(
            'ID' => $theid,
            'price' => $curlcontent
        );

        fwrite($handle, print_r(($produtslist), true));
        $json_cache = file_get_contents($cache);
        $data2 = json_decode($json_cache);

        echo $json_cache;
    endwhile;

    fclose($handle);
