How to clear cache programatically ?

I want to clear cache of a page ( single product page ) when ever the stock status changes, Is there any way I can clear and regenerate cache for single-product page on woocommerce_product_set_stock hook,

I tried

add_action( 'woocommerce_product_set_stock', 'le_product_stock_status_update' );
if ( is_plugin_active( 'wp-super-cache/wp-cache.php' ) ){
function le_product_stock_status_update($post_id = '') {

        global $blog_cache_dir, $wp_cache_object_cache;

        if ( $wp_cache_object_cache ) {
            reset_oc_version();
        } else {
            prune_super_cache( $blog_cache_dir, true );
            prune_super_cache( get_supercache_dir(), true );
        }
    }
}
