減少資料庫查詢

<?<span>php </span><span>//</span><span> In your config file</span> <span>include</span>("phpfastcache/phpfastcache.php"<span>);
    phpFastCache</span>::setup("storage","auto"<span>); </span><span>//</span><span> phpFastCache support "apc", "memcache", "memcached", "wincache" ,"files", "sqlite" and "xcache"
    // You don't need to change your code when you change your caching system. Or simple keep it auto</span> <span>$cache</span> =<span> phpFastCache(); </span><span>//</span><span> In your Class, Functions, PHP Pages
    // try to get from Cache first. product_page = YOUR Identity Keyword</span> <span>$products</span> = <span>$cache</span>->get("product_page"<span>); </span><span>if</span>(<span>$products</span> == <span>null</span><span>) { </span><span>$products</span> = YOUR DB QUERIES ||<span> GET_PRODUCTS_FUNCTION; </span><span>//</span><span> set products in to cache in 600 seconds = 10 minutes</span> <span>$cache</span>->set("product_page", <span>$products</span>,600<span>);
