phpFastCache是一个开源的PHP缓存库，只提供一个简单的PHP文件，可方便集成到已有项目，支持多种缓存方法，包括：apc, memcache, memcached, wincache, files, pdo and mpdo。可通过简单的API来定义缓存的有效时间。

减少数据库查询

<?<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>);
    }

    </span><span>//</span><span> Output Your Contents $products HERE</span>

提高cURL和API调用性能

<?<span>php
    </span><span>include</span>("phpfastcache/phpfastcache.php"<span>);

    </span><span>$cache</span> = phpFastCache("memcached"<span>);

    </span><span>//</span><span> try to get from Cache first.</span>
    <span>$results</span> = <span>$cache</span>->get("identity_keyword"<span>)

    </span><span>if</span>(<span>$results</span> == <span>null</span><span>) {
        </span><span>$results</span> = cURL->get("http://www.youtube.com/api/json/url/keyword/page"<span>);
        </span><span>//</span><span> Write to Cache Save API Calls next time</span>
        <span>$cache</span>->set("identity_keyword", <span>$results</span>, 3600*24<span>);
    }

    </span><span>foreach</span>(<span>$results</span> <span>as</span> <span>$video</span><span>) {

    </span><span>$html</span> = __c("files")->get(<span>$keyword_webpage</span><span>);

    </span><span>if</span>(<span>$html</span> == <span>null</span><span>) {
