首先使用phpFastCache :: set设置，然后使用phpFastCache :: get-完成！

示例:减少数据库调用

您的网站有10,000个在线访问者，并且您的动态页面必须在每次页面加载时向数据库发送10,000个相同的查询.使用phpFastCache，您的页面仅向数据库发送1条查询，并使用缓存为9,999位其他访问者提供服务.

Your website have 10,000 visitors who are online, and your dynamic page have to send 10,000 same queries to database on every page load. With phpFastCache, your page only send 1 query to DB, and use the cache to serve 9,999 other visitors.

<?php
    // In your config file
    include("php_fast_cache.php");
    phpFastCache::$storage = "auto";
    // you can set it to files, apc, memcache, memcached, pdo, or wincache
    // I like auto

    // In your Class, Functions, PHP Pages
    // try to get from Cache first.
    $products = phpFastCache::get("products_page");

    if($products == null) {
        $products = YOUR DB QUERIES || GET_PRODUCTS_FUNCTION;
        // set products in to cache in 600 seconds = 5 minutes
        phpFastCache::set("products_page",$products,600);
    }

   OUTPUT or RETURN your $products
?>
