标签: php mysql caching

我为缓存的MySQL结果找到了phpfastcahce类。在支持WinCache,MemCache,文件,X-Cache,APC Cache的详细信息中说:

PHP Caching Class For Database : 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.

示例代码中的

<?php
    // In your config file
    include("php_fast_cache.php");
    // This is Optional Config only. You can skip these lines.
    // phpFastCache support "apc", "memcache", "memcached", "wincache" ,"files", "pdo", "mpdo" and "xcache"
    // You don't need to change your code when you change your caching system. Or simple keep it auto
    phpFastCache::$storage = "auto";
    // End Optionals

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

    if($products == null) {
        $products = YOUR DB QUERIES || GET_PRODUCTS_FUNCTION;
        // set products in to cache in 600 seconds = 10 minutes
        phpFastCache::set("products_page",$products,600);
    }

    foreach($products as $product) {
        // Output Your Contents HERE
    }
?>

现在,在我的网站索引中,我有任何阻止显示最新消息,最佳新闻,世界新闻.....缓存我的索引,我必须为每个块{{1}缓存MySQL结果如果我编辑现有新闻或添加新消息,使用phpfastcache并在管理页面中删除所有缓存?这是一种真实的方式吗?

什么是最好的方法对于缓存(last news, best news, world news ..... )使用 phpfastcache (任何方法)导致我的索引页面?!

phpfastcache无法理解您的数据是否已更改

您必须在数据库中更改特定数据后执行某些操作

首先在你的主页缓存代码必须是这样的:

$lastnews = phpFastCache::get('index_lastnews');
$bestnews = phpFastCache::get('index_bestnews');
$worldnews = phpFastCache::get('index_worldnews');

if($lastnews == null) {
    $lastnews = YOUR DB QUERIES || GET_DATA_FUNCTION;
    phpFastCache::set('index_lastnews',$lastnews,600);
}
if($bestnews == null) {
    $bestnews = YOUR DB QUERIES || GET_DATA_FUNCTION;
    phpFastCache::set('index_bestnews',$bestnews,600);
}

。 。

并且在您的管理页面中,当特定数据更改缓存代码时必须如下所示:

AFTER DATABASE insert | update ....

您可以通过以下两种方式替换旧缓存:

1)删除缓存(删除缓存后,首次访问后缓存自动重建)

phpFastCache::delete('index_lastnews');

2)更新缓存

$lastnews =   YOUR DB QUERIES || GET_DATA_FUNCTION;
phpFastCache::set("index_lastnews",$lastnews,600);
