此脚本作为 APC、Memcache、Memcached 和文件存储数据的简单接口。

您可以将不同的数据存储到不同的缓存方法中（例如，在 settings-example.php 中的一些示例）。

示例

文件缓存

<?php
include (__DIR__.'/libs/ANS/Cache/Cache.php');
include (__DIR__.'/settings-example.php');

$Cache = new \ANS\Cache\Cache($settings['js']);

if ($Cache->exists('js-files')) {
    $content = $Cache->get('js-files');
} else {
    $content =  file_get_contents('https://ajax.googleapis.ac.cn/ajax/libs/jquery/1.7.2/jquery.min.js');
    $content .= file_get_contents('https://ajax.googleapis.ac.cn/ajax/libs/jqueryui/1.8/jquery-ui.min.js');
    $content .= file_get_contents('http://modernizr.com/i/js/modernizr.com-custom-1.6.js');

    // Cache expired time is loaded from settings
    // but you can set your own time in seconds from now
    // Third parameter is optional
    $Cache->set('js-files', $content, $custom_time);
}

数据库查询缓存（在 APC 中）

<?php
include (__DIR__.'/libs/ANS/Cache/Cache.php');
include (__DIR__.'/settings-example.php');

$Cache = new \ANS\Cache\Cache($settings['db']);

$query = 'SELECT * FROM Users;';
$cache_key = md5($query);

if ($Cache->exists($cache_key)) {
    $rows = $Cache->get($cache_key);
} else {
    $rows = mysql_fetch_assoc(mysql_query($query));

    // Cache expired time is loaded from settings
    // but you can set your own time in seconds from now
    // Third parameter is optional
    $Cache->set($cache_key, $rows, $custom_time);
}

配置缓存（在 Memcache 中）

<?php
include (__DIR__.'/libs/ANS/Cache/Cache.php');
include (__DIR__.'/settings-example.php');

$Cache = new \ANS\Cache\Cache($settings['config']);

$config_files = array(
    'db', 'paths', 'events', 'routes', 'templates', 'mail',
    'session', 'tables', 'actions', 'css', 'languages'
);

$config_key = md5(serialize($config_files));

if ($Cache->exists($cache_key)) {
    $configuration = $Cache->get($cache_key);
} else {
    $configuration = array();

    foreach ($config_files as $file) {
        if (is_file(__DIR__.'/config/'.$file.'.php')) {
            $configuration = array_replace_recursive($configuration, include(__DIR__.'/config/'.$file.'.php'));
        }
    }

    // Cache expired time is loaded from settings
    // but you can set your own time in seconds from now
    // Third parameter is optional
    $Cache->set($cache_key, $configuration, $custom_time);
}
