php生成html静态页面的二种方法

$cache = new Cache();2、设置缓存时间和缓存目录

$cache = new Cache(60, '/any_other_path/');

$value = $cache->get('data_key');4、写入缓存

$value = $cache->put('data_key', 'data_value');完整实例：

$cache = new Cache();

//从缓存从读取键值 $key 的数据
$values = $cache->get($key);

//如果没有缓存数据
if ($values == false) {
 //insert code here...
 //写入键值 $key 的数据
 $cache->put($key, $values);
} else {
 //insert code here...
}
