\##Xiuno BBS 4.0 中的幾種緩存 API 1. 持久存儲，永不過期 kv\_set('key1','value1');kv\_get('key1');kv\_delete('key1'); 1. 緩存，可以設置過期時間 cache\_set('key1','value1',60);cache\_get('key1');cache\_delete('key1'); 1. 持久存儲，CACHE加速 kv\_cache\_set('key1','value1');kv\_cache\_get('key1');kv\_cache\_delete('key1'); 1. 合并到setting進行存儲，持久存儲，并且通過cache加速（如果開啟cache） setting\_set('key1');setting\_get('key1','value1');setting\_delete('key1'); 1. 合并到runtime中進行存儲，持久存儲，并且通過cache加速（如果開啟cache） runtime\_set('key1');runtime\_get('key1','value1');runtime\_delete('key1');
