memcache 形式的缓存php 扩展需求

    1. 需要开启 php_memcache 扩展

    memcache 相关知识：http://www.hcoder.net/books/read_10090.html

    修改全局配置 phpGrace/config.php

    1. 'cache' => array(
    2.     'type'          => 'memcache',
    3.     //以下配置为memcache及redis类型缓存的必须设置
    4.     'host'          => '127.0.0.1', //主机地址
    5.     'port'          => '11211',     //端口
    6.     'pre'           => 'grace_'     //缓存变量前缀
    7. )

    调用演示

    1. <?php
    2. class indexController extends grace{
    3.     public function index(){
    4.         $this->cache('test', 12, '__getData');
    5.         p($this->test);
    6.     }
    7.  
    8.     public function __getData(){
    9.         echo '无缓存，进行查询...<br />';
    10.         $db = db('persons');
    11.         $persons = $db->fetchAll();
    12.         return $persons;
    13.     }
    14.  
    15.     public function t(){
    16.         $this->removeCache('test', '12');
    17.     }
    18. }
