本文实例讲述了CI框架(CodeIgniter)操作redis的方法。分享给大家供大家参考,具体如下:
1. 在autoload.php 中加入 如下配置行
$autoload['libraries'] = array('redis');
2. 在/application/config 中加入文件 redis.php
文件内容如下:

(1)你的本地需要安装 redis服务(windows安装)
(2)并开启redis 服务
(3)不管是windows 还是linux 都需要装 php对应版本的 redis扩展更多关于CodeIgniter相关内容感兴趣的读者可查看本站专题:《codeigniter入门教程》、《CI(CodeIgniter)框架进阶教程》、《php优秀开发框架总结》、《ThinkPHP入门教程》、《ThinkPHP常用方法总结》、《Zend FrameWork框架入门教程》、《php面向对象程序设计入门教程》、《php+mysql数据库操作入门教程》及《php常见数据库操作技巧汇总》
