博客系统-3.0CodeIgniter系统SAE版本的配置 application/config/

1. autoload.php(系统启动时自动加载的文件：包，类库，驱动，方法助手，配置)
1. $autoload['libraries'] = array('database', 'access', 'pagination');//类库：数据库/权限类/分页类
2. $autoload['drivers'] = array('session');//驱动：session
3. $autoload['helper'] = array('url', 'file', 'cookie', 'form', 'array');//方法：url，文件，cookie，表单，数组
4. $autoload['config'] = array('app');//配置：项目
2. config.php 项目公共配置
1. $config['enable_hooks'] = TRUE;//使用钩子
2. $config['log_threshold'] = 0;//日志记录级别
3. $config['log_path'] = '';//日志路径
4. $config['cache_path'] = '';//缓存路径
5. $config['encryption_key'] = 'blog_;//session加密
6. $config['sess_expiration']        = 3600;//session过期时间
7. $config['sae_output_cache'] = 'kvdb';//输出类页面缓存配置
3. constants.php 静态变量
1. define('PAGE_LIMIT', 10);//每页条数
4. database.php 数据库，判断是否SAE环境，调用不同配置
1. 判断是否是SAE环境

        * 检查是否是SAE环境

1. routes.php 默认路由
