## 1 框架入口
### 1-1安装入口 (install.php)
~~~
if(version_compare(PHP_VERSION,'5.3.0','<')) die('require PHP > 5.3.0 !');
~~~
> 检查php版本信息
~~~
define ( 'APP_DEBUG', true );
~~~
> 开始调试模式
`define ( 'BIND_MODULE','Install');`
>[info] 设置绑定模块为Install,路由解析是模块解析到安装模块
`define ( 'APP_PATH', './Application/' );`
> 应用目录
`define ( 'RUNTIME_PATH', './Runtime/' );`
> 缓存目录
`require './ThinkPHP/ThinkPHP.php';`
> 加载框架引导文件，启动框架
### 默认入口 (index.php)
~~~
if(version_compare(PHP_VERSION,'5.3.0','<')) die('require PHP > 5.3.0 !');
define('APP_DEBUG', true );
define ( 'APP_PATH', './Application/' );
~~~
> 同上。
> 检查php版本，
> 开启调试模式，
> 设置应用目录
~~~
if(!is_file(APP_PATH . 'User/Conf/config.php')){
header('Location: ./install.php');
exit;
}
~~~
>[info] 检查是否需要安装，
~~~
define ( 'RUNTIME_PATH', './Runtime/' );
require './ThinkPHP/ThinkPHP.php';
~~~
> 同上。
> 设置缓存目录，
> 加载框架引导文件，启动框架
### 后台入口 (admin.php)
~~~
if(version_compare(PHP_VERSION,'5.3.0','<')) die('require PHP > 5.3.0 !');
define('APP_DEBUG', true );
~~~
> 同上
检查php版本
开启调试模式
`define('BIND_MODULE','Admin');`
>[info] 设置绑定模块为Admin，路由解析到后台模块
