33 | require dirname(__FILE__).'/config/config.php'; 34 | Application::run($CONFIG); 35 | 36 | 入口文件主要做了2件事，第一引入系统的驱动类，第二是引入配置文件，然后运行run（）方法，传入配置作为参数，具体这2个文件是什么内容，我们接下来继续看。 37 | 38 | 先看一下config/config.php文件，里面其实是一个$CONFIG变量，这个变量存放的全局的配置： 39 | 40 | 45 | * @version 1.0 46 | */ 47 | 48 | /*数据库配置*/ 49 | $CONFIG['system']['db'] = array( 50 | 'db_host' => 'localhost', 51 | 'db_user' => 'root', 52 | 'db_password' => '', 53 | 'db_database' => 'app', 54 | 'db_table_prefix' => 'app_', 55 | 'db_charset' => 'urf8', 56 | 'db_conn' => '', //数据库连接标识; pconn 为长久链接，默认为即时链接 57 | 58 | ); 59 | 60 | /*自定义类库配置*/ 61 | $CONFIG['system']['lib'] = array( 62 | 'prefix' => 'my' //自定义类库的文件前缀 63 | ); 64 | 65 | $CONFIG['system']['route'] = array( 66 | 'default_controller' => 'home', //系统默认控制器 67 | 'default_action' => 'index', //系统默认控制器 68 | 'url_type' => 1 /*定义URL的形式 1 为普通模式 index.php?c=controller&a=action&id=2 69 | * 2 为PATHINFO index.php/controller/action/id/2(暂时不实现) 70 | */ 71 | ); 72 | 73 | /*缓存配置*/ 74 | $CONFIG['system']['cache'] = array( 75 | 'cache_dir' => 'cache', //缓存路径，相对于根目录 76 | 'cache_prefix' => 'cache_',//缓存文件名前缀 77 | 'cache_time' => 1800, //缓存时间默认1800秒 78 | 'cache_mode' => 2, //mode 1 为serialize ，model 2为保存为可执行文件 79 | ); 80 | 81 | 我这里有意识的定义$CONFIG['system']数组表示是系统的配置文件，当然你可以在里面定义$CONFIG['myconfig']为表示在定义的配置，以后在程序的控制器，模型，视图中来调用，都个很自由。 82 | 具体配置值代表什么意思注视很清楚了，下面的如果程序中有详细注释的我就不解释啦，呵呵 83 | 84 | 再来看一下system/app.php文件，主要是干嘛的： 85 | 86 | 91 | * @version 1.0 92 | */ 93 | define('SYSTEM_PATH', dirname(__FILE__));

//设置url的类型 266 | $url_array = self::$_lib['route']->getUrlArray(); //将url转发成数组 267 | 好吧，我们来看下route的系统类到底做了说明 268 | 269 | 274 | * @version 1.0 275 | */ 276 | final class Route{ 277 | public $url_query;
