继续 codeigniter.php

line 248 include(APPPATH.'controllers/'.$RTR->fetch_directory().$RTR->fetch_class().'.php');

这句话就是加载跟当前类同名的控制器

line 262 $class = $RTR->fetch_class();
line 263 $method = $RTR->fetch_method();

路由加载默认的类和方法名（默认是index）

line 300 - line340

if (method_exists($CI, '_remap')){$CI->_remap($method, array_slice($URI->rsegments, 2));}else{// is_callable() returns TRUE on some versions of PHP 5 for private and protected// methods, so we'll use this workaround for consistent behaviorif ( ! in_array(strtolower($method), array_map('strtolower', get_class_methods($CI)))){// Check and see if we are using a 404 override and use it.if ( ! empty($RTR->routes['404_override'])){$x = explode('/', $RTR->routes['404_override']);$class = $x[0];$method = (isset($x[1]) ? $x[1] : 'index');if ( ! class_exists($class)){if ( ! file_exists(APPPATH.'controllers/'.$class.'.php')){show_404("{$class}/{$method}");}include_once(APPPATH.'controllers/'.$class.'.php');unset($CI);$CI = new $class();}}else{show_404("{$class}/{$method}");}}// Call the requested method.// Any URI segments present (besides the class/function) will be passed to the method for conveniencecall_user_func_array(array(&$CI, $method), array_slice($URI->rsegments, 2));}

这段是调用控制器中的方法。

get_class_methods 获取类中的方法

call_user_func_array 调用指定的方法

get_object_vars 对象转换成数组

if ($EXT->_call_hook('display_override') === FALSE){$OUT->_display();}

将结果输出到浏览器

if (class_exists('CI_DB') AND isset($CI->db)){$CI->db->close();}

如果数据库打开关闭数据库连接

codeigniter.php 结束了，一个程序也就运行完了
