看输出日志 写的流程，请大家指正
查看了流程DEBUG - 2012-06-29 10:33:45 --> Config Class InitializedDEBUG - 2012-06-29 10:33:45 --> Hooks Class InitializedDEBUG - 2012-06-29 10:33:45 --> Utf8 Class InitializedDEBUG - 2012-06-29 10:33:45 --> UTF-8 Support EnabledDEBUG - 2012-06-29 10:33:45 --> URI Class InitializedDEBUG - 2012-06-29 10:33:45 --> Router Class InitializedDEBUG - 2012-06-29 10:33:45 --> Output Class InitializedDEBUG - 2012-06-29 10:33:45 --> Security Class InitializedDEBUG - 2012-06-29 10:33:45 --> Input Class InitializedDEBUG - 2012-06-29 10:33:45 --> Global POST and COOKIE data sanitizedDEBUG - 2012-06-29 10:33:45 --> Language Class InitializedDEBUG - 2012-06-29 10:33:45 --> Loader Class Initialized这个是初始化要经历的步骤上述日志是由于调用了function log_message($level = 'error', $message, $php_error = FALSE)1 Index.php会载入CodeIgniter.php- require(BASEPATH.'core/Common.php'); 载入公共函数- require(APPPATH.'config/constants.php'); 载入文件和目录的模式配置- get_config(array('subclass_prefix' => $assign_to_config['subclass_prefix']));若在index中设置$assign_to_config['subclass_prefix'],加载config文件，并替换扩展的前缀- $BM =& load_class('Benchmark', 'core'); 载入基准测试函数，定义了程序的开始时间- $EXT =& load_class('Hooks', 'core'); 会同时加载 config,所以在log中,config会在hooks前面- $EXT->_call_hook('pre_system'); 调用hooks中数组名称为pre_system的并执行- $CFG =& load_class('Config', 'core'); 已经调用过了，所以不会再加载，因此在日志中也没有体现- if (isset($assign_to_config)) 在index.php中是否有- $UNI =& load_class('Utf8', 'core'); //初始化，并判断是否支持UTF-8的环境，因此在日志中会有 UTF-8 Support Enabled- $URI =& load_class('URI', 'core');- $RTR =& load_class('Router', 'core'); //- $OUT =& load_class('Output', 'core'); //加载输出函数- if ($EXT->_call_hook('cache_override') === FALSE) //加载钩子中的- $SEC =& load_class('Security', 'core');运行安全函数- $IN =& load_class('Input', 'core'); 加载输入函数- $LANG =& load_class('Lang', 'core');加载语言包- require BASEPATH.'core/Controller.php';- include(APPPATH.'controllers/'.$RTR->fetch_directory().$RTR->fetch_class().'.php'); 加载相应的控制器- $BM->mark('loading_time:_base_classes_end');- if ( ! file_exists(APPPATH.'controllers/'.$class.'.php')) 加载404错误文件 $x = explode('/', $RTR->routes['404_override']);- $EXT->_call_hook('pre_controller'); 钩子加载- $BM->mark('controller_execution_time_( '.$class.' / '.$method.' )_start'); 计算加载时间- $CI = new $class(); 加载函数- $EXT->_call_hook('post_controller_constructor'); 在构造函数之前- call_user_func_array(array(&$CI, $method), array_slice($URI->rsegments, 2));运行函数- $BM->mark('controller_execution_time_( '.$class.' / '.$method.' )_end'); 控制器运行完成- $EXT->_call_hook('post_controller'); 在控制器执行完后 ，运行钩子- $EXT->_call_hook('display_override') 若没有显示覆盖的钩子- $OUT->_display(); 运行输出- $EXT->_call_hook('post_system'); 在输出后，运行钩子post_system- $CI->db->close(); 关闭数据库连接
