回复讨论(解决方案)
根据controler与action，判断要调用的类与方法
$act_file = realpath(BASE_PATH.'/control/'.$_GET['act'].'.php');$class_name = $_GET['act'].'Control';
然后判断如果类和方法存在则调用，就这样。
if (class_exists($class_name)){ $main = new $class_name(); $function = $_GET['op'].'Op'; if (method_exists($main,$function)){ $main->$function(); }elseif (method_exists($main,'indexOp')){ $main->indexOp(); }else { $error = "Base Error: function $function not in $class_name!"; throw_exception($error); } }
