A simple implementation of a php framework, only implementing a simple routing layer-PHP Tutorial-php.cn

First look at the existing file directory

DOCUMENT_ROOR is /home/www directory

Then look at the contents of the entry file

1) { $controller = $params[0]; $action = $params[1]; unset($params[0]); unset($params[1]); }else if($params_count==1) { $controller = $params[0]; $action = 'index'; unset($params[0]); } $filename = strtolower($controller).'.php'; $controller_path = $_SERVER['DOCUMENT_ROOT'].'/application/controllers/'; if(!file_exists($controller_path.$filename)) { throw new Exception('controller '.$filename.' is not exists!'); return; } include($controller_path.$filename); $classname = ucfirst($controller); if(!class_exists($classname)) { throw new Excpetion('class '.$classname.' is not exists!'); } $reflecObj = new ReflectionClass($classname); if(!$reflecObj->hasMethod($action)){ throw new Exception('method '.$action.' is not exists!'); } $currentObj = new $classname(); echo "classname=$classname,action=$action,params=".json_encode($params)."
"; call_user_func_array([$currentObj,$action],$params); return; ?>

Copy after login

Then create a simple controller user.php and put it in the applicaiton/controllers/ directory with the specific content As follows:


        
         Copy after login

Finally test a correct controller jump and an incorrect controller jump

First test the correct process: http://192.168.1.99/user /index/xiaoming

Output content:

classname=User,action=index,params={"2":"xiaoming"} hello,xiaoming,lucky,you are arrive here!

Copy after login

Test the non-existent controller again, http://192.168.1.99/account/index/xiaoming

Fatal error: Uncaught exception 'Exception' with message 'controller acount.php is not exists!' in /home/www/webroot/index.php:25Stack trace:#0 {main} thrown in /home/www/webroot/index.php on line 25
