求教各位大神PHP工程模式如何传入参数？

反射一下

class test{
    function __construct($config = ''){
        if(!empty($config)){
            var_dump($config);
        }else{
            echo 'no params';
        }
    }
}
function Factory($classname, $params='') {
     if(!empty($params) ){
        $reflect  = new ReflectionClass($classname);
        return $reflect->newInstanceArgs($params);
     }else{
        return new $classname();
     }

}
$config_test = array('a','b','c');
Factory('test');
Factory('test', $config_test);
