在简单的mvc中使用模型到控制器

Question

I use this mvc. Now I want to know how can I use of the data of model into controller ?

here is a line of code:

$registry->db = db::getInstance();

but the above code is not working on the controller, I can use db::getInstance(); in the controller directly. but I can not use $registry->db instead of it. why ?

finally, how can I use of model into controller ?

Answer 1

All properties to $registry are set to private, so you'll have to store it somewhere else:

$db = db::getInstance();
