在CodeIgniter的“视图”末尾添加die（）是不好的做法吗？ [关闭]

Question

In order to make things right and prevent CodeIgniter from loading another views after a loaded view I needed to added die() at the end of views (footer). Is this a bad practice and Will this cause any problems?

The code is a little bit large to be posted here but I can say that there is an if statement which loads a view and by default the function loads another view. So when if statement gets passed, It loads the defined view and then the function loads the default view after it. I can use die() inside my controller but it gives me a blank page meaning that die() got executed before loading the view. and I can't neither use redirect().

It is a bad practice. The end of the method at controller level is not the actual end of the execution of the code related to the request. Codeignitor has a setup of loading a controller and then calling its method, and then executing other code after the method execution has finished.

Apart from the CodeIgnitor internal code, there are hooks

if you have defined "post controller" hooks, which get executed after the controller method has finished,those will not be executed if you put die in your code.
