重定向还是死？ 这些死亡陈述有用吗？

Question

Inherited a Cakephp application which uses a great deal of $this->redirect($url) statements; all of them are followed by die(); as follows:

$this->redirect($url);
die();

I can only assume this is some poor form of error trapping, but I can't see why this would ever be necessary. $this->redirect uses a URL redirect function from my framework, nothing our application has altered; if it doesn't work then my framework doesn't work, so nothing on the whole site would work in the first place. The die(); statements make it very hard to weed through the code and find where errors were expected (they're not using exceptions of course).

Is there any reason to keep these? The only functionality I can imagine they provide is to prevent execution of logic beyond a redirect in a function that wasn't supposed to execute, but it looks like bad unnecessary coding to me.

You can read the source . function redirect($url, $status = null, $exit = true) the $exit is default true and @param boolean $exit If true, exit() will be called after the redirect
