PHP header [removed] - what are the implications?

Question

I have domain.com. If the user is logged in, it should load automatically domain.com/option-X where X is a predefined choice of the user.

Answer 1

The effect of the 301 would be that the search engines will index /option-a instead of /option-x. Which is probably a good thing since /option-x is not reachable for the search index and thus could have a positive effect on the index. Only if you use this wisely ;-)

After the redirect put exit(); to stop the rest of the script to execute

header("HTTP/1.1 301 Moved Permanently"); 
header("Location: /option-a"); 
exit();
