如何暂停当前PHP脚本的执行？

Question

I'm writing some simple PHP to back up a microsite. In my controller, I have a quick security/sanity check

if(!preg_match('/^[a-z]$/i', $req)) { gohome(); }

I'd like to continue my the main code after this, but for aesthetics, I'd like to avoid putting the rest of it inside the else block. What's the best way around this? I can think of setting up a fairly simple wrapper to handle authentication and security logic, but I feel like I just missed a really simple solution in my training.

You can use the die/exit function to end the script with (or without) an error.
