如何通过PHP设置URL的内容？ [关闭]

Question

I want to set something to the URL when the page is loading ... How can I do that?

---

When you open this URL:

http://stackoverflow.com/questions/38839016/should-i-store-the-result-of-an-function

automatically it will be replaced with this:

http://stackoverflow.com/questions/38839016/should-i-store-the-result-of-an-function-into-an-array

How does SO do that?

---

Note: I've disabled JavaScript on the browser, still that replacement happens. So it is done by PHP.

It's a simple HTTP redirect. Each question has a slug. When the post slug doesn't match with the slug segment of the url, the HTTP controller redirects the page to the correct route.
